Volunteers pick up discarded plastic bottles during a plogging event in Hong Kong organized by Industrial and Commercial Bank of China. More than 13,000 people took part in the activity, which was held in 280 venues across the country. Photos Provided To China Daily Chilean businessman Roberto Astete has had the same dream for the past years: used plastic cutlery at a diner are automatically sorted into small grinders, then the debris dissolves in water in just a few minutes and is flushed away. We don't need to collect, transport and dispose of plastic waste at special facilities anymore. They can be processed easily on site to reduce ocean pollution, Astete explained. These days, his dream is almost a reality thanks to a new material and processing technology from his Chinese partner. In late July, Astete's company Solubag and Polye Materials in south China's Guangdong Province jointly launched a series of soluble shopping bags in Santiago, capital of Chile, right before the country enacted a new law barring businesses from giving out plastic bags to customers. It takes centuries for petrochemical plastic bags to degrade in the ocean, choking marine animals and harming the entire ecosystem. The bag introduced by the two companies dissolves in water quickly, and Astete even drank the mixture during a press conference to endorse its safety. According to Chen Gang, chairman of Polyrocks Chemical, Polye's parent firm, the bag's raw material is modified Polyvinyl Alcohol, or PVA, which comes from natural gas or calcium carbide. PVA bags dissolve in water in minutes so they won't choke the marine animals. The solution will not pollute water or soil, Chen explained. This alternative to plastic bags is eco-friendly. PVA has been used in paint, glue and textile manufacturing since the 1930s. PVA film has also been widely used for packaging in recent years. However, it was difficult and costly to process this material into shopping bags due to its lack of thermoplasticity, said Cui Yuefei, the bag's inventor and a senior engineer with the South China University of Technology. Cui had spent years on modifying PVA in laboratories and completed his experiments in 2008. By adding certain agents, he made it easier for the material to be pelleted, blow-molded and made into bags. The researcher's work caught the attention of Polyrocks, a reputed fire retardant producer that was trying to explore new business ventures. They joined hands in modified PVA industrialization in 2015. We were looking for a suitable blow-molding machine in the northeastern Chinese city of Dalian in 2016, Cui told Xinhua. That's when and where we met Astete. At that time, the Chilean had been searching for a company capable of and interested in making affordable water soluble bags around the world for over two years. I was in the plastic industry and I thought to myself, we can't use petrochemical bags anymore, Astete recalled. I tried some European and American manufacturers first, but they showed little interest because the profit margin of shopping bags is very small. Then I came to China. Cui and Polyrocks first focused on hot water soluble bags, which would be more durable for everyday use. But Astete, coming from a country with a long coastline, insisted that the bags should be soluble in cold water. The Chilean helped us make this crucial decision in product development, Cui said. A prototype was produced in just two months, and Polye Materials was soon established for the project. The bags launched in Santiago are our third generation products. Their cost is about 1.5 times of that of a normal plastic bag, Cui said. We expect them to be as cheap as normal ones in our fifth generation. Li Lingyu, general manager of Polye told Xinhua that the company's yearly capacity of modified PVA pellets will reach 10,000 tonnes by November. That's about 500 million water soluble bags, she said. Astete hopes the bags will hit the shelves in Chile by the end of this year and has been trying to persuade his Chinese partner to open factories in his country. After the press conference, I got so many calls and there are thousands of inquiry emails in my inbox. It's crazy, really, really crazy, Astete said. We need to further increase our capacity. Eighty-five percent of the inquiry calls are from outside Chile, such as Mexico, Germany, France, and Spain. Polye and Solubag plan to start a joint venture in Hong Kong to deal with sales in the global market. Plastic pollution is considered a major threat to oceans worldwide. At this year's World Ocean's Day on June 8, Antonio Guterres, Secretary-General of the United Nations, called on the world to stop plastic pollution from contaminating the world's oceans. Eighty percent of all pollution in the sea comes from the land, including some eight million tonnes of plastic waste each year, which have resulted in the deaths of one million seabirds and 100,000 marine mammals. Besides Chile, Britain is set to ban all sales of single-use plastics, including plastic straws and cotton swabs. Kenya and Morocco also have similar restrictions. Bags are just the start. We can also use modified PVA to make glass lids, straws, diapers and to replace products made from petrochemical plastics, Astete said. My country is small but people share a similar goal to have a beautiful, clean environment. It's also the aspiration of all humanity. blue rubber bracelet meaningprinted wristbandpersonalized sports braceletsbasketball silicone braceletssilicon bracelets
[Photo/VCG] China has launched cross-border partnerships with several international nongovernmental and civic organizations to create three green economic belts in countries involved in the Belt and Road Initiative. Three belts will be created using poplar trees, under a plan released by the China Green Foundation at the Belt and Road International Forum on Public Cooperation for Ecological Remediation, which was held in Wuwei, Gansu province, on Thursday. The belts are expected to start in Northwest China and connect countries in Central and West Asia, such as Pakistan, Kazakhstan, Iran and Turkey. Under the plan, a cooperative partnership will be established to encourage more exchanges of experience in developing a green economy in different countries, said Chen Shuxian, chairman of the foundation. Poplar trees now cover about 648,000 hectares worldwide, according to the foundation. Most of them are located in 17 countries involved in the BRI. China holds 61 percent of the world's total poplar tree forests, which provide important economic value to people. For example, the poplar forest covering an area of 31,840 hectares in Hotan, Xinjiang Uygur autonomous region, generates annual income of 672 million yuan ($98 million), according to the National Forestry and Grassland Administration. In Inner Mongolia's Ejin Banner, residents developed a tourism industry themed on poplar tree forests, which attracted more than 1.1 million tourists from home and abroad in 2015 and which has generated 1.4 billion yuan annually. We want to encourage more countries to improve their ecosystems through planting poplar trees. And we welcome international enterprises, both in the private and public sectors, to support the partnership through donations, said Chen Lian, vice-chairwoman of the foundation. In return, this cross-border cooperative will bring them more business opportunities. During the forum, the foundation also announced the launch of an international ecological restoration fund, drawn from donations worldwide to promote a green economy in countries involved in the BRI. Like many countries, China has been confronted with the negative impact of a deteriorating environment. It has made remarkable achievements in ecological remediation, including combating desertification and working to restore and expand forests, said Liu Zhenmin, undersecretary-general for economic and social affairs of the United Nations. He said the BRI focuses on a common development, with its goal of achieving win-win cooperation in line with the 2030 Agenda. Through the forum and the cooperative mechanism, he said, China can better share its experience with civic organizations and collaborate to advance ecological remediation in other countries.
