The main objective of this project is to create a pilot plant for the total elimination of poultry manure. The project, called Chimera, was developed by Tre P Engineering, chosen by the European Commission as part of the Life program, a program which since 1992 has been co-financing “green” projects proposed by member countries.

Process poultry droppings, removing pollution from poultry farms.

The ambition of the creators of Chimera has a double value: that of transforming waste into a resource and that of eliminating a major source of environmental pollution. A kind of throwback to the past which, however, combines with an innovative proposal aimed at creating sustainable energy.

The environmental burden of poultry droppings.

The elimination of faeces in EU countries would have a huge impact. We are talking about 25 million tonnes of greenhouse gases per year, 0.48 million tonnes of ammonia and 100,000 tonnes of heavy metals. The environmental impact of manure transport is not included. Disposal costs are between 10 and 22 euros per tonne, which represents a total of around 2 billion euros per year for the 152 million tonnes of manure produced.

Rosalino Usci, co-CEO of 3P Engineering explains:

If chimera were to become a norm in poultry farms, contamination from manure would be virtually zero, as would most of the problems associated with disposal costs and odors caused by fecal matter.

Farms could also become self-sufficient in energy, and fertilizers would ensure abundant food production for chickens.

How Chimera Works.

The idea is very simple: poultry droppings are used to make high-quality fertilizer and, at the same time, to produce energy, heat and electricity, useful for the livelihood of the farm. It is a small industrial facility that operates on a continuous cycle.

Chicken manure is transported on a belt to the power station. At the end of the process, ash is obtained which, together with the smoke, passes through two water purifiers, devices that reduce the concentration of polluting substances in industrial waste.

Here, the substances come in the form of sludge which is then passed to a centrifuge, capable of separating the liquid part from the solid. The solid part will be the fertilizer, a product rich in nitrogen, phosphorus and potassium.

The heat generated during combustion is in turn converted into electrical energy. The water used for the treatment of poultry excrement is fully reused to hydrate the ash and reduce polluting emissions from the smoke.

The future of the project.

The first two prototypes will be produced in Italy, in the Marche region, while the pilot plant will be launched at the Renders & Renders factory, in the Noord-Brabant region, the Netherlands. The latter will remove at least 1,500 tonnes of manure per year and must be able to work at least 6,053 hours per year, producing 4.5 GWh of heat and electricity and 260 to 320 tonnes of fertilizer. Chimera is a project that can be replicated in other contexts of biowaste production.
