Chicken
is a favorite, inexpensive meat across the globe. But the bird's popularity
results in a lot of waste that can pollute soil and water. One strategy for
dealing with poultry poop is to turn it into biofuel, and now scientists have
developed a way to do this by mixing the waste with another environmental
scourge, an invasive weed that is affecting agriculture in Africa. They report
their approach in ACS' journal Energy & Fuels.
Poultry
sludge is sometimes turned into fertilizer, but recent trends in industrialized
chicken farming have led to an increase in waste mismanagement and negative
environmental impacts, according to the United Nations Food and Agriculture
Organization. Droppings can contain nutrients, hormones, antibiotics and heavy
metals and can wash into the soil and surface water. To deal with this problem,
scientists have been working on ways to convert the waste into fuel.
