Impact on sustainability
Greater consideration is now given to ensuring that the materials and energy we use are sustainableA sustainable resource can be replaced once used. As a tree is chopped down, many more can be planted to ensure the use of trees can be sustained. . This includes where the resources come from and how they are disposed of at the end of their life.
Finite resources
finite resourceResource that can only be used once and is in limited supply. For example, oil is a finite resource. are non-renewableA resource that cannot be replaced when it is used up, such as oil, natural gas or coal. and will eventually run out. Metals, plastics and fossil fuelNatural, finite fuel formed from the remains of living organisms, eg oil, coal and natural gas. (coal, natural gas and oil) are all examples of finite resources. Finite resources are popular as they are easily accessible due to strong supply chains and often have benefits for manufacturing particular products or for energy supplies. Companies have become more careful in their use of finite resources, and they now consider the ecological footprintAn analytical measurement of the amount of global resources used. caused by using such materials.
Non-finite resources
non-finite resourceA renewable energy that harnesses the Earth's natural resources. are found naturally and can be replaced. Examples include wood, cotton and renewable energyPower that is generated using natural resources that will not run out, eg wind and wave power. sources such as solar and wind. Where trees are cut down for wood or hibiscus plants harvestedWhen crops are collected from the fields. for cotton, new ones can be planted in their place.
Waste disposal
How materials and resources are disposed of is carefully monitored and managed by local councils. Households are encouraged to recycle waste items where possible, including products made from various materials such as hard plastics, paper and steel. Natural garden waste can also be recycled. In 2016, the UK recycled 25 per cent of household waste, with the target of 50 per cent in 2020. All other waste goes to landfill sitesPlaces where refuse is buried underground., which release harmful gases that pollute the surrounding air and soil.
