Spring into Action: Imagining a Future Beyond Landfills

wont.socialise@gmail.com — Sun, 31 Aug 2025 08:00:24 +0000

There was a time when landfills were the final stop in a long, linear journey of consumption. But what if they weren’t? What if waste didn’t end up buried in the ground. But reimagined, repurposed, and reintegrated into the economy?

As we enter the realm of possibilities, the concept of zero waste to landfill becomes more than just a sustainability goal – it becomes a design principle for the future. One that dares to ask: what if nothing was wasted at all?

This September, we open that conversation. Because the innovations that can get us there aren’t science fiction, they’re already here, quietly transforming how we think about waste, value, and regeneration.

The Vision: A World Without Waste

In a zero waste-to-landfill future:

Products are designed for repair, reuse, or disassembly
Food waste fuels biogas or regenerative compost systems
Plastics are replaced with biodegradable alternatives
Buildings are constructed with recycled or modular materials
Waste sorting is enhanced by AI and robotics
Communities participate in hyper-local circular systems

It’s not perfect – yet. But it’s possible. And in South Africa, a country with limited landfill space and growing waste volumes, it’s not just a possibility. It’s a necessity.Transformative Technologies on the Rise

AI‑Powered Sorting

Robotic sorting systems powered by machine vision, such as Europe’s ZenRobotics, are boosting recovery rates in materials recovery facilities by up to 60% by identifying and extracting valuable recyclables with precision. These innovations are inspiring similar pilots for plastic and e-waste sorting in South Africa.

Design for Disassembly & Reusable Packaging

Globally, manufacturers are shifting toward product designs, like modular electronics or refillable containers, that are easier to repair or recycle. In South Africa, frameworks promoting reusable packaging and bulk bin systems are emerging, offering alternatives to single-use waste.

Waste‑to‑Energy 2.0: Pyrolysis & Gasification

Advanced thermal technologies such as pyrolysis and gasification are being piloted in South Africa, notably in Gauteng where tyre-derived waste can be processed into syngas and energy. These methods offer cleaner energy alternatives to conventional incineration.

Biodegradable & Bio‑Based Materials

Innovative packaging made from cassava, algae, or maize starch is gaining traction. These compostable materials degrade within 60–90 days, making them well-suited for municipalities with organic waste infrastructure and reducing plastic pollution.

Leading Possibility into Practice

Interwaste’s commitment to a future beyond landfill is already in motion. Our Effluent Treatment Plant set a new standard for liquid waste circularity, recovering 90% of treated effluent as reusable water, but this is just one part of a broader journey. Across our network of specialist facilities, from our composting operations and recycling centres to our engineered landfills and alternative waste treatment sites, we are continuously pushing to improve how waste is managed, processed, and recovered.

New technologies, whether in the form of thermal desorption, mechanical pre-treatment, or alternative fuels, are being explored to support diversion and resource recovery. At our Refuse Derived Fuels Facility, for example, we are extracting value from previously non-recyclable materials to reduce reliance on landfill, while exploring partnerships that support material beneficiation and energy potential.

Our vision also includes expanding closed-loop systems where businesses are supported in taking greater ownership of their waste output , whether through pre-treatment, material recovery, or more sustainable disposal routes. Through this integrated approach, we aim not only to respond to today’s waste pressures, but to build the blueprint for a circular, waste-free tomorrow.

Turning Vision into Systems Change

Technology alone won’t transform waste into sustainability – policies, systems, and communities must evolve too. South Africa’s National Waste Management Strategy 2020 has laid out goals for circular economy growth, extended producer responsibility, and resource recovery. The opportunity is in bridging pilot technologies with national policy and community action to make zero waste a reality.

The journey toward zero waste-to-landfill is not a distant dream. It is a present-day responsibility with future-shaping potential. As we open the door to the realm of possibilities, we begin to see that transformation is not only necessary, but within reach. Interwaste’s work proves that change starts with bold infrastructure, strategic partnerships, and a willingness to challenge outdated systems.

But the future we imagine will not build itself. It depends on our collective ability to act with urgency and imagination. It’s about the choices we make now, to invest in circular thinking, to adopt better technologies, to reduce and rethink at every step of the value chain.

