We all agree that we should recycle more — at home, in the office or when out and about. But for materials to be recycled, they first need to find their way to the right waste stream. 【小题1】 This is what the process of sorting allows us to do.

For effective recycling we need effective sorting. And this needs to happen first, in our own home and second, in sorting plants to which waste collected from our doorstep is taken. When you put a plastic bottle in the right recycling bin, you are helping sort recyclables. So the right material can be fed into the right recycling process. 【小题2】 They can be a loss of valuable resources from our economy.

【小题3】 For instance, in Brussels, Belgium, consumers put plastic packaging, cans and beverage cartons in blue bags designed for recyclable packaging; paper in yellow bags for recycling; and glass needs to be taken to specific collection bins. Somewhat differently, in Vienna (Austria), citizens can expect their paper, metal, glass and plastic to be separately collected in different weeks of the year. 【小题4】 In this way, they can sort their recyclables at home more effectively.

Once recyclable materials are collected from your doorstep, they are further sorted in specialized facilities which ensure the quality of the recycling process. 【小题5】 Traditionally, sorting has been done either manually with workers sorting what can be recycled and picking out the materials to be discarded or mechanically. Today, however, new technologies are being developed in order to speed up the process of sorting but to also yield better results. Exciting technologies using magnets or optical systems are being used to effectively sort materials so more of it can be recycled.

Flip-flops (人字拖) are the most popular type of shoe in the world. They’re comfortable, they’re easy to wear and they’re inexpensive. Unfortunately, most of them are also terrible for the environment. In Kenya, this is a huge problem, and around 90 tons of flip-flops wash up on its shores annually.

In the late 1990s, when Julie Church was working as a marine (海洋的) conservationist in Nairobi, she found an entire beach “just covered in flip-flops”. Around that time, Church also noticed children making toys out of the thousands of flip-flops that had made their way to the country’s beaches. She began working with the kids’ mothers to encourage them to not just collect the shoes, but also turn them into artworks. The families could then sell this art at local markets, providing another means of income.

The idea took off, and in 1998, Church founded Ocean Sole as a nonprofit. This year alone, the organization has upcycled more than 750,000 flip-flops and collected more than 47,000 kilos of waste. Additionally, Ocean Sole directly impacts more than 1,000 Kenyans, many of whom work as flip-flop collectors or artists, and contributes 10% to 15% of overall income to career and educational programs for residents, as well as beach cleanup and conservation efforts.

Ocean Sole is continuously growing and looking to keep waste off Kenya’s beaches and out of its water. When it comes to growing the Ocean Sole organization, Church has three “mantras (真言)”: trust to trade, trade to awareness, and awareness to protection. Church would like to put together toolkits and other resources to bring this concept to other places around the world that have similar problems. Ocean Sole is also encouraging companies to use more eco-friendly materials when making flip-flops. “I think it’s time for us to start looking for an alternative shoe, or an alternative material, to fit that kind of fashion need,” Church has said. “Our products need to develop.”

Xu Hai’ou has spent most of her life promoting environmental protection work in Beihai, a coastal city in the Guangxi Zhuang autonomous region, by cleaning beaches, protecting mi-grant birds and recycling kitchen waste.

Though her family originally comes from the eastern province of Shandong, the 60-year-old was raised in Guangxi and moved to Beihai for work at age 23, directly after graduating from college. Before she retired, she worked as a reporter for the Guangxi Daily Media Group, a news outlet in the region. In her free time, she became involved in voluntary work.

“In initially, in the 1990s, I helped impoverished children in Guangxi’s rural areas obtain financial aid from donors in Hong Kong, and set up my own NGO in 2004. At the time, it was Beihai’s only nonprofit social organization involved in volunteer work,” she said, “It’s very enjoyable to do this charity work and I have made many friends through it.”

She said her NGO focuses on environmental protection work and organizes a range of voluntary activities, including cleaning up beaches, and protecting mangrove forests and migratory birds.

In 2008, the organization joined a marine life protection event supported by the central government, the UN Environment Programme and the Global Environmental Facility.

Xu and her colleagues at the association arranged a number of voluntary events such as raising awareness of marine biodiversity among local residents and students, and beach-cleaning activities to help promote understanding of the need to protect marine animals and plants.

“Undertaking voluntary activities or charitable work has become my mission, and I want to contribute my own efforts to the nation’s environmental protection work, even if they only produce a small improvement. However, protecting the environment is very hard work. which can’t be done by a single person. I sometimes feel like my ability falls short of my wishes.”

According to Xu, her NGO is currently promoting the classification of waste in Beihai and recycling kitchen waste into compost. “We have mature technologies, but still face difficulties in promoting the program because many residents lack awareness of environmental protection. We hope the government can figure out better ways of managing the garbage after we classify it to make full use of this ‘waste’.”
