Japan has been one of the top leaders in the world over the past 10 years when it comes to recycling plastics. In 2010, 77 percent of plastic waste was recycled, a gain of 4 percent from 2006, putting Japan far ahead the United Kingdom’s 38 percent and a 20 percent recycling rate for the United States, according to data from the country’s Plastic Waste Management Institute (PWMI). Japan’s experience may hold vital lessons for other countries and industries struggling to meet stakeholder demands for broad recycling programs.
In 1997, Japan passed several recycling laws obliging both businesses and individuals to separate plastic waste. A lack of landfill space has been a major drive for the country to put these laws into effect as the country’s large population (127 million) continues to expand within its increasingly crowded urban areas.
PWMI reported that in 2006, “Japan recycled 2.1 million tons of plastic waste, while 4.8 million tons undergoes so-called ‘thermal recycling’, which includes conversion into useful chemicals and burning to generate energy.”
Polyethylene terephthalate (PET) bottles have to be separated from other plastic wraps and containers in most households, and the PET bottle must have its label removed and discarded before it is recycled. In 2010, 72 percent of PET bottles were recycled in Japan, compared to 29 percent in the US and 48 percent in Europe.
Japan uses the recycled materials in “textiles, sheeting, industrial materials and household items” like egg boxes. Japan also exports significant amounts of recycled plastics to China, Hong Kong and elsewhere in Asia, where the waste is refabricated for use in toys and games.
“Japan has been able to make progress in plastic recycling because waste-processing agencies have won the support of manufacturers,” Takushi Kamiya said, a PWMI spokesman.
“We are looking at ways to deal with what’s left over, but it’s difficult to imagine at this stage that we’ll get the recycling rate to 100%,” he said. “But I think we do very well compared with other countries.”
Kevin Carroll, the representative director of EA International, explains part of the issue with Japan’s substantial plastic waste.
“Japan differs from other countries in that it tends to overwrap,” he said. “You buy a bento boxed lunch and it comes in a plastic box with a lid, and then it’s put into a plastic bag. Lots of other foodstuffs are the same.
“There’s a tremendous amount of plastic around. The real problem is with household plastic, a lot of which gets burned or buried. The amounts involved are phenomenal.”
Japan has gone to great lengths to ensure recycling happens, working to involve everyone from manufacturers to consumers through legislation like the Home Appliance Law. It has also sparked the creation of innovative companies. Food company Ajinomoto, for example, has revealed a plastic bottle made entirely from recycled PET, which it anticipates using 4,500 tons of in its drink bottles annually.
In Yashiro, resource recovery plant Panasonic Eco Technology Center (PETEC) recycles air conditioning units, washing machines, refrigerators and television sets daily. Beginning operations in 2001, PETEC has recycled more than 1.4 billion appliances, “producing enough materials to manufacture 95 jumbo jets, the equivalent of 81 of the Great Buddha statue at Nara and 158,000 cars from reclaimed aluminium [sic], copper and steel.” PETEC has a system to also capture noxious gases, and recover resins such as polypropylene and polystyrene.
When a consumer drops off used appliances they have to pay a small recycling fee and purchase a ticket that shows collectors the fee has been paid.
Product managers and engineers who work for the manufacturers that build the appliances visit PETEC regularly “so they can pick apart the very products they design,” thereby finding flaws in their designs and creating better products that potentially create less waste. As an example, “on a line of air conditioning units, product designers realized that if they laser printed the company logo instead of embedding and pasting a small tablet sized piece of plastic, the recycling rates of such components would increase dramatically.”
PETEC holds an 85 percent recycling rate and receives approximately a 10 percent ROI. The company believes their efforts are a prime example of ways to create new revenue opportunities while working to minimize the impact of appliances and consumer purchasing on the environment.
Hundreds of millions tons of consumer electronics and home appliances are discarded globally each year, resulting in heaping mountains of electronic waste, or e-waste, that have long been a focus of environmental stakeholders such as the Basel Action Network and Greenpeace. Efforts to create recycling programs to counter e-waste have had mixed success in the EU, U.S. and elsewhere.
