Management of wastewater and organic waste with the use of insects

We transform wastewater and organic waste into sustainable products using insects.

 

In Mexico, it is estimated that 60% of domestic and agri-food wastewater is released to aquatic bodies without any treatment, while 30% of all food is wasted. Without a doubt, this problem poses several problems to the environment and public health.

 

The traditional solution for both problems, anaerobic decomposition through biodigesters, septic tanks and hermetic fermenters, has proven to be inefficient, dangerous and even counterproductive, since the methane produced, a smothering greenhouse gas, regularly escapes into the atmosphere while the liquid waste called biodigestado or biol, often ends up contaminating aquifers. However, in CPlantae we have developed an innovative method of supra-recycling (upcycling) that takes advantage of the metabolism of two insects: the red worm and the black soldier fly.

Two endemic insects from America, the red worm (Eisenia foetida) and the black soldier fly (Hermetia illucens) are able to feed on organic waste and biodegradable wastewater, converting them into tissues rich in protein and fats, a process optimized over millions of years. evolution. Instead of degrading pollutants, we create more complex and valuable products and, in passing, we treat wastewater.

Our innovative wastewater and nutrient system optimizes the productivity of these two insects by imitating a rain forest ecosystem in a container, generating three outputs:

 

-Larvas fly and worms: which can be used commercially as a food supplement of animals rich in protein and fat. One kilo of these insects can reach a market value of 40 USD.

 

-Fertilizer (humus): the breeding of these insects generates excrement as a by-product, which is also marketable. Humus improves the health of crops by providing micronutrients, promoting a healthy biota and conferring the effects of natural pesticides.

 

- Clean water: water is received by gravity from its origin and is conducted to the tank where it percolates through this ecosystem. Then, the earthworms and fly larvae are responsible for processing the fecal solids and organic residues from the kitchen retained to convert them into humus, water vapor and carbon dioxide. The outgoing water has 95% less pathogens and a better quality compared to a septic tank and biodigesters, ready to be polished, infiltrated or reused for irrigation.

Our system, in patent process, has been successfully replicated in 4 states of Mexico: Tlaxcala, Puebla, Chiapas and Quintana Roo. soldier fly (Hermetia illucens) are able to feed on organic waste and biodegradable wastewater, converting them into tissues rich in protein and fats, a process optimized over millions of years. evolution. Instead of degrading pollutants, we create more complex and valuable products and, in passing, we treat wastewater.
