\"Chen-9967569f-84ef8e6f@600w2x\"A professor of food science and technology at Singapore\u2019s Nanyang Technological University, William Chen has invented a biodegradable food wrap made of cellulose and extracted from the waste generated by soybean product manufacturers.<\/strong><\/p>\n

The soybeans are first crushed to squeeze out juice that\u2019s used to make bean curd and soy milk. The residue is then fermented by microbes that consume the nutrients, leaving behind cellulose, a form of fiber.<\/p>\n

Cellulose-based plastic wraps have been on the market for a few years but Chen says that most are made from wood or corn, cultivated for that purpose. By contrast, his wrap is made from a waste product \u2014 so it doesn\u2019t compete with edible crops for land and is more sustainable.<\/p>\n

Chen\u2019s technology could help to solve two problems at once: cutting plastic production and reducing the amount of food waste deposited in landfill. \u201cIn Singapore, the amount of food waste we generate every year can fill up 15,000 Olympic-sized swimming pools,\u201d he says, adding that because soy products are so popular in Singapore, 30 tons of soybean residue is produced there every day.<\/p>\n

F&N, a soy-based drinks producer, has partnered with Chen\u2019s lab and provides the residue, straight from the factory. The company is conducting a feasibility study to assess whether the food wrap could compete, commercially, with conventional products, says Chen.<\/p>\n

Scalability is sometimes an issue with bioplastics, which are typically more expensive to produce than their petrochemical counterparts. The soy-based wrap costs \u201calmost nothing\u201d to make in the lab, says Chen, because the raw materials are free of charge.<\/p>\n

Commercial scale production would involve additional expenses, such as storage and quality control, however \u201cwe have not calculated those costs yet,\u201d says Chen.<\/p>\n

Chen’s soybean-based plastic wrap is digested by microbes and disappears completely within a month when disposed of in general household waste, without the need for heat.
\nChen says he hopes neighboring soy-loving countries will be inspired by Singapore and adopt his innovation. He adds, \u201cMy dream is that our technology, which is cheap and simple to implement, will cut plastic and food waste and create a cleaner environment.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
