A solution for Hong Kong’s plastic waste crisis: turn it into fuel

July was a critical month for plastic pollution. Plastic waste now has catastrophic implications for Hong Kong, and the planet. In July, a study by the University of California, Santa Barbara provided the first global analysis of all mass-produced plastics. Media reports said plastic threatened a “near permanent contamination of the natural environment”, and called the threat a “crisis comparable to climate change”.

The amount of plastic created since 1950 had increased exponentially, from 2 million tonnes to 8.3 billion tonnes in 2017, and is projected to reach 34 billion tonnes by 2050. We are creating a problem that cannot go away: the study found that, in 2015, of the nearly seven billion tonnes of plastic waste generated, only 9 per cent was recycled, 12 per cent incinerated, and 79 per cent accumulated in landfills or the environment.

The devastating impact of plastics on the marine environment can be seen in the many internet videos showing whales, turtles and sea birds killed by ingesting plastic in the sea. The intrusion of plastics into the food chain on both sea and land is well documented.

This July, Hong Kong had unusually high rainfall, which resulted in a visible increase in plastics washed into our waters. Several non-governmental organisations and community groups have been cleaning up beaches; much of the rubbish is plastic.

While their efforts are necessary and laudable, they are also futile. They have an insignificant impact on the total problem and create another – what to do with the collected plastic?

What Hong Kong needs to do to recycle more: sort waste properly and see it as a chance to make money, not a problem