This spring let’s step forward with intention. Let’s refuse to accept waste as the end of the story and instead make it the beginning of something better. Because when we stop asking what if and start asking what next, we find the answers we need to build a cleaner, greener, waste-free world.

How the Waste Derived Fuel Facility is Converting Waste into Sustainable Energy

wont.socialise@gmail.com — Wed, 20 Aug 2025 07:15:55 +0000

The world is shifting toward sustainable energy solutions, and waste management plays a vital role in this transition. At Interwaste’s Waste Derived Fuel (WDF) Facility, located at Germiston Hub, we are at the forefront of this movement. By converting high-calorific waste into alternative fuel, we’re not only reducing carbon emissions but also providing industries with a cleaner energy source by reducing their fossil fuels consumption. This blog explores how the WDF Facility transforms waste into fuel and the environmental benefits it brings.

What is Waste Derived Fuel?

Waste Derived Fuel (WDF) refers to fuel produced from waste materials that are high in energy content. These materials can include certain types of industrial sludge, liquids, and hydrocarbon-rich waste. Instead of being disposed of in landfills, these waste streams are processed and converted into a specified fuel that can replace traditional fossil fuels such as coal. At our Germiston Hub, we specialize in producing this substitute fuel, which can be used by energy-intensive industries like cement manufacturing.

How the Waste Derived Fuel Process WorksThe process of converting waste into fuel at our Germiston facility involves several key steps:

Waste Selection: Only certain types of waste with a high calorific value are suitable for WDF production. We accept a variety of hydrocarbon sludges and liquids, particularly from sectors such as petrochemicals, which have high energy potential.
Pre-Treatment: The waste is tested and pre-treated to ensure it meets the required specifications for fuel production. Parameters such as calorific value, moisture content, elemental composition and flammability are carefully evaluated to determine the waste’s suitability for conversion.
Fuel Production: The selected waste is processed using advanced techniques to prepare a fuel that meets end-user specifications. This fuel is then used as a substitute for traditional fossil fuels in energy-intensive industries, significantly reducing carbon emissions.
Quality Control: The produced WDF is subject to rigorous quality control to ensure it meets the specific requirements of the industries that will use it. Factors such as combustion efficiency, energy output and potential impact on air emissions are tested to ensure the fuel performs effectively.

Waste Types Handled by the WDF Facility

At the Germiston Hub, we handle various types of waste, including:

Hydrocarbon sludges and liquids
Certain types of industrial waste with high calorific value
Qualifying waste from a variery of industry sectors, including the petrochemical industry.

These waste types, which would otherwise end up in landfills or incinerators, are transformed into a valuable energy resource that supports industries looking to reduce their environmental impact.

The Environmental Benefits of Waste Derived Fuel

One of the most significant advantages of WDF is its ability to reduce carbon emissions. By converting waste into fuel, we provide an alternative to coal and other fossil fuels, which are major contributors to greenhouse gas emissions. In addition to carbon reduction, WDF helps:

Reduce landfill usage: By diverting waste from landfills, we help minimize the potential environmental impact of waste disposal, including the generation of harmful gases like methane.
Promote resource recovery: Instead of managing these wastes to landfill, WDF turns it into a resource, supporting the principles of the circular economy.
Reduce reliance on traditional fossil fuels: As industries transition to more sustainable practices, WDF offers a viable solution for reducing reliance on fossil fuels.

Supporting the Circular Economy

The Waste Derived Fuel Facility at Germiston Hub plays a vital role in promoting the circular economy. By converting waste into a usable fuel, we close the loop on resource recovery. Instead of waste being discarded and new non-renewable raw materials being extracted, we use waste to create energy. This reduces the demand for non-renewable resources and helps industries adopt more sustainable practices.

Interwaste’s WDF Facility operates in compliance with applicable Acts and Regulations. Our processes are designed to minimize any related environmental impact, ensuring that all waste is handled safely and responsibly. We also work closely with industries that use WDF to ensure that they meet their sustainability goals and enviro-legal compliance, while adhering to strict safety standards.

