Rabbit King’s Bio-gas Kingdom

 

   Chairman Ren Xuping of Dayi Xuping Rabbit Corporation is well known as “Rabbit King”, but there are more and more people calling him and consulting about bio-gas, because he is now also known as “King of bio-gas”. 

Coming into the Xuping modern breeding farm, located in the Xieyuan town,   you will feel that it is an ecological garden, with flowers everywhere, beautiful   lamps by the sides of roads and a pound with fish playing quietly and a nice smell flying from the dinning hall, while the trainees are taking a shower using a 7 L water heater. “All that thanks to our bio-gas tank”, as Ren Xuping proudly said.

The tank, 110 cubic meters of volume, resolves yearly the dejecta from 150,000 rabbits and produces bio-gas enough for 80 people’s daily life. The tank is embedded in the ground with one tube exposed above the cover and extending to the kitchen, toilets and the yard for cooking, taking bath and lighting. And one pipe, with a pump fixed on it, transmits the waste fluid to the grass land on a 70 meter high slope behind the farm. While the solid disposals can be
blended with soil of flowers to make them prosperous.

The first tank of 46 cubic meters was built in 2003, which inspired him a lot. So, the large one has been completed at cost of 60,000 RMB. “Before, I was required to do so, but now I myself want to do it”, Ren Xuping told a journalist. He would like to explain bio-gas benefits to any one who he would meet. Under his encouragement, there have been more than 80 households of his rabbit association having their own tanks.
   Ren Xuping speculates, as he told the journalist, that to develop as an industry combining together rabbit breeding with bio-gas production, every village concentrating on rabbit breeding can build one large-scale bio-gas tank, which can resolve the fuel problem of the whole village. The gas after treated may also be used by dry diesel engine for electric power generation or as fuel of steam boilers. “The gas may also be compressed for vehicle use”, as he described, “Then, our rabbit breeding villages will be really ecological communities”.

      It is estimated that only one year is needed to recover the total cost, if to build 8 cubic meter bio-gas tank at expense of 1400 RMB covering labor, construction material and stove tools, but it can generate an economic increase by 1000 RMB a year due to 450 cubic meter gas and 5 ton organic fertilizer to be produced, for the fertilizer helps improving the quality of grain seeds, killing parasite eggs, optimizing crop growth and thus increasing agriculture productivity.
