1 . If you’ve never had hot pot, you’re absolutely missing out. Not only is it delicious, but it’s also a fantastic meal to share with friends or family. But it also generates a lot of waste oil. In fact, hot pot is reportedly responsible for 12,000 tons of waste oil per month just in the Chinese city of Chengdu alone. Instead of just throwing away that oil, one company decided to turn it into jet fuel (航空燃料).
Bloomberg recently published a great article about Sichuan Jinshang Environmental Technology, a company that began exporting hot pot waste oil to be turned into biofuel that can power planes. It’s not exactly a perfect solution to the greenhouse gas emissions that the aviation (航空) industry is responsible for, but it’s a step in the right direction. “Our mission is to make waste oil fly to the sky,” Zhong Guojun, the company’s vice president, told Bloomberg.
Based in Chengdu, Sichuan Jinshang Environmental Technology takes waste oil from around the city and refines it into something called industrial mixed oil. The refined oil is then exported to be turned into jet fuel or biodiesel (生物柴) by companies such as BP or Neste Oyj, the biggest producer of sustainable jet fuel in the world. And with new requirements for airlines to use more biofuel in their planes, there’s a lot of demand despite the fact that it’s still more expensive than regular jet fuel.
“When there is a demand, the supply will catch up, and the demand is already here,” said Chong Cheng Tung, Associate Professor at the China-UK Low Carbon College, Shanghai Jiao Tong University told Bloomberg. “So either you switch your fuel to green fuel, like bio-jet fuel, or you have to meet additional payments for travelling.”
Last year, Neste announced plans to spend more than $2 billion expanding its capacity to produce sustainable jet fuel. By 2026, it hopes to be able to produce 1.2 million tons of the stuff. Other companies such as Chevron, BP. and Total Energies are producing it on a smaller scale (规模) but also plan to increase their output soon.

2 . In 2022, campaign group Fashion Revolution Chelsea dye a garden for its Chelsea Flower Show presentation. An ancient craft, natural dyeing is a practice whose time has come again, with hand tie-dyed fashion also making a comeback in recent years.
The revival has been encouraged by Covid lockdowns, “which allowed people to explore the craft at home, says natural-dyeing enthusiast and teacher Susan Dye. It’s unlikely, though, that the practice would have caught on in quite the same way if not for a continually growing discomfort about fashion’s heavy footprint. From carbon emissions to animal cruelty, fashion is under considerable inspection. “Put it this way, 97% of dyes used in the industry are petrochemically (石油化学产品) based,” says sustainable fashion consultant Jackie Andrews, who helped advise the UN Ethical Fashion Initiative. We’ve got net zero targets which mean we’re going to have to remove all those petrochemicals from the manufacturing cycle.
Fashion is a huge polluter. According to the UN Environment Program, the industry is responsible for up to one-fifth of all industrial water pollution—due to the fact that most clothes today are produced in poorer countries where regulation is weak and enforcement weaker. Waste water is dumped directly into rivers and streams, poisoning the land as well as the water sources of people and animals who rely on them.
It’s easy to see why someone who cares about people, planet and animals, as well as clothes, might turn to natural plant dyeing. From the beauty of the raw materials—often wild plants-to the property of only bonding with natural fiber like cotton and linen (亚麻布) from the minor footprint of recycling old clothing that has grayed or faded over time to the vibrant and long-lasting dyeing results, plant dyeing feels like a quiet act of rebellion. This is why, while beginners start with simply changing their clothes’ color, new worlds open. Many of today’s natural dyers grow their own dye plants, run local community workshops, and advocate for change in industrialized fashion systems and beyond.
