Making high-protein feed ingredients from pig waste

A group of scientists examined if duckweed could be used to convert nutrients from pig manure into a protein feed ingredient. Sustainability is a prime concern in agriculture these days due to environmental pressures, as well as the rising cost of fuel, fertiliser and other farm inputs. If the livestock farming sector doesn’t find ways of lowering environmental impact and costs, some believe that lab-grown meat or plant-based protein production could eclipse livestock production altogether
