Biodegradable Nowovens

Product Description

PLA is a biodegradable thermoplastic derived from lactic acid.

It resembles clear polystyrene, provides good aesthetics (gloss and clarity), but it is stiff and brittle and needs modifications for most practical applications (i. E. Plasticizers increase its flexibility).

It can be processed like most thermoplastics into fibres, films, thermoformed or injection moulded.

Used for compost bags, plant pots, diapers and packaging.

Creation: Lactic acid can be obtained on the basis of renewable starch containing resources (e. G. Corn, wheat or sugar beat) by fermentation, or by chemical synthesis of non-renewable resources.

Disposal: If composted properly it takes 3-4 weeks for complete degradation.

The first stage of degradation (two weeks) is a hydrolisis to water soluble oligomers and lactic acid. The latter, as a naturally occurring substance, is a rapid metabolisation into CO2, water and biomass by a variety of micro-organisms.
