GreenCape, in partnership with the City of Cape Town, has published a new case study titled: Nutrient Upcycling: Spent Brewery Grain to Insect Protein and More.

Black Soldier Fly (BSF) farming leverages the insatiable appetite of BSF larvae to convert low grade organics into high value animal feed and related products, for which the global demand is increasing. These products have various applications, notably in animal feed and pet food, but also in crop production, cosmetics, and pharmaceuticals, and more applications are continually being investigated, including human food.

The number of companies in South Africa that are utilising BSF farming is increasing. Maltento is one of these Cape Town based businesses pioneering BSF farming technology. Maltento has developed a circular solution that upcycles low-value organic by-products into high value products that are good for people, good for the planet, and good for business.

This case study is written for commercial organic waste generators along the food value chain, a value chain known for considerable loss and wastage, to illustrate how circularity is a useful lens through which to imbed resilience in the food supply chain.

Upcycling organic by-products is one of many circularity activities the food and beverage sector can use to alleviate pressures on the overall system. Organic waste beneficiation will reduce landfill disposal liabilities and strengthen competitiveness, which in turn contributes to building more resilient businesses and more resilient cities

The case study discusses:

  • Upcycling organic by-products into high value products;
  • Localising protein feed production; and
  • Facilitating a resilient food system.

It is written for:

  • Businesses disposing of food waste to landfill;
  • Animal feed brands / producers; and
  • Food brands looking to strengthen supply chain resilience.
