Reuse, recycle, repurpose is what we need to do when it comes to processing end of life materials. In this episode of ‘Finding Out’ Dr Hines explains the need to reuse, recycle and repurpose waste materials. Finding Out is the podcast for the curious. If you want to know what waste is, how it is measured, processed and what you can do to contribute to reducing your carbon footprint this episode will provide some answers. Waste material is costly. When we dispose of waste we are effectively throwing away resources that once we thought useful. There are different types of waste. A primary distinction is between household and industrial sources. Re-use, recycle, repurpose is what we need to do when it comes to processing end of life materials. Recycling is important to all our lives. Once waste is produced we need to manage it. There are different types of waste from two main sources: Households and Industry. There are different types of waste categories: solid, liquid, recyclable and non-recyclable. All types in the waste flow need to be managed. Recycling is important to the ‘Circular Economy’. It brings waste back in through re-use, recycling and repurposing it. In doing so it lowers carbon use and reduces other greenhouse gases. In the US the Environment Protection Agency are responsible for gathering data, producing statistics and managing waste. The EPA has gathered waste data for the past 35 years. In the UK the Department for Environment,Food and Rural Affairs is responsible for waste. Forty per cent of all waste comes from construction materials in both the US and UK. Food is the second largest waste product. Listen to the episode to find out more.

The International Panel on Climate Change (IPCC) gave a stark warning that temperatures are rising across the world. The IPCC estimated that if no further action to reduce CO2 was taken temperatures would increase by 1.5 degrees centigrade within 11.5 years. It is regarded by may as the point of no return. Ice caps melt, sea levels rise, the planet gets warmer because of increasing CO2 and other greenhouse gases. This impacts all our lives. In this episode of Finding Out we look at the ways in which we heat our homes. In the United Kingdom 23 million homes rely on Natural Gas which produces CO2 as a byproduct. Two main alternatives have been considered to reduce CO2. The first is using a heat pump to push natural heat captured from the environment around the home. The second is to use Hydrogen as the energy source which produces only water as a byproduct and is far less harmful than Natural Gas. However, both proposed alternatives incur greater capital cost to install into existing homes.
