Eco-friendly materials brand LETZero
2022 LETZero Product Book
LG Chem has published a product book containing LG Chem’s Eco-Friendly Materials
Brand LETZero products.
LETZero is a master brand that integrates eco-friendly materials such as PCR made of
reprocessed waste plastics, bio materials made of Bio-based renewable materials, and
biodegradable materials made of glucose and waste glycerol extracted from corns.
We introduce LG Chem’s eco-friendly product line for sustainable environment and
future through Product Book.
Product Group
Recycled Products
LG Chem has developed Post-Consumer Recycled (PCR) materials by collecting, pulverizing, and sorting discarded plastics used by end consumers with LG Chem’s proprietary technology. We also produce circular materials by chemically recycling plastic film and composite plastic that are discarded. LG Chem’s PCR material reproduces the quality equivalent to virgin plastic. We have successfully produced PCR plastics that are transparent or close to pure white that require a high level of technical difficulty. Various eco-friendly certifications for these products are available upon customer request. This use of waste plastics reduces carbon emissions through sustainable waste disposal and the production of fewer energy products.
Manufacturing Process
Mechanical recycling
After collection, plastic wastes are classified by type. Once the impurities are removed by cleaning and sorting, the plastic waste is recycled through the regeneration process. LG Chem combines high-quality recycled materials and other materials to produce virgin-quality recycled plastics. LG Chem provides certification for PCR content from eco-friendly certification bodies such as UL ECV (Environmental Claims Validations), TUV (Technical Inspection Association in Germany), and GRS (Global Recycled Standard) upon customer request.
Chemical recycling
Waste vinyl and composite plastics, which are difficult to recycle mechanically, produce pyrolysis oil at the raw material level (naphtha) through chemical recycling (pyrolysis). It is used in the manufacturing of chemical recycling products by replacing the raw materials in the existing fossil fuel-based processes. Because the pyrolysis oil-based raw material does not change the physical properties of the final product, it can be applied to all products. ISCC Plus (Circular Economy) certification for these products can be provided upon customer request. The chemical recycling technologies above allow us to reduce carbon footprint during product manufacturing and dispose of waste in a sustainable way.

Biodegradable Products
LG Chem is leading the development of plant-based bio materials that decompose in soil within months. In addition to reducing carbon emissions as required in the global market, we are developing bio-based and biodegradable products that have versatile applications, such as plastic bags and disposable cups, in response to tougher regulations on disposable products and increasing demand for biodegradable materials.
Manufacturing Process
PLA
PLA is produced from lactic acid, obtained by fermenting glucose extracted from corn starch or sugarcane. After converting lactic acid to lactide, its cyclic form, PLA is manufactured through a polymerization process. Depending on the mixture of raw materials and the polymerization process, PLA can be produced in various grades. It can diverse applications through compounding with other materials that can compensate for its weaknesses in physical properties.
PLH
PLH is a biodegradable material independently developed by LG Chem, produced by 100% bio-based materials. 3-HP (3-Hydroxypropionic acid), one of the monomers used to polymerize PLH, is derived from microbial fermentation using biomass. Because it is difficult to achieve high-purity and high-yield production of 3-HP and it is extremely complex to refine, the material had not been previously mass-produced. But after long-term research, LG Chem successfully developed the production and refining technology for 3-HP. This enabled the development of new biodegradable material with improved flexibility that still maintains transparency.
PBAT
PBAT is made from three organic compounds: BDO (butanediol), AdA (adipic acid), and TPA (terephthalic acid). To these, polylactic acid (PLA), which is a biodegradable plastic, starch, and/or cellulose are compounded to regulate their physical properties. In addition to the biodegradation effect, the carbon emissions produced in the product manufacturing process can be minimized by using bio-based materials in the raw material stage.
Bio-balanced Products
LG Chem produces a variety of products using renewable plant-based materials. We apply the biomass balance technology to incorporate plant-based materials, which uses less fossil fuels and contributes to the reduction of carbon emissions. LG Chem became the first to acquire the ISCC PLUS certification in Korea for the entire process, from purchase to production and sales performance of 41 eco-friendly products, including SAP (super absorbent polymer), PO (polyolefin), ABS (acrylonitrile butadiene styrene), and PVC (polyvinyl chloride). (As of July 2022) We are also developing polyamide, polyester, and thermoplastic elastomer products using ingredients extracted from plant-based materials.
Bio-Circular Balanced (BCB) products
We are able to utilize the existing petrochemical production infrastructure by incorporating bio materials from renewable plant-based oils into fossil fuel-based raw materials. Our plants are also capable of eco-friendly production using renewable energy such as solar and hydropower.

Bio-based products
A wide range of plastics can be synthesized using compounds of alcohol, acid, and amine obtained by decomposing/fermenting starch extracted from corn and sugarcane. The synthesized plastic is used in various applications by reinforcing physical properties through additional compounding processes.
