Singapore government focuses on recycling, but residents fail to play their part

Aza Wee Sile CNBC.com 15 Nov 16;

Singapore has impressive public waste-management systems, but there's just one problem - its residents aren't pulling their weight when it comes to household recycling.

The land-scarce Asian city-state generated about 8,400 tons of solid waste a day in 2015, but has just one offshore landfill space to bury all its trash. The landfill "island," called Semakau, was created in 1999 and extended in 2015, with enough space to meet Singapore's waste disposal needs until at least 2035.

Singapore gets by with so little space for rubbish through an innovative waste management process, in which it recycles about 60 percent of its solid waste and incinerates 38 percent of its total waste in waste-to-energy plants. Just 2 percent of the non-incinerable solid waste and the ash from the incinerator plants are buried in the landfill.

But this isn't due to a heroic environmental effort from Singaporeans. Households recycled just 19 percent of their waste in 2015, down from 22 percent in 2010.

Man crushes empty drink cans, which were collected to be sold off as scrap metal to recycling companies in Singapore.
"The lack of awareness and indifference only partly explains the absence of recycling habits [in Singapore] ... In most cases people do not recycle simply because they are not required to do so," said Tong Yen Wah, co-director of the Energy and Environmental Sustainability Solutions for Megacities program at the NUS Environmental Research Institute.
Recycling is easy enough in Singapore. There are shared recycling bins at every block on the island's public housing estates, with a minimum of three weekly collections. Private landed properties have one recycling bin each, with weekly collections.

"It's really not that difficult for residents to place their recyclables in these bins," Melissa Tan, chairman of the Waste Management & Recycling Association of Singapore, told CNBC. "What is needed is a mindset change."

"I personally think Singaporeans have been too pampered by an efficient government...We need to further develop our recycling culture so that Singaporeans make an extra effort to recycle more instead of simply throwing things away," Tan added.

Aside from the government measures in place to dispose of their rubbish, Singapore has long relied on a network of rag-and-bone men, known as "Karang Guni men," who go door-to-door in housing estates, paying residents by weight for newspapers, used clothing or electronics waste, which they then sell to specialized markets or junkyards.

Lynn Su-Lin, a recycling advocate and environmentalist, told CNBC the reason she believed recycling hadn't caught on in Singapore was because of "the lack of social consciousness in thousands of Singaporean families."

"Singaporeans also have a love affair with plastic bags, always taking new plastic bags because it comes at no extra charge," Lynn added.

Experts say that Singapore should look to emulate East Asian countries including South Korea and Japan, which have cultivated successful public recycling behaviors through unorthodox measures.

For example, in South Korea it is mandatory for food waste to be separated by households so it can be recycled into animal feed or compost. There are also high-tech food waste disposal systems that weigh the food waste and charge residents based on the weight of disposed food waste. The country managed to cut its food waste from 5.1 million tons in 2008 to 4.8 million tons in 2014, official statistics show.

In Southeast Asia, Malaysia has recently focused on recycling, by introducing compulsory waste segregation in June. Penalties for residents who don't comply include fines of up to 500 Malaysian ringgit ($120).

The NUS Environmental Research Institute's Tong said the fines in Malaysia for non-recycling offenders were more of a deterrent than any other measure. But he said implementing penalties in Singapore might not work as well because most residents lived in high-rise buildings with rubbish chutes inside their apartments that led to shared bins, which meant that identifying individual offenders would be difficult.

"What [Singapore] can do instead is to make people pay according to the amount of garbage they produce, known as the pay-as-you-throw or polluters-pay principle," Tong said, adding that such measures could be combined with a save-as-you-reduce program, in which people do not pay to have their recyclables collected.

In 2015, the island state launched a blueprint with targets for a more sustainable Singapore. Some of the new measures to encourage household recycling included dual chutes for waste and recycling in new public housing blocks.
