Biogas: Transforming Waste into Power

The video discusses a large-scale egg production farm near Beijing that recycles chicken manure to generate electricity. The farm, which houses 3 million chickens, produces 1.4 million eggs daily and generates over 200 tonnes of manure. This waste is used to produce methane, powering a generator that supplies electricity to the farm and the central grid. The byproducts are used as fertilizer, enhancing soil quality and farm efficiency while reducing waste and increasing profits.

What is one of the main reasons for the large-scale food production in China?

• To export food to other countries

• To support a large population

• To reduce food prices

• To experiment with new farming techniques

How is chicken manure initially processed at the D King One Egg farm?

• It is used as raw fertilizer

• It is mixed with wastewater and fermented

• It is stored for future use

• It is burned directly for energy

What is the primary use of methane produced from chicken manure?

• To heat the chicken coops

• To create synthetic fertilizers

• To power a generator for electricity

• To sell as a cooking fuel

What happens to the surplus electricity generated at the farm?

• It is stored for emergencies

• It is sold to the central grid

• It is used to power nearby towns

• It is wasted

How does the waste-to-energy process benefit neighboring farms?

• By providing free electricity

• By reducing local pollution

• By supplying improved soil quality

• By offering free chicken feed
