Green and Low-Carbon Biomass Energy Base

Currently the project utilizes the direct combustion technology from agriculture, forestry and animal by-products which generates large quantities of combustion smoke.  After the smoke has been cleared of dust and SO2 through air purification equipment, the remaining clean smoke contains 9% of CO2 and nitrogen oxides per cubic meter.  This smoke contains excellent nutrients for the successful growth of spirulina. 

The main carbon source of traditional spirulina farming is from baking soda (NaHCO3) with general farming requiring eight tons of baking soda.  If the baking soda is replaced with CO2 in the power generation smoke, it not only saves 50% of nutrient inputs but also greatly reduces the cost of every ton of spirulina farming. In addition, the industrial wastewater of the power plant is also recycled with an annual recycling capacity of 1 million tons.  Also every year, the plant is capable of utilizing the ash produced from the burning of Salix to produce 8,000 tons of compound fertilizer.  This shows that the power plant is capable of producing clean emissions across the three sectors.

Waste smoke from power generation has been reused in the Spirulina farming industries. It not only realizes the value of exhaust gas and lowers the production costs but also creates new business ventures. Moreover, residual heat from the power generation also provides heat for Spirulina farming via related technology which in turn reduces the production costs, serving multiple purposes.
