grunnhráefni

Grunnhráefni are natural resources that serve as inputs to the production of goods and services. They are extracted or harvested and then processed into materials, fuels, and energy carriers used throughout industry, construction, and agriculture. The term covers a broad set of resources, including minerals and rocks as well as biomass resources and energy resources.

Common categories include industrial minerals and metals: construction materials such as sand, gravel, crushed stone, limestone, and gypsum; metallic ores such as iron ore, copper, and other base metals. Energy resources include petroleum products, natural gas, coal, and biomass-based fuels. In some contexts, peat may also be used as a fuel. Renewable resource flows such as water and timber are sometimes considered grunnhráefni when used as inputs in processing or manufacturing.

Extraction and processing involve exploration, mining or harvesting, beneficiation, refining, and transport to factories and markets. The availability and price of grunnhráefni are influenced by geology, exploration success, geopolitical factors, exchange rates, and demand cycles.

Environmental and social aspects are central to modern management: mining and extraction can affect land and water, ecosystems, and local communities. Policies aim to improve sustainability through responsible sourcing, environmental protection, recycling, material efficiency, and substitution with alternative materials where possible.
