Challenges

  1. If mismanaged, conventional organic waste treatment methods can emit methane and CO₂, contributing to the climate crisis.
  2. Mismanaged organic waste releases odors and helps rodents and insects multiply and spread diseases.
  3. If organic waste is not collected separately, it often ends up in the residual waste container together with other waste. As a result, the recycling and composting potential of organic waste remains untapped, resulting in an increased amount of waste being sent to landfills.

Our Solution

Implemented by the ACEN Foundation, Trinomics, Eclose, and Eawag, the project develops a methodology to assess the feasibility of BSF initiatives to be piloted in the target countries. It also seeks to capture best practices and foster collaboration among stakeholders, mainstreaming BSF farming into waste management, agriculture, and climate-oriented strategies. The project can also contribute to capacity development, job creation and technology transfer.

Workshops held in 2024 in each country brought together stakeholders to discuss opportunities, explore existing policies, and address technical gaps. The sessions also explored how BSF technology could complement existing composting initiatives, and manage waste from food processing, and design sustainable business models. The multiyear project aims to lay the groundwork for future BSF initiatives and create favourable economic and institutional conditions for long-term success.

Black Soldier Fly Technology (BSF)

The Black Soldier Fly (BSF), Hermetia illucens, is recognized for its ability to convert organic waste into protein- and fat-rich feed for cattle, pigs, chicken, fish, and pets. The fly larvae are fed with organic waste, reducing its amount by 50–80%. Larvae can be harvested after about 14 days with a waste-to-biomass conversion rate of up to 20% (on a total solid basis). The larvae be processed and used as animal feed, while the remaining residue can be composted and used as fertilizer (frass) and soil conditioner.