Industries Benefiting from Waste Derived Fuel

WDF is an ideal energy solution for energy-intensive industries that are looking to reduce their carbon footprint through coal substitution. Industries that benefit from WDF include:

Cement manufacturing: Cement production is energy-intensive, the WDF offers an alternative to coal, helping this industry meet its sustainability targets.
Power generation: Some power plants use WDF as a substitute for fossil fuels, reducing their reliance on traditional fossil fuels.
Petrochemical industries: Petrochemical plants generate hydrocarbon-rich waste, which can be converted into fuel, providing an efficient, circular solution, by processing their waste into WDF thereby reducing their environmental impact through landfill avoidance.

As the demand for sustainable energy solutions grows, the Waste Derived Fuel Facility at Germiston Hub is leading the way in converting waste into alternative fuel. By transforming high-calorific waste into a substitute fuel, we’re helping industries reduce their carbon emissions and support the circular economy. If you’re looking for a cleaner, more sustainable energy solution, Interwaste’s WDF Facility is the answer.

Nurturing Nature Together: Celebrate World Nature Conservation Day

wont.socialise@gmail.com — Sat, 26 Jul 2025 20:00:14 +0000

World Nature Conservation Day, observed on the 28 of July each year, is more than a date on the calendar – it’s a reminder of the deep connection each of us shares with South Africa’s breathtaking landscapes, from fynbos and forests to wetlands and coastlines. As a globally recognised as 1 of 17 megadiverse country, our ecosystem is rich, fragile, and worth preserving.

Every river we swim in, every bird we watch, every tree we climb is a part of this legacy. That’s why it’s vital to honour and protect it – not just today, but every day.

Conservation Leaders We Stand With

SANBI – Guardians of Indigenous Flora

Through its national botanic gardens like Kirstenbosch and Harold Porter, SANBI showcases the beauty of our indigenous plants and educates citizens on ecological restoration. Their tree planting drives, community educational programs, and citizen-science projects are keeping traditional knowledge and habitats alive.

WWF South Africa – Protectors of Wild Places

From leading the WWF‑Mondi Wetlands Programme to safeguarding endangered species like the blue crane and African penguin, WWF’s work spans landscapes – wetlands, grasslands, oceans. It’s hands-on science, community engagement, and policy advocacy rolled into one.

These organisations don’t do their work for recognition, they do it because they care deeply about this country’s natural wealth. They plant, they research, they teach. And we all benefit.

Interwaste’s Community Commitment

We’re proud to be part of a movement larger than ourselves. Through our Act4Nature commitments (2023–2027), Interwaste supports conservation in meaningful ways – actions rooted in partnership, evidence, and local impact:

1. Restoring Nature at Klinkerstene

In collaboration with independent and SANBI ecologists, our Klinkerstene site received biodiversity assessments. The assessments will assist us in identifying various areas of improvement where we can restore and preserve the already existing fauna and flora on site. This includes the removal of invasive alien plant species, fostering pollinator pathways, and enhancing habitat zones – all contributing to the site’s long-term ecological resilience.

2. Biodiversity Spotlight: Germiston Hub

In 2023, we launched a biodiversity Hotspot at our Germiston Hub – an area that has been dedicated to the conservation and preservation of biodiversity within a heavy industrial area. Species monitoring, guided by biodiversity champions on-site, help identify numerous indigenous plants and animal species, reinforcing the idea that even high-traffic operational areas can support biodiversity when managed responsibly. The Germiston work forms part of our broader commitment to integrate conservation thinking across all Interwaste sites, not just in protected zones.

3. Depollution & Regeneration in Action

At our Leachate & Effluent Treatment Plant in Delmas, we cleanse and recycle millions of litres of industrial wastewater each month. That water is repurposed, not lost – supporting local ecosystems and preventing contaminants from reaching rivers and wetlands.

4. Circular Resource Practices

Every day, we convert non-recyclable waste into Refuse Derived Fuel (RDF) and alternative liquid fuels – showing how “waste” becomes opportunity. These energy solutions help reduce reliance on fossil fuels and support regional industries, proving that a circular economy isn’t just a concept – it’s real action.

