Do you know that one tone of chicken dung produces 130 m3 of biogas ??

I bet that not everybody know that..haha..hmm..that’s a fantastic fact right??

Chicken is thing that almost every day we eat..in McD of KFC, which is not very good.. hmm..now, chicken can make another product that help our living society to get more renewable energy…the energy comes from chicken’s dung.. imagine how many chicken farm in the world and how many dung that the farm produce..

Now,how can chicken dung which is just waste can produce biogas..here’s the process..enjoy it!

Chicken dung needs 1 year of storage in order to be applied as fertilizer. After treatment in biogas plant it is applicable without need for storage that makes possible to avoid its clutter in lagoons. In untreated state chicken dung has pungent odour caused by high ammonia content. After treatment in biogas plant ammonia concentration is considerably reduced that effects the odour.

Chicken dung drying and granulation are very energy consumptive that increase fertilizer net cost. Drying and granulating farm facility can be used for fermented biomass processing and fueled by biogas instead of natural gas.

By recycling chicken dung in biogas plant you get gas, electricity, heat and high quality fertilizer. Produced energy will be sufficient to provide poultry-houses, drying and granulating equipment with energy sources.

In anaerobically treated biomass nitrogen preserved in plant accessible ammonia form. One tone of solid bio-fertilizer contains 15-30 kg and liquid fraction 3-7 kg of ammonia nitrogen. Untreated chicken dung contains pathogenic microflora. After biogas plant treatment only active microflora present in biomass that stimulates soil microbiological processes. In the process of broiler breeding different types of litter are used. Mixture of dung and litter is not highly gas productive but also can be used as biogas plant raw material.

Peculiarities of poultry farm biogas plant

Main differences of chicken dung from other biogas raw materials are: 1) high protein content, which is nitrogen source 2) biomass humidity. That is why special technology for chicken dung should be used to be compared to cattle manure. Two stage technology. After receiving tank suited for 1-2 days storage capacity, biomass is pumped to hydrolysis bioreactor with 8-10 days retention time and special temperature, humidity and pH conditions. From hydrolysis reactor biomass is fed with certain proportions to bioreactor which is very important for bacterial balance. Biogas collected to outer gasholders made of durable and tensile material.

As a rule poultry farms require electricity and gas. With that purpose biogas plant can be equipped with co-generation unit and gas treatment system. Co-generation unit made in container and includes fuel regulation and feeding system, cooling system, automatic control unit.

Gas treatment system is also containerized and equipped with gas pressure regulating system, cooling system, automatic control unit, and methane storage tank.
