Phra Mahapranom Dhammalangkaro, abbot of Wat Chak Daeng, with the solar-powered Hippo waste-collection vessel behind him. When he began his campaign against plastic, he found a novel way to get people to send monks their waste: ‘People can make [Buddhist] merits by giving us plastic bottles, bags and paper.’
Today’s story shows a good way to reduce current plastic problems, even though we know that long-term, we need to stop producing plastic. You can collect it and turn it into other products, but when the new products break down, we still have plastic.
Claire Turrell writes at the Guardian from Bangkok, ” ‘Once upon a time this river was filled with fish; now, nothing swims in it any more,’ says Wat Chak Daeng temple’s abbot, Phra Mahapranom Dhammalangkaro, as he looks out over Bangkok’s Chao Praya River.
“As a novice monk in the 1980s, he remembers seeing children playing in the river and people scooping up handfuls of water to drink. But when he became abbot of Wat Chak Daeng more than 25 years later, those bucolic images were a thing of the past. Instead, when he arrived at the 240-year-old temple, he was saddened by the sight of the dirty river and the rubbish-strewn grounds surrounding it.
“Dhammalangkaro knew that if nothing was done, the situation would only get worse. He built a recycling centre in the temple grounds, which evolved from collecting a handful of bottles to upcycling 300 tons of plastic a year. His biggest problem was that he was unable clean the river itself.
“But then he met Tom Peacock-Nazil, chief executive of Seven Clean Seas, an organization that finds solutions for plastic pollution. Last week the two men launched the Hippo, a solar-powered boat, which aims to remove [millions of pounds] of plastic a year from Bangkok’s busiest waterway. …
“The Chao Phraya River is the largest waterway flowing through central Thailand. It stretches more than 230 miles from the northern Nakhon Sawan province to the Gulf of Thailand and is home to critically endangered species such as the Siamese tigerfish, giant barb and Chao Phraya giant catfish.
“In Bangkok, it is an artery for a network of water buses, ferries and wooden long-tail boats. But it’s not just carrying people. According to research by the Rotterdam-based non-profit organization Ocean Cleanup, the Chao Praya River carries 4,000 tons of plastic waste to the sea every year. …
“The Hippo’s design is simple and effective. A boom on the vessel funnels the floating plastic from the river on to a solar-powered conveyor belt. This then hauls the rubbish out of the water and drops it into a dumpster hidden under its roof.
“The tangled mass of water hyacinths, food containers, plastic bottles and bags is then sorted by hand and recycled at the plant in the temple. …
“Chalatip Junchompoo, a director of the Marine and Coastal Resources Research Centre, believes the Hippo’s presence will have an important impact by raising awareness of plastic waste. She views it as a welcome addition to its network of river booms and rubbish-collection boats. …
“Thailand is aiming to have all plastic recycled by 2027, up from 37% now, according to the Pollution Control Department. Plastic that cannot be recycled is, where possible, used for refuse-derived fuel. …
“While sponsorship has helped cover the running costs of the Hippo, future expenses and maintenance will be paid for with plastic credits, which companies can use to offset their plastic footprint.
“In Wat Chak Daeng, some of the plastic is sent to a factory to be converted into fabric. The fabric is then sewn by volunteer seamstresses at the temple into saffron-colored robes for the monks, as well as blankets and bags. …
“The monks can upcycle multilayered plastic, which is seen as challenging to recycle, thanks to a new machine that uses a chemical recycling method known as pyrolysis to break plastic down into oil. Any organic waste is converted into fertilizer using two industrial composters.
“The Hippo has created the final link in Wat Chak Daeng’s circular economy. Now the aim of the team is to build more Hippos to tackle other polluted rivers elsewhere in Thailand and south-east Asia.
“Peacock-Nazil says that addressing rivers alone is not the solution. ‘We need to work onshore and in riverside communities to make sure they have the infrastructure needed to stop plastic leaking into the environment in the first place,’ he says.
“Seven Clean Seas, as well as extending its reach in Bangkok, plans to create educational programs at a local level and would like to offer the Hippo as a floating laboratory for universities in the future.”
