recycling also helps with the emissions produced by the waste itself. That’s because items that are sent to landfill leach harmful gases into the atmosphere over time, while those burned in an incinerator – even when the residual energy created during the process is...
recyclingmetalIn countries with limited exhaustible natural resources, reducing imports of raw materials is increasingly viewed as a significant side benefit of waste recycling. Using a panel of 21 developed and developing countries from 1994-2008, we seek to measure the size of this benefit by ...

In those cases, the recycling process probably takes more energy. It can also be difficult to weigh all the energy costs along the entire chain of production. Recycling steel certainly uses less energy than the entire process of mining iron ore, refining it and forging new steel. Some contend...
How does climate change affect ecosystems? How does feedstock recycling work? How does the Milankovitch cycle affect climate change? How do politics affect climate change? How does renewable energy reduce climate change? How did the ice age affect the environment?
We found that in 2018, the potential phosphorus supply from recycling technologies was on average 0.38, 0.29 and 0.05 kg of phosphorus per capita for Danish, German, and Spanish regions. These quantities could meet 9.1, 21.7, and 10.0 percent of the phosphorus required to produce major cereals...
the demand for energy has been growing. If this is not contained, then the world’s energy consumption will keep on increasing. The ever-growing need for energy makes it difficult to make the transition towards renewable sources and reduce fossil fuel consumption that leads to greenhouse gas emi...
This means the lamp can produce more light than it would otherwise do and also helps to reduce flicker. The circuit is connected to a couple of electrical contacts called electrodes. When electricity flows into the electrodes, electrons (shown here as red dots) boil" from their surface and ...
The international community must act immediately to ensure that all countries reduce the consumption of fossil fuels (e.g. gas and oil). To what extent do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or experience. Write at leas...
Your renewable energy usage The sustainability of your products’ materials The recycling of your packaging 2. Supplier collaboration The next step is to work closely with your suppliers to address these issues. For example, your products’ manufacturer(s) may be able to suggest ...
