Recycling paper decreases the demand for virgin pulp and thus reduces the overall amount of air and water pollution associated with paper manufacture. Recycled pulp can be bleached with the same chemicals used to bleach virgin pulp, but hydrogen peroxide and sodium hydrosulfite are the most common bleaching agents. Recycled pulp, or paper made ...
The type of packaging materials including glass, aluminum, steel, paper, cardboard, plastic, wood, and other miscellaneous packaging. [5] Packaging waste is a dominant contributor in today's world and responsible for half of the waste in the globe. [4] The recycling rate in 2015 for containers and packaging was 53 percent.
Bufferbloat is the undesirable latency that comes from a router or other network equipment buffering too many data packets. Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput .
Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane , with the remainder being mostly carbon dioxide .
Plastic pollution, specifically microplastics, are a major contributor of PCBs into the biosphere and especially into marine environments. PCBs concentrate in marine environments because freshwater systems, like rivers, act as a bridge for plastic pollution to be transported from terrestrial environments into marine environments. [ 45 ]
Acidic paper is paper which was manufactured using acidic substances. [1] Widely used since the mid-nineteenth century, its pages become yellow within years, extremely brittle over decades, and eventually unreadable in the library and archive collections intended to preserve them. [2] This process has been called "slow fire".
Visual pollution is a major effect of litter. Open containers such as paper cups, cardboard food packets, plastic drink bottles and aluminum drinks cans get filled up with rainwater, providing breeding locations for mosquitoes. In addition, a spark or a lightning flash can start a fire if it strikes litter such as a paper bag or cardboard box.
Plastic coatings or layers usually make paper recycling more difficult. Some plastic laminations can be separated from the paper during the recycling process, allowing filtering out the film. [10] [11] If the coated paper is shredded prior to recycling, the degree of separation depends on the particular process. Some plastic coatings are water ...
