The use of plasticulture in agriculture is growing rapidly, perhaps nowhere more visibly than around Almería in southern Spain. The eastern approaches to Almería, north of the airport, are densely covered, as is a large area further northeast, surrounding the towns of Campohermoso, Los Pipaces and Los Grillos (close to Níjar ).
The use of plastic mulch creates a practically weed-free area around the plant, removing the need for cultivation except between the rows of plastic. Root damage associated with cultivation is therefore eliminated. Due to these factors, the use of plastic mulch can lead to an improvement in the overall growth of the plant. [7]
In the early 1970s, the carcinogenicity of vinyl chloride (usually called vinyl chloride monomer or VCM) was linked to cancers in workers in the polyvinyl chloride industry. Specifically workers in polymerization section of a B.F. Goodrich plant near Louisville, Kentucky , were diagnosed with liver angiosarcoma also known as hemangiosarcoma , a ...
Note 2: Biochemists are now capable of synthesizing copies of biopolymers that should be named Synthetic biopolymer to make a distinction with true biopolymers. Note 3: Genetic engineering is now capable of generating non-natural analogues of biopolymers that should be referred to as artificial biopolymers, e.g.,
PVC, used extensively in sewage pipes, is only useful because of plasticizers. [1]A plasticizer (UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture.
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.
The earliest artificial Christmas trees were wooden, tree-shaped pyramids or feather trees, both developed by Germans. Most modern trees are made of polyvinyl chloride (PVC) but many other types of trees have been and are available, including aluminum Christmas trees and fiber-optic illuminated Christmas trees.
