Industrial symbiosis is when different industries work together to use resources better, create less waste, and be more sustainable. This is important in making insect protein, a new and eco-friendly food source. Let’s look at how this collaboration helps produce insect protein, its benefits, and its potential to change the food industry.
Why Insect Protein?
Insect protein is a sustainable alternative to traditional animal protein. Insects are efficient at turning feed into protein, need less water and land, and produce fewer greenhouse gases than livestock. With the rising global demand for protein, insect farming can help meet this need with less environmental impact.
What is Industrial Symbiosis?
Industrial symbiosis is when separate industries share resources like materials, energy, water, and by-products. The idea is to make waste from one process useful for another, reducing overall waste and improving efficiency. This is part of the circular economy, which aims to keep resources in use as long as possible.
How It Works in Insect Protein Production
Using Organic Waste:
- Insect farms can use organic waste from food processing, agriculture, and other industries as feed. This is a cheap feed source and helps manage waste that would otherwise go to landfills or incinerators.
- Feedstock is moved via pipelines instead of trucks, saving around 12,000 truck trips a year and eliminating the need to dry by-products before transport.
- Food processing plants can send vegetable peels, fruit scraps, and other organic waste to insect farms. These materials are great for rearing insects like black soldier flies and mealworms.
Energy and Heat Exchange:
- Insect farming needs specific temperature and humidity levels. Industries with extra heat or energy, like power plants, can supply this to insect farms.
- This reduces energy costs for insect farmers and helps other industries manage their excess energy.
Nutrient Recycling:
- By-products of insect farming, like frass (insect excrement), are rich in nutrients and can be used as fertilizer for crops. This recycles nutrients back into the soil, promoting sustainable agriculture.
- Farms can use frass to improve soil health and reduce the need for chemical fertilizers.
Water Management:
- Water used in insect farming can be treated and reused in other processes. Industries with water-intensive processes can collaborate with insect farms to recycle and treat water, optimizing water use and reducing waste.

Benefits of This Collaboration
Environmental Sustainability:
- Reduces waste and greenhouse gas emissions.
- Promotes recycling of nutrients and organic materials.
- Decreases reliance on limited resources like land and water.
Economic Efficiency:
- Lowers production costs by using waste materials as feed.
- Reduces energy and water costs through shared resources.
- Creates new revenue streams for industries supplying waste materials.
Enhanced Collaboration:
- Fosters innovation and collaboration between different sectors.
- Encourages the development of integrated systems and sustainable practices.
Looking Ahead
The collaboration of different industries in making insect protein is just beginning but has great potential. As more industries see the benefits of working together, we can expect more innovative and sustainable systems. Governments and policymakers can support these initiatives by providing incentives for industries to adopt symbiotic practices.
In conclusion, industrial symbiosis can make insect protein production more sustainable and efficient. By using the resources and by-products of various industries, we can create a more resilient and eco-friendly food system. Working together will be key to tackling global challenges and achieving a sustainable future.
