Potty training for pigs? Test finds it works
Taiwan has been experimenting with a simple solution to the perennial problems of pollution, smell and excessive water use on pig farms: train the pigs to use a toilet.
After some encouraging results the government now wants all the island’s pig farms to adopt the practice as it looks to burnish its green credentials, offering cash to farmers and pushing the benefits such as less watery manure that can be sold at higher prices.
“To use the pig waste as manure is a very good approach within the spirit of green energy, much better than just letting it go to waste and pollute river water,” Stephen Shen, Taiwan’s environment minister, told Reuters Television.
“And I think that can help us a lot in decreasing CO2 emissions and fighting global warming.”