How You Can Join the Journey

Whether you’re a student, teacher, business owner, or retiree, each of us can contribute:

Connect Locally: Visit a SANBI garden, walk nature trails, attend guided events – spend time where nature thrives.
Volunteer with Purpose: Join WWF or SANBI programmes – from coastal clean-ups to citizen-science plant monitoring.
Model Circular Living: Swap disposable items, start composting, and support products made through eco-conscious practices.
Stay Curious: Learn about the rare fynbos of Western Cape, the Knysna Forest elephants, or the wetlands at iSimangaliso. Share stories and spark change.
Champion Biodiversity: Ask local councils and employers to follow habitat-friendly practices and circular resource use – vote with your voice, your wallet, your time.

When we plant native shrubs at Klinkerstene, when we treat leachate water at Delmas, when we visit SANBI gardens or join WWF cleanups, we are doing more than checking a box. We are building community. We are connecting with something greater than ourselves. Today, on World Nature Conservation Day, let’s commit to that connection – not because it’s convenient, but because it’s essential.

From the water that sustains us, to the air we breathe, to the ecosystems that balance our world: it all begins with action. Interwaste is proud to walk this path – with you, with SANBI, with WWF, with South Africa.

Let’s protect what we love, together.

Serving Land and Life: Small Steps Toward Big Sustainability Goals

wont.socialise@gmail.com — Thu, 29 May 2025 20:00:56 +0000

Waste management doesn’t need grand gestures to create lasting change. Often, it’s the small, intentional actions – separating recyclables, reducing food waste, or supporting eco-friendly businesses – that create the biggest impacts. In South Africa, where waste management is still evolving, these small steps are essential to addressing environmental challenges while uplifting communities. By focusing on incremental progress, we can serve both land and life, laying the foundation for a healthier, more sustainable future.

A Legacy of Progress

South Africa has made significant progress in improving waste management systems, but many communities still face challenges. According to the Department of Forestry, Fisheries and the Environment (DFFE):“Although 61% of South African households had access to kerbside domestic waste collection services in 2007, this access remains highly skewed in favour of more affluent and urban communities. Inadequate waste services lead to unpleasant living conditions and a contaminated, unhealthy environment.”This disparity highlights the importance of small, targeted actions that can improve waste services for underserved communities while advancing broader sustainability goals.

Small Steps Driving Big Impacts

Organic Waste Composting in Cape Town
The Oribi Village Composting Initiative in Cape Town has transformed how local businesses manage organic waste. By partnering with restaurants and markets, the program diverts food waste from landfills and turns it into nutrient-rich compost for urban farming. This small, localized effort reduces methane emissions while supporting local food production.
Repair Cafés in Johannesburg
Repair cafés are popping up all over the world as community-led hubs where people can bring broken items to be fixed rather than discarded. These spaces promote a culture of reuse and repair, reducing waste and extending the life cycle of everyday products.
Community Recycling Hubs in Limpopo
In rural Limpopo, the WasteAid SA Recycling Project has introduced community recycling hubs where residents can drop off recyclables and receive incentives. This program empowers communities, reduces litter, and fosters economic opportunities through recycling.

Connecting Waste to Land and Life

The connection between waste management and broader environmental and social health is clear. Poorly managed waste affects soil fertility, biodiversity, and water quality – all critical to sustaining life. For example, polluted soil from illegal dumping sites limits agricultural productivity, impacting food security for vulnerable communities. Conversely, sustainable practices like composting restore soil health and promote biodiversity.

In KwaZulu-Natal, efforts to rehabilitate the Duzi Riverbanks have included community cleanups and waste education campaigns. These initiatives not only remove waste but also restore habitats for local wildlife, proving that small steps can lead to meaningful change.

Start Small, Think Big

Serving land and life starts with small, intentional steps. Whether it’s reducing your own waste, supporting local recycling initiatives, or participating in community cleanups, every action contributes to a healthier planet. Here are three simple ways to get started:

Reduce Food Waste: Plan meals and compost scraps to minimize waste.
Support Repair Initiatives: Fix broken items rather than replacing them.
Engage Locally: Participate in recycling or cleanup efforts in your community.

