We are aware that there were overseas brands selling degradable trimmer line. The material used to produce these products are now banned in most countries and will soon be banned in NZ also, so you will eventually no longer see these products. To make trimmer line degradable, these manufacturers use an additive that causes the nylon to break down into very small bits, essentially creating micro plastics. We have chosen NOT to do that. Until such time as suitable and genuinely biodegradable raw materials for trimmer lines are available, we will continue to produce our trimmer line from the best quality nylon. By using a very good quality conventional nylon, we hope to reduce the number of times your line breaks (causing pieces of trimmer line to be left behind) and so keep possible pollution to a minimum. We are committed to finding an environmentally responsible solution to the problem and that is why we are currently testing several raw materials and composites that could provide genuinely biodegradable alternatives.
