Bio-Polymers & Bio-Compounds Explained

Bio-polymers and bio-compounds are classified as biopolymer because they are bio-based, biodegradable, or feature both properties. Spectabio and Bioblend bio-polymers and bio-compounds are all at least biodegradable in their target environment and are labelled with “Made to Degrade”.



The term "biobased" means that the material, compound or product is derived from biomass (plants, agricultural by-products, agricultural waste, etc.). It can additionally be filled or be reinforced with natural fibers, mineral fillers or other biomass.

Bio-based materials refer to a new class of materials that are produced by biological, chemical, and physical methods using renewable biomass including crops, trees, other plants, and their residues and inclusions. Polylactic acid, polyhydroxyalkanate, starch, cellulose, straw, chitin, and gelatin all belong in this category. Bio-based products mainly refer to lignocellulosic agricultural and forestry wastes such as straw other than grain.

Biodegradation is a chemical process during which microorganisms that are available in the environment convert materials into natural substances such as water, carbon dioxide (CO2), and compost (no artificial additives needed). The process (e.g. time) of biodegradation depends on the surrounding environmental conditions (e.g. location or temperature), on the material and on the application itself.

Biodegradable in soil/sea-water

Biodegradation in soil refers to degradation to CO2 corresponding or exceeding 90 w.-% within 2 years in soil. Spectabio B / T grades and Bioblend B / T grades can be considered as biodegradable in soil/sea-water.

Compostable (according to EN 13432)

Compostable addresses the following characteristics: biodegradability (namely the capability of the compostable material to be converted into CO2 under the action of microorganisms; the standard contains a mandatory threshold of at least 90 % biodegradation that must be reached in less than 6 months), disintegration during biological treatment (namely fragmentation and loss of visibility in the final compost), effect on the biological treatment process (namely no negative effects on the composting process) and effect on the quality of the resulting compost (amount of heavy metals has to be below given maximum values, and the final compost must not be affected negatively). All materials labelled with “Made to Degrade” are compostable according to EN 13432 (Spectabio and Bioblend line).


Compostable plastics can be completely decomposed by micro-organisms, enzymes produced by special bacteria can break down the flexible polymeric chains of materials into small molecules. These small molecules and other organic materials such as organic waste, are then digested by micro-organisms, which eventually allow water, carbon dioxide, and biomass to remain. For example, polylactic acid (PLA) can be decomposed into water and carbon dioxide in soil, sewage, rivers, and oceans under the action of micro-organisms such as bacteria in just 3-6 months. Throughout this cycle, there is no need to recycle or compost, the total amount of water and carbon dioxide is balanced. The greenhouse effect in the atmosphere is not increased and no pollution is caused to the environment.

Reduction of CO2

Bio-polymers and bio-compounds contribute to the reduction of Greenhouse Gas emissions or can be carbon neutral. Plants, bamboo and rice husk absorb atmospheric carbon dioxide (CO2) as they grow. Using this biomass (through biobased polymers, through natural fiber reinforcements or both) to create products constitutes a more permanent removal of CO2 from the atmosphere.


Contribution to the Circular Economy

With reference to global waste hierarchies, biodegradable polymers and compounds can provide added value through organic recycling (i.e. industrial composting and anaerobic digestion) as an additional waste treatment option. Industrially compostable polymers certified according to the harmonised European standard EN 13432 contribute to efficient waste management and circular preservation of resources.

Spectabio and Bioblend Grades

Spectabio and Bioblend grades are bio-polymers and bio-compounds being compostable according to EN 13432, hence rated as biodegradable (in industrial compost conditions). Spectabio B and Spectabio T grades are also biodegradable in soil and sea-water. Spectabio grades are reinforced with bamboo fibers, rice husk and wheat straw/husk. Bioblend grades are blends of different biopolymers filled with mineral fillers. All  compounds have improved thermal and mechanical properties with reduced cost levels.


Spectabio compounds

All injection moulding grade materials are delivered as compounds suitable for injection moulding on standard equipment. To suite different product needs, we have grades with varying mechanical, thermal and processing properties. All grades are ready-to-use feedstock moulding grades. Based on specific needs, we can tailor and customize all material grades to customer requirements.
