Petroleum plastic

One of the main barriers to the widespread use of biodegradable plastics is their higher production cost compared to petroleum plastics. For example, whereas the cost of most commodity plastics, such as polypropylene, is well below 1 US /kg, the costs of some of the cheapest biodegradable plastics on the...

The Karl Fischer method is applied in a multitude of substances from finished products (butter, cheese, dried milk sugar, etc.) to solvents and other industrial products (paper, gas, petroleum, plastic films, etc.). Solids and not soluble samples must, prior to the measurement, either be ground into powders, extracted with anhydrous solvents, eliminated as azeotropes or heated to evaporate the water in special accessories. The only difficult cases are encountered with strongly acidic or basic media since they denature reactants as well as ketones and aldehydes which perturb the titration through formation of acetals (special reagents must be used for these instances). 

One of the most important examples of heterogeneous catalysis is the addition of H2 to the C=C bonds of organic compounds to form C—C bonds. The petroleum, plastics, and food industries frequently use catalytic hydrogenation. The conversion of vegetable oil into margarine is one example. 

To develop PHA into a commercially acceptable material, following efforts have to be made first, feasible technology must be developed to reduce PHA production cost to a level competitive to petroleum plastics secondly, value-added functionalities must be provided to PHA so that high production cost can be compensated by its high-end-applications. 

The PHA produced in the above way have a cost similar to petroleum plastics, allowing PHA to compete with conventional plastics not only with its environmentally friendly features but also with its low cost and sustainability. By then PHA will have a significant share of the big pie belonging to conventional packaging materials. 

Bioplastics today can be made from corn, soy, sugarcane, potato, or other renewable material source. Petroleum plastics can also be sustainable if they are made from renewable or recycled material sources. The manufacturing process also can also be sustainable. Plastics have the opportunity to define sustainable materials that are made from renewable or recycled materials sources, made with lower energy, produce less pollution, and have a low carbon footprint. Sustainable plastic materials also are recycled or composted at the end of the product service life.
