Monthyon: Shrimp farming using waste incineration heat

What if you could soon taste the shrimp created thanks to the heat network produced by the waste treatment center? This could be possible in a few years thanks to the process implemented by start-up Lisaqua.

On Tuesday, April 19, 2022, Véolia and Smiom du Nord Seine-et-Marne selected this young company to carry out a energy recovery project at the Monthyon Energy Recovery Facility.

The heat generated by incinerating household waste will heat the water in the ponds where the shrimp will grow. This process is the first in France.

The project is still in an embryonic stage and a study of viability still needs to be done. But if it’s feasible, work can start in 2024.

In April 2021, Smiom and Véolia launched a call for demonstrations aimed at promoters of agricultural or industrial projects with values ecological. After a long selection process, the startup Lisaqua was chosen.

Based near Nantes, in Saint-Herblain, Lisaqua is a company focused on shrimp farming with a low environmental impact. Lisaqua breeding tanks will work in symbiosis with the energy recovery unit (EUV) in Monthyon. The farm will be attached to the Integrated Treatment Center (CTI) already installed.

An important environmental issue

“The idea behind calling the protests was to have someone who could benefit from UVE’s residual heat. With the current geopolitical context and gas prices, we have to find other alternatives”, explains Michelle Brun, director of Smiom du Nord Seine-et-Marne. “Lisaqua is a start-up with great values ​​that invests in sustainable development and recovered energy”.

Founded in 2018, Lisaqua aims to “make aquaculture healthier and more sustainable”. In Saint-Herblain (Loire-Atlantique), the company has already set up a breeding base where it intends to produce 10 tons of shrimp.

“Traditional shrimp farming is done far from France because they have to live at a temperature around 28°C and they are full of antibiotics, which contributes to the destruction of the seabed and mangroves”, explains Gabriel Boneu, president from Lisaqua. “We have developed a breeding site without antibiotics, without foreign imports and without polluting discharges: triple zero”.

Shrimp waste will be recycled to simultaneously create marine invertebrates that will serve as animal feed. The process will be closed circuit production without pollutants or discharges.

By recovering the heat already produced by the CIT, Lisaqua will be able to raise more than 500 tons of shrimp a year at the Monthyon site.

a local interest

When the feasibility study and the works are concluded, the breeder will create between 40 and 50 jobs in the sector in various scenarios. Work, commercial and scientific jobs will make the site an important center of commerce and research in Ile-de-France.

France imported 80,000 tonnes of tropical shrimp a year and the farm will help reduce that rate because it will be able to meet the needs of the entire Ile-de-France when it becomes operational in 2025.

“We very much hope that it will be completed, in the interests of all parties involved, but also in the interests of the territory and with regard to its environmental and social impact” concludes Jean-François Léger, President of the Smith of the North Seine-et-Marne .
