The plastic materials themselves are often and broadly referred to as "ag plastics". Plasticulture ag plastics include soil fumigation film, irrigation drip tape/tubing, plastic plant packaging cord, nursery pots and bales, but the term is most often used to describe
Biodegradation of any plastic is a process that happens at solid/liquid interface whereby the enzymes in the liquid phase depolymerize the solid phase. [71] Certain types of bioplastics as well as conventional plastics containing additives are able to biodegrade. [72]
A plastic is considered a bioplastic if it was produced partly or wholly with biologically sourced polymers. A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44]
For example, though most of her clothes are made of non-plastic cotton and wool, some of her clothes are made of plastic fibers, like the spandex, polyester, and nylon in her activewear.
The development of plastics has evolved from the use of naturally plastic materials (e.g., gums and shellac) to the use of the chemical modification of those materials (e.g., natural rubber, cellulose, collagen, and milk proteins), and finally to completely synthetic plastics (e.g., bakelite, epoxy, and PVC).
Second, engineering issues. Biodegradable polymers are mostly plant-base materials, which means they originally come from organic source like soybean or corn. These organic plants have the chance to be sprayed with pesticides which contain chemicals which can contaminate the crops and be transferred into the final finished product.
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
Thinking of plants as lives that serve their own purposes opens up a distinct way of understanding our connection to them. They are independent from us and yet knowable; otherworldly and yet familiar.
