GLASEL ECO PROJECT
In response to increasing awareness of environmental and energy-related issues such as global warming and the depletion of oil reserves, GLASEL has taken note of eco-friendly materials such as plant-based plastics (biomass) and paper. It is also making greater use of refill containers, plastics-saving containers, and glass containers.
Project 1: Eco-friendly materials
Plant-based plastics (biomass)
The focus is now on carbon-neutral* plant-based plastics (biomass), which impose a lower environmental burden, as substitutes for conventional petroleum-based plastics.
GLASEL works with many types of eco-friendly plastics. In particular, bio-PE and bio-PET can be used in a similar manner to conventional PE and PET.
Plastics made from plant material are environmentally friendly because they do not theoretically result in net CO2 emissions even if they are incinerated on disposal, as the plants from which they are made absorb CO2 as they grow.
Bio-polyethylene (bio-PE) is manufactured using ethylene derived from bioethanol, which is made from plant material as its raw ingredient.
Bio-PE featured in this catalog is made from bioethanol. This bioethanol is produced by fermenting molasses, which is the residue from refining sugarcane juice into sugar in most cases. As it is produced from molasses, it does not affect or compete with food (sugar) production.
If made from bio-PE, polyethylene moldings will be 96% biomass-derived. This is equivalent to an approximately 70%* reduction of CO2 (greenhouse gas) emissions compared with petroleum-based PE.

Bio-Polyethylene Terephthalate (bio-PET)
As with bio-PE, bio-PET featured in this catalog uses bioethanol as a raw material derived from sugarcane molasses.
Molasses is the residue after refining sugarcane juice into sugar. Bio-PET is made by the polymerization of bio-monoethylene glycol (biomass MEG) produced from molasses and high-purity terephthalic acid (PTA).
If made from bio-PET, polyethylene moldings will be 30% biomass-derived. This is equivalent to an approximately 20%* reduction of CO2 (greenhouse gas) emissions compared with petroleum-based PET.

Items produced from bio-PE/PET are virtually the same in color tone as those from conventional PE/PET.
Regarding heat resistance, impact resistance (drop test) and workability (e.g. printing), bio-PE/PET are similar to conventional PE/PET. Bio-PE/PET are odorless and pose no problem in chemical resistance properties.
Please always test the container’s resistance to the contents.
Bio-PE and bio-PET can be molded using conventional molding machines and molds used with PE and PET.
The material codes for bio-PE and bio-PET are “PE” and “PET.”
If a product is at least 25% derived from biomass, it is permitted to bear the BP logo of the Japan BioPlastics Association (JBPA). Bio-PE and bio-PET qualify for the BP logo.
To use the BP logo, you need to register with JBPA as a member and have your products individually registered and certified (at cost).
This eco-friendly material contains 51% paper powder as the main ingredient. The material is categorized as a paper product and can be disposed of as combustible trash.*1 When incinerated, it does not generate dioxins or any other toxic gases and cuts CO2 emissions by about 28% compared with general plastic materials.
Molds designed for AS/ABS can be directly used to mold*2 the material.
＊1 Comply with the rules set out by your local municipality.
＊2 Some of our products are made from paper.Please contact us for more information on paper
The material code for this material is “paper, PP.”
Containing paper as an ingredient, the chemical resistance of the material is lower than that of general plastic molded products.
