Circular Bioeconomy and Waste Valorisation
A unifying theme across my research is the role of insects in closing nutrient loops within agri-food systems. I examine how organic residues can be transformed into valuable insect biomass, while assessing: bioconversion efficiency and production performance; environmental trade-offs and sustainability outcomes; opportunities for integrating insect farming into existing value chains. This research supports the development of waste-to-feed and waste-to-value systems that align animal production with circular bioeconomy principles.I study how insect oils interact with animal metabolism and physiology, with particular attention to: nutrient utilisation and energy metabolism; gut health and immune-related responses; implications for feed formulation and product quality. This research direction contributes to the growing interest in functional feeds and sustainable alternatives to conventional vegetable oils in animal nutrition.
1. What it means for feed producers
- Turning waste into raw materials: Organic residues (farm waste, food waste, agro-byproducts) can be converted into insect biomass, creating a low-cost, sustainable feed ingredient supply.
- Cost efficiency & margins: Reduced dependence on expensive imported inputs like soybean meal and vegetable oils improves profitability.
- Integrated production systems: Feed producers can vertically integrate insect farming into their operations, controlling both input supply and quality.
- Dual-value products: Producers can generate both insect protein (meal) and insect oils (functional lipids) for advanced feed formulations.
- Sustainability branding: Ability to market feeds as part of a circular economy, appealing to environmentally conscious markets and regulators.
- Innovation in formulation: Combining waste-derived insect inputs with functional benefits (gut health, immunity) creates next-generation feed products.
2. Key takeaways for farmers
- Waste becomes value: Farm and household organic waste can be converted into feed through insect farming, reducing disposal problems.
- Lower feeding costs: Access to locally produced insect-based feeds reduces reliance on expensive commercial feeds.
- Improved productivity: Functional benefits (better digestion, immunity, energy use) support healthier and more productive animals.
- Sustainable farming systems: Integrating insects helps farmers adopt closed-loop systems—less waste, more efficiency.
- Additional income streams: Farmers can sell insects, larvae, or processed products to feed producers.
- Resilience: Reduced exposure to global feed price fluctuations and supply chain disruptions.
3. Policy & industry relevance
- Waste management solutions: Supports policies that promote organic waste recycling into productive use rather than landfill disposal.
- Circular bioeconomy development: Aligns with national and global strategies for resource efficiency and sustainable agriculture.
- Environmental impact reduction: Lower greenhouse gas emissions, reduced land use, and less pressure on natural resources compared to conventional feed systems.
- Regulatory frameworks needed: Clear guidelines on waste substrates, insect rearing standards, and feed safety are essential.
- Value chain integration: Encourages collaboration between agriculture, waste management, and feed industries.
- Economic growth & jobs: Creates opportunities for SMEs, startups, and youth in insect farming, processing, and feed manufacturing.
- Food system resilience: Strengthens local production systems, especially in regions like Africa where feed and waste challenges are significant.
