Under the background of "carbon neutrality", the sustainable development of plastics has become a hot topic in the industry, and bio-based materials have attracted much attention because of their recyclable characteristics. Bio-based plastics refer to plastics whose processing raw materials come from renewable resources. Its raw materials come from renewable carbon sources in nature, and can be degraded by microorganisms on the basis of certain fermentation and degradation conditions, such as cellulose fibers, poly(lactic acid) (PLA), polyhydroxyalkanoate (PHA), polybutylene succinate (PBS), and so on. Starch-based plastics, PLA, PHA and PBS are the four main varieties of biodegradable plastics with the most research and the largest market scale, and are widely used.
Bio-based packaging for perfumes and cosmetics
Luxury goods group LVMH has announced that its beauty division (LVMH Beauty) will partner with Dow to utilize plastics made from recycled and bio-based raw materials in its fragrance and cosmetics packaging.
Dow's Sarin™ resins are described as ionomers made from chemically recycled bio-based and waste plastic feedstocks, respectively. Since the resin uses bio-based materials such as used cooking oil as raw materials, it reduces the amount of waste residue or by-products generated during the production process, thus preventing over-consumption of land resources and competition with the food chain.
Sarin™ ionomers will be used to make perfume bottle caps and cosmetic cream jars. These materials maintain the premium aesthetics of previous packaging designs while helping to reduce LVMH's carbon footprint, Dow said.
Powder compacts packaged in bio-based materials
Korean makeup brand CJ Olive Young (CJ Olive Young) recently launched a 100% bio-based sourced packaging solution. The brand's makeup line WAKEMAKE Moisture Velvet Matte Concealer Air Cushion Powder, which uses bio-based packaging made of a mixture of PHA and PLA, was launched for sale on December 21 in Korea, according to reports.
CJ Biomaterials, a biomaterials company owned by Korean food conglomerate CJ CheilJedang, provided the packaging solution. CJ Biomaterials, which specializes in the production of PHA, says that using a blend of PHA and PLA enhances the mechanical properties of PLA, such as toughness and ductility, thereby improving impact resistance. The packaging solution replaces the original ABS, a non-biodegradable plastic commonly used in cosmetics packaging.
Bagasse Hot & Cold Cup Lid
Bagasse, also known as sugarcane pulp, is a fibrous material left over from the sugarcane harvesting process. It has a variety of uses and is a sustainable alternative to traditional plastic packaging.BioPak introduces these hot and cold beverage cup lids made from bagasse.
These lids are certified to meet Australian standards (AS4738/AS5810), are compostable for home and industry, and are all made from plant-based renewable resources and are PFAS-free. The weight and thickness of the lid has been verified by multiple testing, along with a unique carabiner that secures the lid to the cup. While many paper-based products can also be composted, the advantage of bagasse is that growing sugarcane does not have an environmental impact similar to that of trees that produce paper.
Home degradation coffee capsules
A 100% bio-based coffee capsule from Coles Group is made from natural materials produced by microbial fermentation, a process that focuses on vegetable oils and their fatty acids. All components of the capsule are certified as degradable for home composting. The body of the capsule is made of a vegetable oil derivative. The material of its capsule is a bio-based compostable material that blocks oxygen and is tear-resistant.
