On Nov. 21, the University of Maine Advanced Structures and Composites Center (ASCC) unveiled BioHome3D, the first 3D-printed house made entirely with bio-based materials. BioHome3D was developed with funding from the U.S. Department of Energy’s Hub and Spoke program between the UMaine and Oak Ridge National Laboratory. Partners included MaineHousing and the Maine Technology Institute.

SHARM EL-SHEIKH, Egypt — Diplomats from nearly 200 countries concluded two weeks of climate talks Sunday by agreeing to establish a fund that would help poor, vulnerable countries cope with climate disasters made worse by the greenhouse gases from wealthy nations.

The decision on payments for loss and damage caused by global warming represented a breakthrough on one of the most contentious issues at United Nations climate negotiations. For more than three decades, developing nations have pressed rich, industrialized countries to provide compensation for the costs of destructive storms, heat waves and droughts linked to rising temperatures.

As the problem of discarded plastic polluting our ocean grows year on year and with no solutions forthcoming to prevent it, many communities are taking it upon themselves to retrieve what debris and waste they can from their own waterways.

EVERY YEAR, PEOPLE in the United Kingdom throw away around 96 billion pieces of plastic packaging—an average household tosses 66 pieces every week. Almost half of this packaging waste ends up being incinerated, while a quarter is buried in landfills, according to a May 2022 survey by Everyday Plastic and Greenpeace. The scale of the waste is hard to fathom.

“The plastics crisis can be daunting,” says Insiya Jafferjee, the CEO and cofounder of packaging company Shellworks. Speaking at WIRED Impact in London this November, Jafferjee said that even small, seemingly simple pieces of plastic—such as scoops included in baby formula packaging—result in hundreds of millions of pieces of plastic waste every year. Shellworks was created to start making a dent in the amount of plastic packaging that gets thrown away. To do so, Jafferjee and cofounder Amir Afshar developed an entirely compostable material that can be used to package goods.

SINCE CONTROVERSIALLY BEING awarded the 2022 FIFA World Cup back in 2010, Qatar has promised that the soccer tournament—which kicks off on November 20—will be carbon-neutral. This would be an impressive feat for any major sporting event, given the need to build new infrastructure, accommodate teams and fans, move them around, and run the actual games. But it is an even more daunting challenge in this small Gulf state. Qatar is heavily reliant on fossil fuels, is blisteringly hot, and had barely any suitable facilities prior to the event.

Nevertheless, its organizers insist the tournament will be carbon-neutral. Skepticism about this claim has understandably been rife, as have allegations of greenwashing. Qatar’s sustainability strategy, broadly speaking, relies first on minimizing emissions as best it can—which has obvious limitations, given the need to build stadiums from scratch and operate them with packed crowds in the desert—and then compensating for any remaining emissions using carbon credits. The practice of offsetting draws criticism at the best of times, but the methods and calculations used to get the Qatar World Cup to net-zero are particularly dubious.

FOR THOSE OF us with seasonal depression or anxiety, houseplants can offer immense comfort. In fact, adding loads of leafy things to your home has been shown to boost mood and relieve anxiety — in short, they help us (metaphorically) breathe a bit easier. But now, a specially designed plant can literally clear the air.

A Paris-based startup called Neoplants aims to harness the natural air-filtering properties of plants and turn them up to 11. By genetically engineering both a pothos (Epipremnum aureum) plant and its associated root microbiome, the team behind Neoplants created an organism they claim is capable of doing the air-purifying work of up to 30 plants. The company’s first high-tech houseplant, called Neo P1, recently hit the market.

According to the National Association of Home Builders, building a single 2,000-square-foot home at a job site creates over 8,000 pounds of waste. Hundreds of millions of tons of construction waste end up in landfills yearly.

Unlike traditional homes built at the job site, Clayton manufactured and modular homes are built off-site in a climate-controlled facility and transported to the home site for set up. This means the team can closely monitor material usage and reduce waste while ensuring their processes and workspaces are efficient.

In the southern Indian city of Tuticorin, locals are unlikely to suffer from a poorly risen cake. That’s because a coal-fired thermal power station in the area captures carbon dioxide and turns it into baking soda.

Carbon capture schemes are nothing new. Typically, they use a solvent, such as amine, to catch carbon dioxide and prevent it from escaping into the atmosphere. From there, the CO2 can either be stored away or used.
