Drinking straws made of PLA-blend bio-flex Jar made of PLA-blend bio-flex, a bioplastic Bio potato lab environmental impact of bioplastics is often debated, as there are many different metrics for "greenness" e. The production and use of bioplastics is sometimes regarded as a more sustainable activity when compared with plastic production from petroleum petroplasticbecause it requires less fossil fuel for its production and also introduces fewer, net-new greenhouse emissions if it biodegrades.
The use of bioplastics can also result in less hazardous waste than oil-derived plastics, which remain solid for hundreds of years. Petroleum is often still used as a source of materials and energy in the production of bioplastic.
Petroleum is required to power farm machinery, to irrigate crops, to produce fertilisers and pesticides, to transport crops and crop products to processing plants, to process raw materials, and ultimately to produce the bioplastic. However, it is possible to produce bioplastic using renewable energy sources and avoid the use of petroleum.
Environmental data from NatureWorks, the only commercial manufacturer of PLA polylactic acid bioplastic, says that making its plastic material delivers a fossil fuel saving of between 25 and 68 per cent compared with polyethylene, in part due to its purchasing of renewable energy certificates for its manufacturing plant.
A detailed Bio potato lab examining the process of manufacturing a number of common packaging items from traditional plastics and polylactic acid carried out by Franklin Associates and published by the Athena Institute shows that using bioplastic has a lower environmental impact for some products, and a higher environmental impact for others.
While production of most bioplastics results in reduced carbon dioxide emissions compared to traditional alternatives, there is concern that the creation of a global bioeconomy required to produce bioplastic in large quantities could contribute to an accelerated rate of deforestation and soil erosion, and could adversely affect water supplies.
Careful management of a global bioeconomy would be required. In the study, the production of corn-based plastics created more acidificationcarcinogensecotoxicityeutrophication, ozone depletion, respiratory effects and smog than the synthetic-based plastics they replaced.
The American Carbon Registry has also released reports of nitrous oxide caused from corn growing which is times more potent as a greenhouse gas than CO2. Pesticides are also used in growing corn-based plastic. Biodegradable plastic Packaging air pillow made of PLA-blend bio-flex The terminology used in the bioplastics sector is sometimes misleading.
Most in the industry use the term bioplastic to mean a plastic produced from a biological source. All bio- and petroleum-based plastics are technically biodegradablemeaning they can be degraded by microbes under suitable conditions. However, many degrade so slowly that they are considered non-biodegradable.
Some petrochemical-based plastics are considered biodegradable, and may be used as an additive to improve the performance of commercial bioplastics. The biodegradability of bioplastics depends on temperature, polymer stability, and available oxygen content.
This standard is recognized in many countries, including all of Europe, Japan and the US. However, it applies only to industrial composting units and does not set out a standard for home composting. PH only biodegrade quickly in industrial composting units.
Starch-based bioplastics are an exception, and will biodegrade in normal composting conditions. To prevent this, process manufacturers add stabilising chemicals. This type of plastic may be referred to as degradable plastic or oxy-degradable plastic or photodegradable plastic because the process is not initiated by microbial action.
While some degradable plastics manufacturers argue that degraded plastic residue will be attacked by microbes, these degradable materials do not meet the requirements of the EN commercial composting standard.
The bioplastics industry has widely criticized oxo-biodegradable plastics, which the industry association says do not meet its requirements.

Summary The resources that animals mainly compete for are food, water, space to live and breed in (including access to food and water), and for access to mates.
