SUSTAINABLE FARMING. The Department of Science and Technology-Forest Products Research and Development Institute (DOST-FPRDI) has developed biodegradable paper mulch from waste materials to promote sustainable farming. Made of 20 percent abaca-stripping waste and 80 percent old corrugated cartons, the mulch helps improve soil health, boost crop yield, and reduce plastic waste. (Photo courtesy of DOST-FPRDI)
