What is this tool intended for?

The BUGS Africa Operators Toolkit is Designed to help BSF biowaste conversion operators, entrepreneurs, farmers, investors, and NGOs plan, set up, and run BSF waste processing systems at simplified small to medium scale. It specifically targets non-industrialised, mainly labour-based operations suited to low- and middle-income country contexts, particularly in Africa. The toolkit aims to fill a gap in accessible, consolidated guidance for BSF operators, addressing barriers such as dispersed knowledge, lack of documented procedures, and limited information on markets, regulations, and Business models.

How does this tool work?

The toolkit is a downloadable PDF manual structured into seven thematic chapters. It uses a practical, operator-oriented approach and draws on field experience, peer-reviewed literature, and established BSF guidance documents. The chapters cover:

•        Elements of a BSF biowaste conversion facility (fly reproduction unit, grow-out unit, substrate sourcing, product treatment, sales, hygiene, and BSF welfare)

•        Key performance indicators (KPIs) for monitoring reproduction and grow-out unit performance

•        Operational and production models (scale, technology level, location, and four distinct Business models)

•        Standard operating procedures (SOPs) for both simplified small-scale SIMBA operations and medium-scale step-by-step operations

•        Planning and scaling guidance, including feasibility Assessment, financial modelling, pilot Design, and overcoming common challenges

•        Troubleshooting approaches for identifying and resolving operational problems

The toolkit is an analogue (paper/PDF) resource, but it includes hyperlinks to companion digital tools such as the BSFL Substrate Navigator, GHG emission calculators (Excel-based), and cost-revenue models (Excel-based) that can be downloaded separately.

Who might use this tool and with which types of stakeholders?

The toolkit is primarily intended for:

•        BSF operators and farmers already running or planning to start BSF biowaste conversion activities at small or medium scale

•        Entrepreneurs and start-ups exploring insect farming as a business in Africa and other low- and middle-income country contexts

•        NGOs and development organisations supporting sustainable waste management, food systems, or circular economy projects

•        Investors assessing the feasibility and viability of BSF ventures

•        Extension workers and trainers supporting farmers or waste management operators

It supports engagement with stakeholders including municipal waste management authorities, agribusinesses sourcing sustainable Feed or Fertilizer, local markets for BSF-derived products (aquaculture, poultry, crop farmers), and carbon credit trading partners.

What stages of a process can this tool support?

The toolkit supports multiple stages of BSF waste processing project planning and implementation:

•        Feasibility Assessment: Evaluating local conditions (climate, substrate availability, market, regulation) before establishing a facility

•        Business planning: Selecting a production model (SIMBA, centralised, decentralised, or hub-and-spoke) and business model (Feed/frass, waste management/carbon credits, egg/larvae supply, niche products)

•        Facility Design and setup: Understanding the technical elements of a BSF facility and dimensioning grow-out containers and larvae densities

•        Daily operations: Following standard operating procedures for reproduction and grow-out units

•        Monitoring and performance optimisation: Tracking KPIs such as bioconversion rate, waste reduction rate, and reproduction performance indicators

•        Financial planning: Using linked Excel tools for cost-revenue modelling and GHG emissions estimation

•        Troubleshooting and learning: Identifying deviations in operations and implementing corrective measures

What skills, capabilities and resources are required to use this tool?

The toolkit is Designed to be accessible without advanced technical training. Users with a background in agriculture, animal husbandry, or waste management will find the content particularly intuitive. Specific requirements include:

•        Basic literacy and ability to read a practical operational manual (available in PDF)

•        Familiarity with organic waste types and basic concepts of animal rearing or farming

•        Access to a device and internet connection to download the toolkit and access the companion digital tools (BSFL Substrate Navigator, Excel calculators)

•        For financial and GHG modelling: basic proficiency with Microsoft Excel or similar spreadsheet Software

No specialist entomological knowledge is required. Operators from agricultural backgrounds have been found to adapt quickly to BSF operations. Training opportunities are referenced in the toolkit, including online communities of practice such as the BSF-Africa WhatsApp community.

Where can this tool be used?

The toolkit is primarily Designed for use in tropical and sub-tropical regions where ambient temperatures (25–32°C) and humidity levels (60–80%) are naturally suitable for BSF biowaste conversion. This includes much of Sub-Saharan Africa, South and Southeast Asia, and Latin America. However, the guidance is applicable in any context where BSF operations are planned, including areas requiring some climate control infrastructure.

The toolkit is particularly suited to:

•        Urban and peri-urban settings where organic waste streams (market waste, food waste, agricultural by-products) are available

•        Low- and middle-income country contexts where labour-based, low-tech approaches are preferred

•        Farm-based settings where BSF larvae and frass can be self-used as Feed and Fertilizer

•        Community-level or decentralized waste management programmes

Case examples of where this tool has been used

The toolkit was developed in the framework of the BUGS-AFRICA project, which includes BSF implementation activities and field experience across multiple African countries. Photographic and operational examples referenced in the toolkit include:

•        BSF fly reproduction units (love cages) at a facility in Kenya

•        Nursery containers for young larvae production in Uganda

•        Bioponds in a grow-out facility in Côte d'Ivoire

•        Stacked crate systems fed with organic waste in Indonesia and the Philippines

The SIMBA (Simplified BSF Approach) system described in the toolkit has been tested and applied in community and farm-scale settings across Africa, with linked SOPs available for free download. The toolkit's companion GHG calculator and cost-revenue model have been used by project partners to assess emissions savings and financial viability of small-scale BSF operations.