Small actions, when multiplied, create ripples that shape the future. By focusing on serving both land and life, South Africa is proving that incremental progress can have profound effects. Let’s continue to take small, intentional steps that protect our environment, empower communities, and inspire sustainable change.

Each of us has a role to play. Together, we can transform the way we manage waste and redefine our relationship with the land and the life it supports. Start small, think big, and make every action count.

Turning Waste Into Opportunity

How Klinkerstene Waste Park Ensures Safe and Sustainable Waste Disposal

wont.socialise@gmail.com — Thu, 20 Feb 2025 08:25:42 +0000

In the world of waste management, landfills often have a negative reputation, but they play a crucial role in safely containing and managing waste. At Klinkerstene Waste Park, the Landfill Facility is designed to meet stringent environmental regulations, ensuring that waste is disposed of responsibly and with minimal environmental impact. With advanced pre-treatment processes, we aim to reduce contamination risks while providing a safe disposal solution for various waste types.

The Role of a Landfill in Waste Management

A landfill is a carefully engineered facility where waste is isolated from the surrounding environment. Unlike traditional dumping grounds, modern landfills are designed to minimize the release of harmful substances into the air, water, and soil. At Klinkerstene Waste Park, our landfill adheres to strict regulatory standards, providing a safe solution for waste that cannot be recycled or treated by other means.

Waste Streams Handled by the Landfill Facility

Our facility accepts a variety of waste streams, including:

Type 0 – 1: High-risk hazardous waste that requires pre-treatment before disposal
Type 2 – 4: Lower-risk waste that can be disposed of directly

The landfill is specifically designed to handle these diverse waste types in a manner that prevents contamination and environmental harm. For high-risk waste, we apply pre-treatment techniques to immobilize hazardous substances before they are buried, ensuring that they do not leach into the surrounding environment.

Pre-Treatment Process at the Landfill

Before certain types of waste can be disposed of in the landfill, they must undergo pre-treatment. This process ensures that any hazardous substances are stabilized, reducing the risk of contamination. At Klinkerstene, we use various methods, including chemical and physical treatments, to immobilize contaminants such as heavy metals, preventing them from migrating into the soil or groundwater.

Environmental and Safety Regulations

Our staff undergoes continuous training to stay updated on the latest regulatory requirements and best practices in waste management.

How the Landfill Protects the Environment

Modern landfills like the one at Klinkerstene Waste Park are designed with multiple layers of protection to safeguard the environment:

Liners and covers: The landfill is lined with impermeable materials that prevent waste from seeping into the soil and groundwater. Once waste is buried, it is covered with a protective layer to prevent exposure to the elements.
Leachate collection systems: As waste decomposes, it produces a liquid called leachate. Our facility is equipped with systems that collect and treat leachate, ensuring that it does not contaminate surrounding water sources.

The Importance of Compliance in Landfill Operations

Landfills must meet strict compliance standards to ensure the safety of the environment and public health. At Klinkerstene, we prioritize compliance with both local and international regulations. This includes regular inspections, environmental monitoring, and the implementation of best practices to ensure that our landfill operates safely and efficiently.

While landfills are often seen as the final destination for waste, they can still play a role in the circular economy. By applying pre-treatment methods and recovering materials where possible, we minimize the volume of waste that ends up in the landfill. Additionally, the gas produced by decomposing waste can be captured and converted into energy, further contributing to resource recovery.

At Klinkerstene Waste Park, our Landfill Facility is more than just a place for waste disposal – it’s a carefully managed system designed to protect the environment and promote sustainability. By adhering to strict regulations, applying pre-treatment processes, and incorporating advanced containment systems, we ensure that waste is disposed of safely and responsibly.

Interwaste launches solution to improve South Africa’s water mix

South Africa is facing a major water crisis – with dry taps becoming a norm in big cities across the country. In fact, as an example, residents in Johannesburg have become all too familiar with planned water outages, as well as unplanned shutdowns – all in an attempt to preserve what little water is available and ration it accordingly between the 6 324 000 people who live in the city.

