Comprehensive studies focusing on mixed municipal solid waste (MSW) have identified a preferred pathway for maximizing resource efficiency and minimizing environmental impact, including effective waste administration and management, source separation of waste materials, efficient collection systems, reuse and recycling of non-organic fractions ...
The pollution haven hypothesis posits that, when large industrialized nations seek to set up factories or offices abroad, they will often look for the cheapest option in terms of resources and labor that offers the land and material access they require. [1] However, this often comes at the cost of environmentally unsound practices.
Material efficiency is a description or metric ((Mp) (the ratio of material used to the supplied material)) which refers to decreasing the amount of a particular material needed to produce a specific product. [1] Making a usable item out of thinner stock than a prior version increases the material efficiency of the manufacturing process.
Economic returns – more efficient use of products means reduced costs of purchasing new materials, improving the financial performance of a company. Public image – the environmental profile of a company is an important part of its overall reputation and waste minimisation reflects a proactive movement towards environmental protection .
The history of environmental pollution traces human-dominated ecological systems from the earliest civilizations to the present day. [1] This history is characterized by the increased regional success of a particular society , followed by crises that were either resolved, producing sustainability , or not, leading to decline.
Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources. [155] Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant, or an oil spill. Non-point sources are more diffuse.
In 2005 the EU reported total waste of 9 million tonnes and in 2020 estimates waste of 12 million tonnes. This electronic waste with hazardous materials if not managed properly, may end up badly affecting our environment and causing fatal health issues. Disposing of these materials requires a lot of manpower and properly managed facilities.
