Pig Palace: Where little goes to waste

Raising pork comes with problems worldwide. Now, innovative Chinese farmers are using science in a circular system to improve the quality of meat and eliminate the usual pollution.

House of straw. House of sticks. House of bricks. And now the legendary Three Little Pigs can choose a multipurpose scientific greenhouse with a comfortable fermentation bed.

With its spacious, clean grounds, rows of immaculate greenhouses, pleasant trees and almost no foul odors, this is no ordinary pig farm. Refreshingly lacking is the churned-up excrement, the stench and the polluting byproducts of a traditional operation.
