The plastics industry is undergoing critical transformation to achieve the goal of net zero defined in UNFCCC. It is generally accepted that increase in reuse, reduction and recycling are essential actions. However, the latest annual recycling rate is 9% and only 40% of the recycled plastic wastes went to the products though the European area leads the world in awareness of environmental sustainability and recycling infrastructures. Despite of the fact that many countries have implemented incentives for enhancing the reuse and lowering the demands of plastic products, the COVID-19 pandemics dramatically increases the demands of single use plastics giving rise to an opposite consequence.
For achieving UNFCCC’s goal in a more effective approach, the European Bioplastics Association advocates that the use of regenerable biomass to replace or reduce the growth in demand of fossil plastics is critically important. In a perspective of life cycle assessment (LCA), refining and manufacturing of primary raw materials (such as polyethylene, polypropylene, and polyvinyl chloride, etc.) contribute 60% of carbon emission of the entire plastic industry. Apparently, efforts made on reducing or replacing the use of fossil-derived materials gain more effectiveness in lowering carbon emission than that contributed by the later stage of life cycle. Regenerable biomass, such as starch and cellulose, is a naturally synthesized polymer in plants by utilizing clean solar energy along with absorbing carbon dioxide in the air. It is a natural carbon capturing mechanism without consuming fossil energy at all.
According to the data published by the European Starch Association, one ton of air carbon dioxide can be offset for manufacturing each ton of dried starch powder. The results also show that each ton of cellulose produced by sugarcane consumes 2.7 tons of air carbon dioxide. Starch or cellulose is not simply a zero-carbon raw material, but also creates carbon credits for the users if they are appropriately applied.
TwinScrew Industrial Co., Ltd. (herein refer to as “TwinScrew”) foresees user’s requirements for new eco-friendly materials and owns the developed expertise on processing regenerable raw materials such as starch or cellulose. TwinScrew’s tailor-made extruders are successfully manufacturing pellets feeding with starch or cellulosic raw materials. The pelleted products can be easily processed alone or compounded with other polymers for making bio-based products. In a new market segment of green materials, TwinScrew enables clients manufacturing the value-added bioplastic products with a lower carbon burden. Since 2018, the pellets made by TwinScrew’s extruding pelletizing systems have assisted users to manufacturing low carbon, and eco-friendly products by applications of extrusion or injection molding processes. Many of them have been accredited by worldwide institutions such as DIN CERTCO and successfully delivered to the market.
The products listed below are manufactured by use of TwinScrew’s extrusion pelletizing system at customers’ premises.
In recent years, the ESG-implented corporate governance is increasingly emphasized. For an institutional investor it is becoming a critical criterion for valuing the investment. Banking systems also include the ESG performance for assessing the corporate credit. TwinScrew’s pellet production lines provide the most cost-effective solutions to lowering emission in carbon footprint. In the perspective of environmental sustainability of ESG governance, TwinScrew collaborates with clients accessing the leading position.
