Nursery Pot and Tray Compound (Compostable)

About This Product

A compostable compound of polylactic acid and polybutylene adipate terephthalate, melt-compounded and pelletised. PLA gives the wall its rigidity and PBAT its flexibility and resistance to cracking at the rim, and the blend is supplied for either thermoforming or injection, depending on the pot format. Plastic nursery pots are a persistent waste stream in horticulture: contaminated with soil, low value, and rarely recycled. A compostable pot can go into green waste with the growing medium, which removes the separation step that defeats recycling. The difficulty is that the pot sits in warm, damp, microbially active medium throughout its working life, so the conditions that will break it down are the ones it must first survive. The pot must hold its structure through the growing period, watering and handling, then break down afterwards. That service life is the key specification and is matched to the crop cycle, through polymer ratio, molecular weight and wall thickness rather than an additive that switches degradation on. Supplied as a raw material for processing on the buyer's own line. We do not produce finished articles. It is used in nursery pots, propagation trays and supply to horticulture and garden centres. Bio Green Chem supplies this nursery pot and tray compound to specification on polymer base, pellet form, forming route, colour and the service life your crop cycle requires.
