Turning Waste Into Opportunity

Written by Natasha Edwards | 20 April 2025

Every year on the 22nd of, Earth Day serves as a global reminder of the urgent need to protect our environment. With landfills nearing capacity, pollution rising, and climate change accelerating, sustainable waste management has never been more crucial. This year’s theme, “Planet vs. Plastics,” highlights the need to tackle plastic waste and transition towards circular economy models. At Interwaste, we play a critical role in this shift by reducing landfill dependency, maximizing resource recovery, and pioneering alternative waste treatment technologies.

 

The Environmental Challenge of Plastic Waste

Globally, over 400 million tonnes of plastic waste are produced annually, yet less than 12% is estimated to have been effectively recycled. South Africa alone generates 2.4 million tonnes of plastic waste each year, much of which ends up in landfills, rivers, and oceans. The environmental cost of plastic pollution includes:

  • Severe harm to marine and terrestrial ecosystems
  • Microplastic contamination in water and food chains
  • Significant carbon emissions from plastic production and disposal

Without intervention, plastic production is expected to double by 2050, further straining ecosystems. The only solution is a radical transformation in waste management, material use, and resource recovery – something Interwaste is actively driving.

 

How We are Leading the Change

Reducing Plastic Waste Through Recycling and Recovery

Encouraging the diversion of plastic waste from landfills and reintegrating it into new production cycles. Working alongside our clients, we strive to separate waste as early as possible in the supply chain, reducing contamination and increasing its potential to be reused in the same or alternative processes.

 

Advancing Alternative Waste Treatment Technologies

Strategic investment in technologies that support the reutilization of non-recyclables or hazardous waste streams. Through the development of solutions like these, we effectively address the challenges that these waste streams pose to our planet. This includes:

  • Contaminant immobilisation stabilises hazardous waste, preventing soil and water contamination.
  • Effluent treatment processes millions of litres of industrial wastewater annually, ensuring compliance with environmental standards.
  • Waste-to-energy technologies convert non-recyclable wastes into alternative fuel sources, helping industries reduce reliance on fossil fuels. 

Promoting a Circular Economy

The circular economy eliminates waste by keeping materials in use for as long as possible. At Interwaste, we:

  • Develop closed-loop recycling systems, ensuring high-value materials are continuously reused.
  • Partner with industries to redesign waste processes and increase sustainability.
  • Invest in innovative recovery technologies that create value from waste.

By ensuring waste is reintegrated into supply chains rather than discarded, we support both environmental conservation and economic resilience.

 

Environmental protection is not the responsibility of one organization alone—it requires collaboration among businesses, industries, and communities. Small actions—such as reducing plastic use, supporting recycling efforts, and choosing sustainable alternatives – can have a profound impact on the future of our planet.

 

At Interwaste, we remain committed to driving change through innovation, responsible waste management, and strategic industry partnerships. By transforming waste into opportunity, we are actively shaping a more sustainable, resilient, and waste-free future.