If we consider that Johannesburg is South Africa’s commercial capital, the impact has been far worse than residents lacking bath water. Businesses in water-reliant industries such as restaurants, gyms, car washes, and construction, amongst others, have also been severely impacted. The lack of water supply has led to businesses going for hours and sometimes days without water and operating for fewer hours – generating less income and creating a knock-on effect in terms of letting staff go, compromised hygiene and increased health risk.

The economic disruption is undeniable – calling for urgent and sustainable solutions to the water crisis.

So, where do we begin?

The development of these solutions begins with identifying the causes.

Research has revealed that amongst other reasons, inefficient water management is one of the main causes of water scarcity in the country; this speaks to the lack of water conservation infrastructure. The preservation of water through reuse, and waste treatment has been neglected for far too long – with water being used irresponsibly across both the public and private sectors.

A proactive approach to water preservation

To drive innovative ways to support South Africa’s water conservation requirements, as well as address the dire water shortage facing the country, Interwaste developed a sustainable solution – the newly launched Leachate and Effluent Treatment Plant. The plant is capable of treating approximately 43 million Liters of water per year, – recovering 80 to 90% of it into clean water. Designed with sustainability in mind, the plant’s circular approach means that some of this water is reused directly on site, reducing the consumption of precious natural resources and, in turn, mitigating the environmental risks posed by liquid waste while reducing the pressure on our water supply.

As the first environmentally responsible waste treatment facility in South Africa, the plant uses state of the art technologies and complies with stringent quality standards. In addition to the minimal waste generation, Interwaste uses chemicals responsibly, further reaffirming the organisation’s belief in sustainability and the responsible use of resources.

The role of emerging technology in addressing food waste.

16 October marks World Food Day – a day set to raise awareness about the importance of sustainable food systems and combating hunger worldwide.

According to an article published in Scientific American, the global food system contributes to around a third of human-generated greenhouse gas emissions. However, what has never been clear is how much of this is due to lost or wasted food. While a further article reveals that methane, from landfills, produced by the global food supply, is much more powerful at warming the planet than carbon dioxide itself – which is a sobering thought.

In a nutshell, food waste really does have a negative impact on the environment and society. The good news though, is that this waste can be managed effectively, not only from a household perspective, but right across the food supply chain.

The truth about food waste

There is a common misconception that food waste is only leftover food that is discarded by households. However, food waste occurs from the moment food is farmed all the way through to retail stores and ultimately into your homes. Not only does it occur at the production level due to several factors, including climate change, soil quality, diseases and/or lack of labour, but given that retailers place a premium on quality, produce that does not meet their quality standards can be rejected and thus, wasted. As a result, landfills are significantly impacted by food waste that was never actually consumed postproduction.

Considering the magnitude of the food waste challenge in South Africa (it is estimated that 30% of all food produced is wasted), addressing it goes beyond just households – and means that retailers, restaurants, and the agricultural industry at large need to become more actively involved in the reduction of food waste. While sustainability policies are helping curb this challenge – especially from a business perspective – there is a pressing need for solutions that can help these industries tackle food waste, to have a measurable impact on our food system and the environment.

The role of emerging technology

Technology and innovation play an important role in waste reduction and beneficiation by not only giving us new methods to manage waste more sustainably – especially from a supply chain perspective, but given the scale of waste these innovations, also include aspects like using this waste as a secondary resource. When considering food or organic waste, processes such as composting and anaerobic digestion are able to re-purpose this waste for another use, such as soil regeneration or energy.

Anaerobic digestion is a process by which biogas is created through naturally occurring bacterial processes. This gas is harnessed and used to generate electricity. Anaerobic digestion is an established process which requires specific expertise and technology, but essentially it reduces the amount of organic waste going to landfill, as well as a decrease in the emission of harmful greenhouse gases.

Furthermore, the platform can act as an on-site model that ensures that waste is managed immediately, as it is generated, and is then disposed of in hygienic and compliant manner.

So, in order to achieve our zero waste to landfill goal as a country, we all need to take part in making a change. Start with small changes in your purchasing habits, but in instances where food waste cannot be avoided, consider recycling that into compost as an example, or examine various other options within the waste management segment that could work for you and/or your business.

This World Food Day, think about your food waste – how you manage it – don’t just throw it away – it can be used and benefit the environment and all mankind.
