Introduction Biodegradable Recyclable Recycled
Recycle Bag
Everyone should be very familiar with the topic of environmental protection, such as: plastic bag tax, waste reduction at the source, recycled materials, recyclable plastics, decomposable plastics, and biodegradable materials. I believe everyone is familiar with them. Over the past 20 years, they have often appeared in our lives. After all, how are they defined in the field of environmental protection? How does it work? Can the ideal of environmental protection be realized?
In Hong Kong, the first phase of charging for plastic shopping bags was implemented on July 7, 2009, covering more than 3,000 retail outlets, mainly large supermarket chains, convenience stores, and health care and cosmetics stores. After the implementation, the use of 660 million units per year has been reduced to 150 million units per year for the first time. This effect is very significant.
Despite the initial success of the plan, its coverage is limited. Outside the regulated retail sector, the disposal of plastic bags in landfills is still increasing. Therefore, in May 2011, the government launched a three-month public consultation on whether and how to expand the plastic bag levy plan. On the whole, the public supports the expansion of the scope of the plan to the entire retail industry to further address the problem of using plastic shopping bags in Hong Kong.
Regarding environmental issues, the plastic bag industry has introduced many solutions in the past two decades, and has also derived different technologies to meet the details of the environmental protection requirements of various governments, including: non-woven bags, nylon bags, cloth bags, linen bags, recyclable plastic bags, photolysis plastics, bacterial decomposition plastics, water-soluble plastics, resin cell-forming plastics, starch plastics, polylactic acid and plastic alternatives synthesized from various natural raw materials.
Recently, scientists discovered that Wax worms can eat and decompose common polyethylene plastic bags, decomposing 1400 times faster than other organisms. Scientists believe that this insect may help solve the problem of plastic pollution on the earth.
Studies have found that wax worms eat plastic very quickly. Put 100 wax worms in a 92 mg supermarket plastic bag, and the plastic bag will have small holes after 40 minutes. After 12 hours, the wax worms had eaten the entire plastic bag. Spectral analysis showed that wax worms did destroy the chemical bonds of plastics and converted them into ethylene glycol. Researchers believe that when wax worms digest beeswax, enzymes in their bodies may catalyze similar chemical reactions.
In the past 30 years, similar solutions have derived hundreds of related technologies and products, and the patents involved number in the thousands. However, after these programs are launched, although they can solve some of the problems, they can also meet the standards set by governments for environmental protection (for example: ISO14855, ASTM D 6400, EN13432). However, new solutions cannot always stand the test of pricing. When new products are launched, they are often several times more expensive than plastic products that are still in use today, which consumers simply cannot accept.
We have participated in these related environmental protection technologies in the past 30 years. From environmental protection agents to independent research and development and joint research and development with university laboratories, we are able to master the technology, particularly for food packaging, process and details of various related products. In order to cater to the needs of different customers, and make it simple for them to understand, we will divide the topic into three major categories and introduce them to you one by one:
