Environmental Friendly by Others

 

Green Bags ( Non-Woven Bags )

Green bags are made by polypropylene ( PPSB ), which is a fossil fuel based plastic. While most of people state that this can be re-usable, and multi-used in many times. However, even the best environmental intention of mind, sometime you may forget to bring along, and end up to buy a plastic bag or purchase another green bags.

And also, a lot of green bags taken as promotion items, and these bags are finally stored at home.

Paper Bags

Although paper bags seems to be environmental friendly.

However, it takes four times more of energy to manufacture a paper bag compared to a bio-degradable plastic bag ( Comparison is based on cutting the trees from forest to a piece of paper, and the crude oil to polybags ).

 

In Recycling Paper & Recycled Plastic Bags

Recycling Paper will takes 9 times more of energy, in compared to the same weight of recycling plastic bags.*

 

Additionally, most of the paper bags or boxes are coated with a laminated film, as the protection of printing and glossy finishes. The film gives the paper bags extra difficulty in recycling process, where plastic film cannot decompose in landfill.

Plant for Bio-Plastic

Plant based plastic is either PLA or PSM material.

Takes PET as an example, PET with its MEG ( mono-ethylene glycol ) made from sugar crane of plants, the ethanol derived from sugar crane, has to be converted into MEG through a series of process, and then MEG polymerizes with PTA to form PET resins.*
