Ditch Disposable

Choose reusable

Ditch Disposable is a campus-wide campaign led by the University of Hong Kong Sustainability Office that aims to reduce plastic waste by targeting disposable plastics across campus. 


The Plastic Problem

Disposable plastic is cheap, convenient and used every day, yet the majority of it ends up in landfills or the natural environment, releasing toxins, and harming wildlife and eventually us. Globally we produce more than 300 million tons of plastic a year, half of which is intended for single-use.

We could be eating plastics on a daily basis. Despite a negligible impact on human health at current intake levels, researchers suggest that as global plastic waste continues growing, our ingestion level will increase. They also warn us about the health risks associated with microplastics, which are hard to detect and currently understudied. These small particles (≤1.5 µm) could penetrate capillaries and enter human organs.

Plastics also cause harm to wildlife through ingestion, entanglement and toxicological influence. Wildlife may mistakenly ingest plastic debris as they feed, or ingest them through the food chain.
