The second tallest building in the world is more like a vertical city than a building. Think of it like this: the 632-meter tall Shanghai Toweris a bustling mixed-use metropolis with more green space (and even more people) than many cities on the ground can boast of having.
The statistics on the building, which ranks only behind Dubai’s Burj Khalifa in height, are staggering: 521,000 meters squared of floor space, 106 elevators, a weight of 1,200 metric tons, the ability to hold 30,000 people (it really is like a small city), and the kicker—one-third of the building is dedicated entirely to green space.
One Innovation By Design entrant is Hello Compost, a proposed program in which low-income families will be able exchange compost for produce credits.
“We need to re-imagine the role of food waste from being a smelly, unattractive side effect of eating to an attractive resource for residents to positively impact their community and to help put fresh food on the table,” says cofounder Aly Blenkin.
Their study found 1,000 different types of bacteria on ocean plastic samples, including plants, algae, autotrophs, and predators. They warn that plastic is also serving as a new kind of transportation for potentially harmful bacteria looking to hitch a ride across the ocean.
Plastics like styrofoam currently take up between 25%-30% of our landfill space, and a single cubic foot of styrofoam has the same energy content as about one and a half liters of gasoline.
College pals Eben Bayer and Gavin McIntyre established Ecovative, which grows cost-effective alternatives to plastic insulation and packaging. While they were students at Rensselaer Polytechnic Institute, Bayer and McIntyre experimented with mycelium, the network of vegetative filaments in mushrooms, and realized that it could be used to form incredibly strong bonds. Essentially, the substance functions like a glue that you can grow and use to form agricultural byproducts like plant stalks and seed husks into natural alternatives to styrofoam packaging and insulation.
