The issue of waste
New Zealand generates almost 3.2 million tonnes of waste that is buried in landfill sites. Waste disposed of in this way is an inefficient use of resources, as much of the waste could have been separated and reused, recycled or turned into compost.

Modern landfill systems
The way we dispose of wastes in New Zealand has changed dramatically over the last few decades. We have moved from literal dumps and tips to complex landfill systems. The following activities cover engineering practices, a timeline of rubbish disposal, waste management and minimisation in our local environments.

Biodegradability, recycling and reuse
A biodegradable object is one that will break down quickly and safely into harmless compounds by using the action of microorganisms. Composting is another name for biodegrading.

When you can make plastics that have an environmental benefit or don’t use fossil fuels, that gives me an extra drive and a passion to develop an end product.
