Percentage change = (new value - old value) ÷ old value × 100. The Data Analysis and Sustainable Development notes cover this in full.
The three Rs are reduce, reuse and recycle, and the hierarchy matters: reduce first, then reuse, then recycle. The Evaluating Resource Reduction Strategies notes cover this in full.
Aluminium melts at 660°C, much lower than iron at 1538°C. The Recycling in Practice: Glass and Metals notes cover this in full.
A composite material combines two materials with different properties: a matrix that surrounds and binds together fibres or fragments of a reinforcement. The Material Properties and Composites notes cover this in full.
Reverse osmosis is a desalination method that uses high pressure to force water molecules through a semi-permeable membrane, which blocks salt ions. The Water Treatment for Different Sources notes cover this in full.
NPK fertilisers are formulations of salts containing nitrogen, phosphorus and potassium compounds, used to improve plant growth and agricultural productivity. The NPK fertilisers and their importance notes cover this in full.
Potable water is water that is safe to drink, with sufficiently low levels of dissolved salts and microbes. The What is Potable Water and How Do We Make It? notes cover this in full.
Soda-lime glass is made by heating a mixture of sand, sodium carbonate and limestone to approximately 1500°C in a furnace. The Glass and Clay Ceramics notes cover this in full.
