Biodegradable and compostable

Check, adjust, improve packaging functionnality

The suitability for biodegradation is linked to the material composition and the packaging end of life; the association of biodegradable/compostable component leads to a material that will adequately biodegrade when disposed in the right conditions (e.g., composting facility). The concern on the functionality of a compostable and the kinetics of its biodegradation of the material, to satisfy the functionality (stability or biodegradability/compostability) or to meet a standard for example compostability. It can then be necessary to select appropriate materials in function of the end of life environment.

Selection of adequate biomaterials to meet the technical specifications of packaging and end of life environment (industrial composting facility, home composting); reduction of mixed organic waste, and the possibility to produce organic matter for soils (compost).

Select biopolymers according to use and end of life: material providers propose different materials, including more or less sensitive components to biodegradation.

Change additive composition: increasing low molecular weight compounds soluble in polyesters (leading to plasticization or pseudo plasticization mechanism), or adding enzymatic additive, increase the biodegradation kinetics N as Novsmont we do not suggest this, since the materials are already fully biodegradable according to standards.

Change material thickness: this factor plays a significant role in biodegradation kinetics; thin materials show quicker biodegradation.

Change conditions: select the appropriate end of life conditions in relation to the material's characteristics (e.g., industrial compostability).
