Traitement des eaux usées industriellesLe traitement des eaux usées industrielles décrit les procédés utilisés pour traiter les eaux usées produites par les industries en tant que sous-produits indésirables. Après traitement, les eaux usées industrielles (ou effluents) traitées peuvent être réutilisées ou rejetées dans un égout sanitaire ou une eau de surface dans l'environnement. La plupart des industries produisent des eaux usées. Les tendances récentes ont été de minimiser une telle production ou de recycler les eaux usées traitées dans le processus de production.
Radiant heating and coolingRadiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels", "embedded surface systems", "thermally active building systems", and infrared heaters.
Resource warA resource war is a type of war caused by conflict over resources. In a resource war, there is typically a nation or group that controls the resource and an aggressor that wishes to seize control over said resource. This power dynamic between nations has been a significant underlying factor in conflicts since the late 19th century. Following the rise of industrialization, the amount of raw materials an industrialized nation uses to sustain its activities is heightened.
Natural resource economicsNatural resource economics deals with the supply, demand, and allocation of the Earth's natural resources. One main objective of natural resource economics is to better understand the role of natural resources in the economy in order to develop more sustainable methods of managing those resources to ensure their availability for future generations. Resource economists study interactions between economic and natural systems, with the goal of developing a sustainable and efficient economy.
