Opportunities for value addition to selected Western Cape organic waste streams

This report by GreenCape identifies business opportunities for adding value to lignocellulosic biomass waste streams in the Western Cape, South Africa. It analyzes five primary streams: invasive alien vegetation (IAV), industrial composite wood materials, pallets, paper sludge, and green waste, evaluating their current utilization, logistical challenges, and potential for transformation into higher-value products or energy.

• Approximately 700,000 tonnes of invasive alien vegetation (IAV) biomass are available in the Breede and Berg River catchment areas of the Western Cape. However, much of this is not easily accessible, and the high cost of labor for logistics often results in low or negative margins for beneficiation.
• IAV is considered an unsustainable resource for long-term investment, with the current supply estimated to last only ten years. This necessitates that any technology investment considers a ten-year lifespan.
• Industrial composite wood waste—including medium density fibre-board (MDF), chipboard, and plywood—is generated at a rate of 3,000 to 5,000 tonnes annually in the Western Cape, largely concentrated in the Northern Suburbs of the City of Cape Town. These materials often contain harmful chemicals, such as polyvinyl chloride (PVC) and formaldehyde, which complicate disposal and energy recovery due to the release of chlorine and carcinogens during combustion.
• Paper sludge, a fibrous material with high water content from paper and cardboard manufacturers, is currently fully utilized by clay brick manufacturers, with demand exceeding supply. This leaves little opportunity for further valorization unless new, higher-value uses are developed.
• Municipal green waste (tree off-cuts, leaves, and grass clippings) is primarily managed through composting. Reliance Compost holds the largest share of this market due to its logistics fleet and large-scale composting facility on the outskirts of the City of Cape Town.
• The Toronto Group has successfully secured funding for IAV beneficiation by ensuring security of supply through land procurement near clearing operations and securing demand via the export of charcoal to Europe.
