Discovered the remains of peppers and tomatoes improve biogas production.

The pepper increases by 44% methane production compared with digests only with purines; tomato in a 41%; a peach 28%; and persimmon no difference. These are the main findings of research by a team from the Polytechnic University of Valencia. The researchers note that in a year you can get results-scale and apply technology in biogas plants.

Tests have entails combining purines pig farms with agricultural byproducts (Waste pepper, tomato, peach and persimmon) for their potential to produce biogas and seek optimal combination of both substrates.

The project was funded by the Foundation Agroalimed, the Ministry of Agriculture, Fisheries and Food of the Generalitat Valenciana, and seeks to provide a more sustainable to overproduction of purines output and low profitability and environmental suitability for use as nutrients in agricultural land.

researcher, Verónica mash, He explains that "purines produce energy, but little and, Therefore, It is not profitable for the farmer to bear the cost of a biogas plant. For this reason, We have combined the purines with destríos (waste) of some horticultural products and fruit areas of Valencia where pig farms are located, to increase the level of methane in slurry and, in this way, producing biogas profitably ".

The researchers note that in one year can obtain full-scale results and could already be applied in centralized biogas plants. Managers of these plants could be both companies, agricultural and livestock cooperatives and even municipalities own areas where livestock is concentrated in Valencia.

Companies based in the Canary Islands already been interested in the results of research and study the feasibility of its implementation, savvy contributions remains of the two main vegetables produced both Gran Canaria and Tenerife.
