The cost of disposing of paper in the workplace can not be ignored. Costs of supplies such as toner and paper and equipment repairs will increase rapidly. Perhaps more important than these costs is trying to arrange printers and copiers, filing documents, and then rediscovering them often wasting employees' time to discard them. Using less paper can save your organization money and help with many environmental issues. 42% of all trees harvested for industrial purposes go to paper production. Unfortunately, deforestation is only one part of the story. The pulp and paper industry is the largest industrial consumer of water, the largest water pollutant, and the third largest emitter of global warming pollution in most industrialized countries.
Plastic waste mainly enters the environment when it is poorly managed, i.e. open waste, open incineration and disposal in waterways. Unfortunately, plastic waste is on the rise as a quarter of the waste is dumped in public and many formal disposal sites are improperly managed. There are many ways to prevent plastic waste produce less, consume less, and better manage existing waste to prevent contamination or leakage. Taking these steps requires the involvement of many stakeholders in the community, including citizens, governments, community organizations, businesses, and manufacturers. Policy solutions, increased awareness, improved design and processing processes, among others, can reduce the impact of plastic waste on society.
Used metals are a major source of scrap metal, industrial metals and alloys, especially in the production of steel, copper, lead, aluminum and zinc. Small amounts of tin, nickel, magnesium and precious metals are also recovered from the scrap. Waste containing organic matter such as wood, plastic, paint and textiles can be incinerated. Metal impurities can be desirable, inactive, or undesirable. Undesirable ones may be mixed with pure metal in tolerable proportions, or they may be cleaned and removed. Scrap is usually mixed and re-melted to form alloys similar to or more complex than those derived from scrap.
