City of Kwinana

Pollution in our waterways is not only dangerous and unsanitary for humans but it also affects wildlife. That’s why it is so exciting to see an initiative aimed at preventing such waste.

The Australian city of Kwinana has designed a simple and cost-effective solution to deal with the discharge of waste from drainage systems. The town has put nets on the outlet of drainage pipes.

These nets stop waste and pollutants from leaving the sewers, preventing garbage transported by rain waters from contaminating the town’s local water reserve. It is a simple filtering system and it works like a charm.

Southeast Asia braces for trash dump as China enacts waste import ban

SCMP
  • On January 1, China will no longer be accepting waste from other countries, with Vietnam, Thailand and Indonesia likely to feel the brunt of the new policy
  • Although the three countries have taken steps to deal with mounting trash, corruption and weak policies could doom them to remain buried in refuse

China, which used to be the world’s salvage king, is shutting its door to all waste imports starting the first day of the new year. The recent announcement triggered the same kind of anxiety among waste-exporting countries as in 2018, when China enacted its “Operation National Sword” policy, which banned the import of 24 types of solid waste, including plastic waste.

The 2018 policy switch caused the world’s major waste-exporting countries – Europe, Britain, the US and Australia – to scramble for alternative destinations, including

Southeast Asian

nations like Thailand, Vietnam, and Indonesia, which quickly became overwhelmed by the volume of refuse they received. Soon after, these countries began to impose their own bans and restrictions on waste imports.

With China’s latest announcement about a blanket waste ban, concerns have been raised about the effects this might have on Southeast Asian countries, where limited waste-management capacities are common.

, which borders China and was one of the countries most affected by Beijing’s 2018 waste policy, might not be ready for more imported waste. According to a national report released last month, various types of solid waste imported for manufacturing do not only not meet the national technical standard in regards to

environmental protection

but also put more pressure on waste-management services in the country.

Meanwhile, most of the domestically made solid waste processing equipment is unsynchronized, incomplete and not yet common in the country – going by the National Environmental Status Report in 2019 issued by the Ministry of Natural Resources and Environment. No specific national guidelines exist on what technology to use to treat municipal solid waste.

Since 2018, the Vietnamese government has kept a tight rein of its scrap imports through various policies, including amending the country’s technical standard to ensure only quality scrap is allowed in and cracking down on illegal shipments of thousands of containers of paper, plastic and metal scrap. Vietnam imported 9.2 million tons of scrap in the same year, a 14 per cent year-on-year increase, according to Vietnam customs statistics.

Is China building more waste incinerators than it needs?

eco-business.com

Several provinces may be investing too much in incineration, overlooking improvements in waste sorting and recycling.

The vision to make China an “ecological civilisation” has been espoused at the highest political level. It includes, among other things, efficiently using resources, reducing waste and using extracted materials in a circular manner. Reaching these objectives will require timely and well-planned investments in waste-management capacity.China has invested largely in incineration over the past decade to help manage the massive growth in the amount of municipal solid waste, produced by homes and businesses. The latest government data, from 2018, shows that 99 per cent of collected waste was managed, up from 67 per cent in just 10 years.

$10bn of precious metals dumped each year in electronic waste, says UN

A fast growing mountain of toxic e-waste is polluting the planet and damaging health, says new report

At least $10bn (£7.9bn) worth of gold, platinum and other precious metals are dumped every year in the growing mountain of electronic waste that is polluting the planet, according to a new UN report.

A record 54m tonnes of “e-waste” was generated worldwide in 2019, up 21% in five years, the UN’s Global E-waste Monitor report found. The 2019 figure is equivalent to 7.3kg for every man, woman and child on Earth, though use is concentrated in richer nations. The amount of e-waste is rising three times faster than the world’s population, and only 17% of it was recycled in 2019.

Electronic and electrical goods, from phones and computers to refrigerators and kettles, have become indispensable in modern societies and enhance lives. But they often contain toxic chemicals, and soaring production and waste damages human health and the environment, and fuels the climate crisis.

The report blames lack of regulation and the short lifespan of products that are hard or impossible to repair. Experts called the situation a “wholly preventable global scandal”.

People in northern Europe produced the most e-waste – 22.4kg per person in 2019. The amount was half as much in eastern Europe. Australians and New Zealanders disposed of 21.3kg per person, while in the US and Canada the figure was 20.9kg. Averages across Asia and Africa were much lower, at 5.6kg and 2.5kg per person respectively.E-waste contains materials including copper, iron, gold, silver and platinum, which the report gives a conservative value of $57bn. But most are dumped or burned rather than being collected for recycling. Precious metals in waste are estimated to be worth $14bn, but only $4bn-worth is recovered at the moment.

Reasons the World Wastes So Much Stuff (and Why It’s Not Just the Consumer’s Fault)

WRI.org

If you need motivation to skip the straw at lunch today, consider this: Scientists found that even Arctic sea ice—far removed from most major metropolitan areas—is no longer plastic-free. According to Dr. Jeremy Wilkinson of the British Antarctic Survey, “this suggests that microplastics are now ubiquitous within the surface waters of the world’s ocean. Nowhere is immune.” Tiếp tục đọc “Reasons the World Wastes So Much Stuff (and Why It’s Not Just the Consumer’s Fault)”

Plastic and paper scrap imports choke Vietnamese ports

Large-scale waste dumping has reportedly choked Vietnamese ports, with hundreds of containers loaded with plastic and paper scraps lying unclaimed, forcing authorities to impose a temporary ban on waste imports.

Tan Cang – Cai Mep International Co., Ltd (TCIT), a terminal services company, in a letter to shipping lines and customers, said it would suspend imports of plastic and paper scrap as a similar decision earlier by another operator, Saigon Newport Corporation (SNC), had led to overcapacity at TCIT terminals.

“From 25th of June to 15th of October, TCIT will stop receiving all imports laden containers of plastic waste,” a letter signed by general director Chang Fa Wei said. Ngo Minh Tuan, deputy head of SNC, in an official communication, claimed previously that about 5,200 containers of plastic and paper waste have been stored for 90 days or longer at its port.

TCIT Port authorities are alarmed that more than 1,132 containers with plastic and paper waste have been stacked up at the port for last few months.

“Customers are not coming forward to claim the scraps. It’s a complicated situation,” Nguyen Thai Thuong, a senior employee of TCIT, told CGTN over the phone.

“The Chinese ban on waste import is the main reason behind the surge of plastic and paper waste imports, undoubtedly.

The Chinese ban has meant a diversion to Vietnam of the now unwelcome cargo.
