The worlds largest waste-to-energy plant is being built in Shenzhen, China.

Shenzhen has had problems with illegal discarding of trash and its many over-sized landfills, notably when a waste spill, in December of 2015, caused a landslide burying 33 buildings and killing dozens.

Many countries burn trash and while it might not be the best solution, its something that’s drastically needed in the most populous country in the world.

Not only will it help the city potentially save lives, the energy plant is expected to produce usable electricity from a third of the trash. The plant will have around 44,000 square meters of solar panels on its mile long roof and it might even provide electricity to neighboring cities.

It should be noted that this plant might not be environmentally safe, though its not a solution for reusable energy, it’s a solution to the waste problem in the city. The city has reportedly been burning 5,000 tonnes of waste in a single day. This plant will help the China with one of its serious issues. It’s expected to be running by 2020 and is just one of 300 plants that are planned to be built around the country.
