Gen Green

St Paul’s School, London – Years 7-9

St Paul’s School, London: Gen GreenThe problem we are looking to address is the amount of recyclable waste that sits rotting in landfills because we don’t put our litter in the correct bins.

Plastic waste is harming the environment, wildlife and humans. It kills more than 1.1 million seabirds and animals every year. And estimates say more than 90% of all birds and fish have plastic particles in their stomach. Our automated recycling bin can help ensure plastic doesn’t end up in the environment.

Our SARB (self-automated recycling bin) sorts different types of waste automatically. The person puts the item in the bin and a PIR sensor attached to our Raspberry Pi detects it. This sends a notification to the Camera Module(v2), which scans the object and uses an image recognition software known as TensorFlow (coded into our Raspberry Pi 4b) to work out whether the item is recyclable or not. A motor, lever and pivot then move the item to the right bin.

By taking the effort out of recycling, SARB can reduce the amount of waste going to landfill and incineration. And, as recycling saves energy, SARB also reduces greenhouse gas emissions, which helps tackle climate change.
