The current development status of bio-based chemical fibers: total output is nearly 500,000 tons.

During the 500 years of industrial civilization, the utilization of fossil resources has greatly promoted the technological progress of human civilization, but it has also caused severe damage to the Earth's ecology.

Fully biodegradable mulching film enables a win-win situation for environmental protection and increased production.

To address the pollution caused by traditional plastic mulch, the state has introduced a series of policies to encourage and support the application of fully biodegradable mulch. The use of fully biodegradable mulch helps enhance soil vitality, achieve sustainable land use, and contribute to the green development of agriculture and the construction of a prosperous countryside.

It was first discovered that polylactic acid (PLA) can degrade under mild conditions at 37℃.

Amid the rampant plastic waste, although the biodegradable plastic poly(lactic acid) (PLA) is highly anticipated, it is confronted with the problems of slow industrial composting degradation and difficult monomer recovery. Recently, a study by the Italian Institute of Technology found that the lipase secreted by Aspergillus oryzae can efficiently decompose PLA materials under mild conditions, providing a green new solution to the problems of PLA degradation and lactic acid recovery.

The United Nations has called for an end to plastic pollution.

According to a report on the website of Spain's La Vanguardia on June 4th, it seems that we are addicted to plastic. Humans produce over 430 million tons of plastic every year. Plastic is everywhere in our lives and poses a major problem for the environment and human health. Scientists have proved that we are eating and breathing plastic.

L-Lactic Acid: From Food to Environmental Protection, Unlocking the "Golden Key" to a Green Future

In 2024, the global biodegradable plastic market witnessed explosive growth. International giants such as Coca-Cola and Nestlé launched PLA packaging products one after another. The core raw material of this eco-friendly material - L-lactic acid - has quietly become an "invisible champion" in the green economy. Take Henan Jindan Technology, a leading domestic enterprise, as an example. In 2022, its L-lactic acid revenue exceeded 860 million yuan, and its products were exported to Europe and America, becoming a key link in the global supply chain. How did this seemingly ordinary "acid" rise from a food additive to a strategic resource in the bioeconomy? Let's uncover the technological secrets and business landscape of L-lactic acid.

The global campaign to curb plastic pollution has made positive progress.

Recently, in the southern French city of Nice, ministerial officials from 40 countries around the world held a closed-door meeting this week, aiming to promote the formulation of a legally binding global treaty on plastic pollution. This treaty will be the first to comprehensively regulate the entire life cycle of plastics - from production, consumption to waste management - with the aim of addressing this increasingly severe environmental crisis.

The content includes: scope of biomass standards, normative reference documents, terms and definitions, site selection for material yards, layout of material yards, stacking in material yards, and storage.

Italy has released a new compostable packaging label.

To facilitate citizens and enterprises in correctly disposing of biodegradable and compostable plastic packaging into the wet waste recycling system, the Italian Biorepack Alliance has launched a new voluntary label "Organico Biorepack". Packaging producers can use this label to prove that their products belong to the extended producer responsibility (EPR) system specifically designed for organic recycling.

Inner Mongolia is continuously promoting a circular economy and plans to apply 660,000 mu of fully biodegradable mulching film by 2025.

In recent years, the Inner Mongolia Autonomous Region has implemented a comprehensive conservation strategy, promoted the efficient and intensive use of various resources, accelerated the establishment of a waste recycling and utilization system, and advanced the in-depth development of a circular economy. Currently, the basic management system for the circular economy in the region is increasingly improved, and the efficiency of resource utilization continues to be optimized.

Academician and expert advice on sustainable development of plastics: Increase support for research and development of new biodegradable plastics

On June 7th, a high-end academic salon on "Green and Sustainable Development of Plastics" was held at the Institute of Physics and Chemistry of the Chinese Academy of Sciences. Several academicians and experts discussed the current status and prospects of related technologies such as plastic recycling and circular utilization, bio-based plastics, and biodegradable plastics from the perspective of scientific and technological development, and planned the key directions for the sustainable development of the plastic industry in the future.

Amid the fierce competition among biodegradable materials, why can polylactic acid (PLA) stand out?

Polylactic acid is a new type of biodegradable material based on biological resources. It is made from renewable plant resources such as corn and straw through saccharification, fermentation and polymerization to form a high-molecular polymer. Starch, cellulose, hemicellulose and other polysaccharides in crops are decomposed into monosaccharides such as glucose by various biological enzymes; then through biological fermentation technology, microorganisms (such as lactic acid bacteria) are used to ferment and metabolize lactic acid. After purification treatment, high-purity L-lactic acid is obtained; then, through chemical synthesis technology, high-purity L-lactic acid is polymerized into high-molecular-weight polylactic acid.

A major breakthrough in the recycling of polylactic acid (PLA) from the team of Zhang Tierui at the Institute of Physics and Chemistry.

Professor Zhang Tierui's team has combined photothermal depolymerization with photocatalytic reforming, pioneering a more efficient PLA recycling process, marking a significant leap towards a circular life cycle for bioplastics.

The new express delivery regulations are about to be implemented, and "green" packaging is making its debut.

Starting from June 1st, the revised "Interim Regulations on Express Delivery" (hereinafter referred to as the "Regulations") has been officially implemented. It has filled the institutional gap in China's regulation of express delivery packaging, and clearly defined the responsibilities of relevant entities at each link in the entire process.

Which is the best among the three methods for PLA fiber production: melt spinning, solution spinning, and electrospinning?

PLA fiber material is a new type of biodegradable material based on biological sources. It is a polymer obtained by polymerizing lactic acid as the main raw material. The raw material sources are abundant and renewable, mainly corn, cassava, etc. It can be processed by various methods such as melt spinning and electrospinning. Due to its good biocompatibility, easy degradability and renewability, PLA fiber material has a good application prospect in the fields of biomedicine, filtration and separation, packaging, etc. This study mainly explores the preparation of biobased PLA fibers.
