Why are repurpose compostables a sustainable product?
repurpose compostables are made from annually renewable resources. repurpose compostables are currently produced from the annually renewable resource corn (maize), the lowest cost and most widely available fermentable sugar in the world. repurpose compostables is working with suppliers to develop new conversion technologies to facilitate the use of lignocellulosic biomass feedstocks, such as corn stover (the residue left in the field), grasses, wheat and rice straws, and bagasse (the residue of sugar cane production).
To produce repurpose compostables, fewer fossil resources are required. The conventional hydrocarbon polymers use limited reserves of oil and natural gas as their feedstock source. Fossil fuels take millions of years to regenerate.
repurpose compostables fits into any waste management system with a benefit. At the end of their useful life, repurpose compostables can be disposed of by all traditional waste management methods such landfill, however repurpose products are best disposed of when they can be composted in industrial composting facilities.
What is PLA?
PLA stands for polylactic acid, or Polylactide, a versatile polymer. PLA is made from lactic acid. Lactic acid is made from dextrose by fermentation. Dextrose is made from starch and starch is made from carbon dioxide and water.
PLA is the world's first and only performance plastic made from 100% annually renewable resources. Corn-based PLA offers the cost and performance necessary to compete with traditional petroleum-based materials in the packaging and serviceware markets.
Does repurpose compostables require GMO corn?
No, special crops or modifications are not required to produce repurpose compostables. During the manufacture of PLA, the multiple-stage processing and high heat used to create the polymer removes all traces of genetic material. repurpose compostables also undergo NON-GMO Certification processes.
I understand that repurpose compostables does not contain GMO but does it promote the prevalence of GMO into the world?
No, since special feed corn varieties are not required to produce PLA, repurpose compostables does not promote the proliferation of any specific agricultural practices.
Do repurpose compostables degrade during usage?
No, repurpose compostables are similar to other natural structures used for packaging, such as paper, which maintains product integrity during use.
Will repurpose compostables degrade on store shelves?
repurpose compostables will not degrade on retail shelves. repurpose compostables are similar to other natural structures used for packaging, such as paper, which maintains product integrity during use.
Does repurpose compostables offer better disposal options than traditional petroleum-based plastics?
Yes, repurpose compostables have the flexibility to be disposed of in several manners and fits most local end-of-life schemes throughout the world. These multiple disposal alternatives mean it can play a key role in landfill diversion. repurpose compostables have been successfully composted in applications where a commercial composting infrastructure is in place
Can I throw repurpose compostables into my backyard compost?
repurpose compostables should be composted in industrial compost facilities, which contain the right managed combination of temperature and moisture. Therefore, it is not recommended for use in typical backyard composting due to the lack of high temperature and inconsistent conditions.
repurpose compostables are designated as compostable in the United States, as opposed to biodegradable in other geographies. What is the difference?
In the United States, the Federal Trade Commission publishes a "Green Guide." According to Green Guide, repurpose compostables falls under the category of "compostable." The Green Guide defines compostable products as those that will break down, or become part of usable compost, in a timely matter. For composting, a "timely manner" is approximately the same time that it takes organic compounds, like leaves, grass and foodstuff to compost. Biodegradable materials are defined as those which break down and return to nature in a reasonably short amount of time after customary disposal or use. A "reasonably short time" depends on where the product is disposed. For specifics on the FTC's Green Guide, visit: http://www.ftc.gov/bcp/grnrule/guides980427.htm#260.7.
Do repurpose compostables use more energy and hence emit more greenhouse gases than the manufacturing of other traditional petroleum-based plastics?
Peer-reviewed and published life-cycle analysis (LCA) data show that polyactic acid (PLA) requires fewer fossil resources and generates fewer greenhouse gases than traditional plastics.
I heard PLA will melt in extreme heat, is this true?
Like most clear or transparent polymer, exposure to high temperatures and humidity can adversely affect the performance and appearance of plastic materials depending on the use. It is recommended that repurpose compostables be stored at temperatures less than 105ºF (40ºC)
