Earthsave Bio-degradable tape is a non toxic plastic tape with an accelerated degradation process, this process will take 5 - 10 years in industrial landfill which is substantially shorter than the standard plastic tape varieties, and perform just as well. This is a problematic area with hazard marking tapes usually being made from single use plastics which may take hundreds of years to break down and contaminate the ground. This product is a positive improvement, but it isn't perfect and it may be more eco friendly to consider a different approach to mark hazards, if viable and safe to do so, such as signage made from paper based or recycled materials. The manufacturer also makes a donation to friends of the Earth for every roll sold.
