Plastic recycling in Taiwan: recycling plastic is not a yes or no story, let alone when it comes to practices in Asia. Recently I came across an article, which describes the plastic recycling in Taiwan, a beautiful green island in a continent with a contradictory and often problematic background when it comes to green and sustainable practices.
As much as we know that products made from recycled plastics are not recyclable anymore, a lot of us put very high hopes on the recycling industry. To a large extent, we are right as recycling by default is perceived as undeniably good. It is, however, not often that we see solid ideas behind plastic recycling or the process done on a large scale. Sure, plastic polymers require greater processing than many other materials, the common practices are: monomer recycling, thermal depolymerisation, heat compression, etc. Bear in mind also that different plastics can often not be recycled at all due to the difference in molecular structures (weight) and melt temperature. In short, plastics are relatively nasty products that contaminate the environment heavily – throughout their life-cycle.
Hope always dies last and we want to hear the good news also. There is a case of plastic recycling in Taiwan, which turns the recyclate into literally green gold. How do they do it?
From fake hair to football jerseys and building bricks, plastic recycling in Taiwan means breathing new life into its massive plastics waste, creating a booming new business at the same time as it aims to go green. The island started recycling plastic more than a decade ago amid growing environmental concerns, and today it boasts about 73 percent recycling rates, according to the cabinet’s Environmental Protection Administration. Last year, nearly 180,000 tonnes of used plastic were collected and turned into raw materials worth 4.5 billion Taiwan dollars (140 million US), which cut down garbage disposal costs and carbon dioxide emissions, it said.
“Plastic recycling in Taiwan can be produce many products such as garments, flower pots, wigs and zippers,” said Ma Nien-ho, a spokesman for the administration’s recycling fund management board. “We are not only protecting the environment but also making money,” he said.
Taiwan took pride in the so-called “eco-fabric” that was used by local companies to make the jerseys for nine teams competing in the recent football World Cup in South Africa. Each jersey, made from eight plastic bottles melted and processed into polyester, is 13 percent lighter than traditional fabric and can absorb and disperse sweat more quickly, according to Taiwan Textile Research Institute. “The production process is also more environmentally friendly as it takes less water and energy to dye the shirts when using coloured bottles,” said Alex Lo, managing director of Super Textile Corporation.
Super Textile, a leading Taiwanese maker of eco-fabric, started exporting to the United States and Japan in recent years, which gave a boost of up to 10 percent to its business, Lo said. “The response has been much warmer in the past two years due to rising awareness on global warming and fluctuating cotton prices,” Lo said. “We are optimistic that the World Cup publicity will help stir up more demand.” Taiwan, a small island that consumes about 4.5 billion plastic bottles annually, is seen as having an advantage in manufacturing eco-textiles through lower transportation and recycling costs. Tzu Chi Foundation, one of the island’s largest charity groups, runs 4,500 recycling stations across Taiwan with the help of about 70,000 volunteers who collected 12,000 tonnes of used bottles last year.
The foundation has distributed more than 300,000 blankets made from plastic bottles since 2007 for relief uses at home and abroad, it said. And perhaps in the near future houses built from recycled plastic bottles will mushroom across the island after “Eco Ark”, the world’s first such building, is unveiled in November. “Eco Ark” — a three-storey 24-metre (78-feet) high exhibition hall due to debut at the Taipei International Flora Exposition, is built from 1.5 million recycled plastic bottles and cost 300 million Taiwan dollars. “The bottles are processed to make bricks that can resist earthquakes, wind and fire while providing the building with natural lighting to save electricity,” said its architect Arthur Huang. “The ‘polli-bricks’ are also less expensive than conventional materials like wood and glass so the construction cost is much lower.” Huang said his firm is currently building a luxury boutique hotel and several factories and corporate buildings with the bricks. “Just imagine if we can replace all the steel roofs in the buildings in Taipei with light transparent polli-bricks. That would make the city look more beautiful.”
With all of the above said, many countries should learn from plastic recycling in Taiwan and the green practices that make money as well. This is the essence of sustainability – when all financial, environmental and communal benefits are met.
