Pyrolysis plant - from waste to energy.

Pyrolysis Plant
At Green Solution House we produce energy from food leftovers. All food scraps and organic material from the main building is fed into our own stationary pyrolysis plant, that likes all carbon based waste. The material is first dried and ground, then all the oxygen is removed. The pyrolysis process heats the waste, breaks it down, and then produces natural gas and char. A cyclone separates the gas, producing biochar, that sequesters carbon in a stable state. Biochar is valuable as an additive for the gardens as it improves soil health and water retention. The gas is combusted in a Combined Heat and Power (CHP) engine generating heat and electricity to be used in the building. Excess hot water is stored onsite in a swimming pool, repurposed as an energy storage system. The pyrolysis plant is self-supporting, and only requires a small amount of energy to start up.

Green Solution House will release approximately 12.4 tons of dry material to the Pyrolysis Plant yearly. The plant has the capacity to process 1 ton of dry material over 6 hours which produces an output of 180 m3 of gas, 360 kWh of ectricity, and 100 kg of biochar.
