Two dozen children fanned out along a creek near their elementary school, filling sacks with litter left by residents of the concrete shacks lining the waterway.
When they’d finished the morning clean-up, the students emptied a large garbage bag to study its contents. A stream of shiny plastic scraps spilled onto the school’s driveway.
Bearing the names of familiar international brands of coffee creamer, biscuits, laundry detergent and candy, the discarded packaging illustrated one of the biggest environmental challenges facing Asia’s booming cities. The palm-sized packets known as sachets have exploded in emerging economies, allowing low-income consumers to buy single servings of almost any product.
But the packaging cannot be easily recycled, and in cities like Manila with spotty waste collection, the used pouches have piled up in empty fields, collected in sewers and spilled into rivers and oceans – adding to a glut of plastic waste that Asian countries have begun to regard as an environmental crisis.
“For people who live on a day-to-day basis, sachets are a reality of life – but they are also one of the biggest waste problems we face,” said George Oliver De La Rama, a spokesman for the Pasig River Rehabilitation Commission, the government agency overseeing the cleanup this month.
As environmental groups sound the alarm over harmful plastic debris, Western consumer goods companies are searching for ways to reduce the use of sachets and make them easier to recycle. In Manila, manufacturers are investing in plans to turn used plastic into bricks, tiles and classroom chairs.
Meanwhile, the number of sachets in the environment continues to explode.
The Philippines, an archipelago with more than 105mn people spread across 7,600 islands, consumes about 59.7bn sachets every year, according to the Global Alliance for Incinerator Alternatives, or GAIA, an advocacy group. That’s enough to cover all of metropolitan Manila – or roughly half of Los Angeles – in one foot of plastic.
For consumer goods giants, sachets were “a brilliant marketing tactic to capture the low-income market and good for brand visibility, but no one thought of the consequences,” said Von Hernandez, a Philippine environmental activist and global coordinator of Break Free From Plastic, an advocacy group.
Since Americans Harold Ross and Yale Kaplan patented the flexible, single-use plastic food pouch in 1955 – making the first ketchup and soy sauce packets possible – multinational corporations have used sachets to sell tiny quantities of every conceivable product.
The first to realise the potential of sachets in Asia was a family-run Indian company called KavinCare, which in the early 1980s introduced 0.3-ounce pouches of shampoo, good for one wash.
Sold for pennies, it was such a hit with villagers – some of whom had never used shampoo before – that competitors began packaging salt, talcum powder, toothpaste, soap and skin cream in small, throwaway packages.
Management expert C K Prahalad, in his 2004 book The Fortune at the Bottom of the Pyramid, wrote that companies could realise $13tn in profits every year by selling to the half of the globe that lived on less than $2 a day. A sachet revolution rippled across the developing world: brightly coloured packets with corporate logos dangling from roadside stalls and market shelves everywhere, promising safe and hygienic products for all.
But all those pint-sized pouches ushered in a waste nightmare.
Their complex construction – multiple layers of polymers, aluminium and films designed to keep products fresh in soggy tropical heat – renders sachets almost impossible to recycle. Although small-scale initiatives in the Philippines and elsewhere are attempting to repurpose sachets, the vast bulk of the waste must be dumped in landfills or incinerated – but the low-income neighbourhoods that rely most on the pouches are often the ones least likely to have reliable trash collection.
In Philippine cities, waste pickers who gather plastic for recycling leave sachets behind because they have no value.
“The industry knew that there was little collection or recycling capacity when they started selling here,” Hernandez said. “We are shouldering the burden of their product – they are profiting at our expense.”
Scientists Laurent Lebreton and Anthony Andrady recently estimated that in 2015, metropolitan Manila – a coastal megacity of more than 15mn people – generated at least 810,000 metric tonnes of plastic litter that wasn’t properly disposed, the most of any urban area in the world.
In their analysis, the Philippines trailed only China and India in the quantity of plastic debris it allowed to seep into the ocean, where scientists believe it is endangering aquatic species and contaminating the food chain.
“They’re very light, easily blown and carried by the wind and the water – so there are coastal communities that are just inundated with sachets,” said Beau Baconguis, regional plastics campaigner for GAIA.
The group recently analysed collection efforts in 21 Philippine cities and found that sachets made up more than half of all household plastic waste. The lion’s share of consumer packaging came from just a handful of companies – including Nestle, Unilever and Procter & Gamble.
Each company has announced plans to phase out hard-to-recycle plastics over the next decade. Unilever – maker of Dove and Vaseline – has said it will reduce its use of plastic by 2025 by enhancing collection efforts, increasing the use of paper and other alternatives and introducing new delivery models such as refill stations.
Activists say the Philippine government has failed to enforce its waste management law, which requires local governments to collect trash from every neighbourhood and prohibits manufacturers from using “non-environmentally acceptable” packaging material.
Philippine officials have resisted toughening rules around plastic products, saying they don’t want to harm consumers. At an event on marine pollution this year, Ricardo Calderon, a senior environment department official, said “the sachet economy ... is basically part of (economic) development.”
Despite environmental concerns, forecasters believe the global market for plastic packaging will continue to grow by more than 3% annually, reaching $269bn by 2024, according to one analysis.
“You can’t change from plastic packaging without a clear substitute,” said Bert Guevara, vice-president of the Philippine Alliance for Recycling and Materials Sustainability, a consortium of manufacturers and industry groups that includes Unilever and Coca-Cola. The group opposes proposals to ban single-use plastics or restrict sales of sachets.
“We have over-demonised plastic, and now people want to solve the problem in one or two years,” he said. “We are pushing for science-based solutions.”
In the industrial Manila suburb of Paranaque, GAIA and local authorities recently opened a factory to manufacture parking bumpers and bricks using shredded sachets.
The “eco-bricks” – made of sand and gravel, mixed with 15-18% sachets – are said to be five times as strong as standard bricks, Guevara said, and could soon be used in city construction.
Over the noise of jets landing at Manila’s nearby international airport, Guevara touted the potential of a 20-foot mound of sachets rising from one corner of the tin-roofed warehouse. Once it gets going, he said, the facility could process 1 tonne of sachets per day.
That sounds like a lot, but consider this: According to government statistics, the Philippines generates more than 4,600 tonnes of plastic waste daily.
“We have to start somewhere,” Guevara said. - (Los Angeles Times) Tribune News Service
