Pots manufactured from biopolymers have suffered a setback in recent times for various reasons including price and grower performance. However, companies continue to research the use of biopolymers and Desch Plantpak are currently trialling a biopot that is totally biodegrable in the soil.
There is a wide range of biodegradable pots on the market but for various reasons thay have not yet proved sufficiently biodegradable in the soil, some have to be broken up and composted. Some manufacturers including Desch Plantpac and Poeppelmann have decided that a good option is to manufacture pots from recycled plastics sorted from consumer waste. Another recent introduction in the UK is the Taupe pot (taupe describing its brown-grey colour) made from polypropylene PP that can be collected together with other consumer recyclables. See Taupe Pot & HortiPlastics.pdf 2 Handling characteristics are pretty much the same as ordinary plastic pots. Obtaining the the desirable characteristics for growers at an acceptable price remains the challenge. Even the Taupe Pot is said to be 25-30% more expensive than the tradiional plastic pots. However it is being used by a group of leading UK growers (Wyevale Nurseries will pot into 700,000 in 2019) with the support of the HTA (Horticultural Trades Association) Taupe Pot by Aeroplas (UK) Aeroplas UK Se also Fargro
This does not however detract from the ecological necessity of making pots from bioplastics that are fully and easily biodegradable.
