How can the use of plastics in agriculture become more sustainable?
It is impossible to imagine modern agriculture without plastics鈥�12 million tons are used every year. But what about the environmental consequences? An international team of authors, including McGill Department of Bioresource Engineering Professor Jan Franklin Adamowski and Department of Food Science and Agricultural Chemistry Associate Professor and Chair聽St茅phane Bayen, addresses this question in a recent study.
Their research, newly published in聽Communications Earth & Environment, reveals that plastic plays a multi-faceted role: from mulch films that protect plants to water-saving irrigation systems, plastic is deeply embedded in our food production. The article reviews the benefits and risks of using plastics in agriculture, and identifies solutions that ensure their sustainable use in line with global initiatives like the UN Plastics Treaty.
Adopting these practices will foster more sustainable use of plastics in agriculture, according to the scientists. While a complete replacement of plastics is untenable at present, the judicious use of alternatives with minimal environmental impact seems to be a promising way forward. With mandatory monitoring, technological advancement and educational initiatives, reducing our reliance on plastic and its adverse environmental impacts should be possible.
