| environ. | raw material consumption The developed countries depend on a stable supply of raw materials for their industries. Total resource requirements are increasing rapidly over the entire world. In developed countries, although population is increasing slowly, per capita use is increasing rapidly, while the opposite is happening in developing countries. Traditionally raw materials have been classified as non-renewable resources, but a distinction may be important between "loosable" resources, such as oil and coal, and "non-loosable" resources, such as metals, which can be used several times over by recycling processes | lehengai-kontsumo |

| environ. | recycled material Waste materials that are transformed into new products in such a manner that the original products may lose their identity | material birziklatu |
| environ. | renewable raw material Resources that have a natural rate of availability and yield a continual flow of services which may be consumed in any time period without endangering future consumption possibilities as long as current use does not exceed net renewal during the period under consideration | lehengai berriztagarri |
