An Underground Lunch Delivery Train Comes to the Atlanta Suburbs

Entrepreneurs are encouraging reuse models like return-from-home systems to transition towards a circular economy without single-use plastics. In this model, consumers pay a deposit to use takeout boxes, cups, and other containers. They get their deposit back when the containers are picked up from their home by a courier.

Landscaping businesses in California are trading in the typical tools and chemicals for goat herds. The practice of bringing in goats to munch on unwanted vegetation, called targeted grazing, is cheaper and more environmentally friendly than traditional landscaping.

Gipave is a new type of asphalt technology that combines plastic waste with bitumen, a material already used to pave roads, to make recyclable road surfaces with longer lifespans and reduce emissions from road work by 70%.

Although urban cities have a variety of options for food, not all food is affordable or healthy. New York City has developed urban agriculture projects, from rooftop gardens to “warehouse hydroponic systems.” The South Bronx’s BLK ProjeK’s Libertad Urban Farm serves the local, low-income community and empowers its women leaders with self-sufficient sustainable food.

Three startups in Houston are using a technique similar to fracking, a practice used in the oil and gas industry, to store renewable energy without batteries. They use excess renewable energy to pump pressurized water into manmade caverns underground. When energy is needed, they open the caverns, sending the water back to the surface to turn a turbine and generate power.

Brick-making businesses in Uttar Pradesh, India, are switching from coal to solar panels to power their kilns. The swap allows them to meet more than their electricity needs, also supplying energy to their employees’ huts, while reducing emissions.

The California-based startup Magrathea Metals is producing magnesium with renewable energy to make the process less expensive and material-intensive. The company aims to make the more environment-friendly metal competitive with steel and aluminum.

Eversource Energy, a utility company in Massachusetts, installed a networked geothermal system that provides heat for residential and commercial buildings across the city of Framingham. The connected system allows excess heat from one building to be redirected to another that needs it. It’s the first of its kind in the United States.

A utility company in Framingham, Massachusetts, worked with climate advocates to build a unique geothermal heating and cooling project that spans a whole neighborhood. A group of residential and commercial buildings share the infrastructure necessary to harness stable underground temperatures for heating and cooling, which reduces their greenhouse gas emissions and energy bills.

Artificial intelligence tools are helping the solar energy company Solstice better serve community solar subscribers and make projects more inclusive for low-income households. The tools use data to predict when subscribers might be facing problems that will likely lead to them leaving the project, such as delays or billing confusion, and vet subscribers based on whether they are likely to pay their bills instead of using their credit scores.
