Plastic Ban Order Makes Biodegradable Products A Promising Future.

Compostable materials go a step beyond biodegradable materials by breaking down into natural components and becoming a part of healthy soil.

In the 1970s, plastic shopping bags were still a rare novelty, and now they have become a ubiquitous global product with an annual output of one trillion.

From 2008 to 2018, emerging Internet industries such as e-commerce and takeaway have witnessed explosive growth.

Polylactic acid (PLA) is a new kind of bio-based and renewable biodegradable material​. PLA is made from starch materials proposed by renewable plant resources (such as maize, cassava, etc.).

PLA takes annually renewable resources – corn, cassava and other plants as raw material. After fermentation by microorganisms, lactic acid will be extracted.

There are various types of plastic materials claim to be biodegradable, but many of them are not truth!

A peer-reviewed Life Cycle Impact Assessment of PLA (polylactic acid) has been published that confirms the low carbon footprint of Total Corbion’s PLA at commercial scale.

While bio-based polylactic acid (PLA) thermoplastic is relatively eco-friendly and easily recyclable, composites such as carbon fiber are much stronger.

Nairobi, 11 March, 2018 – The global fight against plastic pollution comes into sharp focus at the Fourth UN Environment Assembly this month in Nairobi, Kenya, with the launch of three reports each addressing different aspects of, and solutions for, the growing impact of plastics on the world’s marine environments.

ALBANY, N.Y. (AP) — The halt on China’s imports of wastepaper and plastic that has disrupted U.S. recycling programs has also spurred investment in American plants that process recyclables.

A: Degradable materials refer to a class of materials that can meet the requirements of application during use and storage, and can change chemical structure in a short period of time under certain environmental conditions and lose material use performance. Degradable materials are classified into common degradation materials and biodegradable materials. Biodegradable material refers to a degradation material that can be converted into carbon dioxide and water within 180 days by the action of microorganisms under composting conditions. Not all degradation materials are biodegradable materials.

A: Such as photo-oxidative degradation plastics, which are not real biodegradable plastics, but this photodegradable material is the first to popularize the concept of degradation, probably in the 1960s and 1970s. Photooxidation plastics, which are ordinary petroleum-based plastics, add some additives that can cause the breakage of petroleum-based plastic molecular chains by the action of sunlight, so they can become plastic fragments under the action of light. This degradation has relatively large defects: the first photodegradation does not really achieve degradation, and the second decomposes into plastic fragments, which have a very serious impact on plants and microorganisms, and also produce microplastics.

A: This type of destructive biodegradable plastic is a natural appearance of natural substances such as starch, wheat flour, rice flour or bamboo fiber, which is added to conventional plastics to achieve so-called biodegradation. Although natural materials can degrade, the rest of the plastic is still plastic. Therefore, such destructive bioplastics are not completely biodegradable plastics. Some people say that it is partially degraded, but partial degradation is the real harm, because the so-called partial degradation refers to the degradation of natural materials, so that the remaining petroleum-based plastics are destroyed, but the recovery value and use value are lost. It gradually ages in nature and becomes plastic. Its hazard is similar to the photodegradable plastics. It causes traditional petroleum-based plastics to become debris and remains in the soil, causing soil compaction, microbial death, soil erosion and so on. This material has a more terrible place because it looks environmentally friendly
