Microplastics: A threat to the future of farming

Leading sustainable plastics manufacturer, Symphony Environmental has urged farmers and growers to halt their use of ordinary plastic mulch films that are capable of contaminating soil and affecting food quality, thus calling for new plastic-manufacturing methods

To prevent the ongoing environmental damage caused by plastic pollution year after year, CEO of Symphony Environmental, Michael Laurier argues that farmers and growers must switch to the right kind of biodegradable plastic. To protect crops and reduce water evaporation, farmers and growers generally spread plastic mulch films on their fields. However, conventional plastic films cannot be recycled easily after use due to contamination and degradation. Moreover, when being removed from the field post exposure to sunlight and weathering, they tend to release fragments and microplastics that are extremely detrimental to the environment. 

Replacing normal polyethylene with Symphony's NbR resin is considered more environmentally friendly due to its ability to biodegrade after the harvest , without needing to be collected and transferred to a composting facility. Its degradating can be programmed to occur in the timescale required for each crop type. It will then act as a carbon source for next year's plants.

“This resin can be produced by mulch-film manufacturers at lower cost than normal polyethylene using their standard equipment, as it contains 20% less fossil-derived plastic,” said Laurier. “Plastic pollution of the countryside needs to be addressed urgently, and farmers and growers now have the opportunity to do this at no extra cost.”
