Frequently Asked Questions
Eight percent of the world’s current oil production is used to produce plastics, and these plastics, after use, take up at least 25 percent of an average landfill site. Reducing and redirecting materials from landfills is a major goal of environmental reform. Our products are made from renewable resources with minimal long-term environmental impact so as to preserve our natural resources for future generations.
Compost enriches soils--
Compost has the ability to help regenerate poor soils. The composting process encourages the production of beneficial micro-organisms (mainly bacteria and fungi) which in turn break down organic matter to create humus. Humus--a rich nutrient-filled material--increases the nutrient content in soils and helps soils retain moisture. Compost has also been shown to suppress plant diseases and pests, reduce or eliminate the need for chemical fertilizers, and promote higher yields of agricultural crops.
Compost helps cleanup (remediate) contaminated soil--
The composting process has been shown to absorb odors and treat semivolatile and volatile organic compounds (VOCs), including heating fuels, polyaromatic hydrocarbons (PAHs), and explosives. It has also been shown to bind heavy metals and prevent them from migrating to water resources or being absorbed by plants. The compost process degrades and, in some cases, completely eliminates wood preservatives, pesticides, and both chlorinated and nonchlorinated hydrocarbons in contaminated soils.
Compost helps prevent pollution--
Composting organic materials that have been diverted from landfills ultimately avoids the production of methane and leachate formulation in the landfills. Compost has the ability to prevent pollutants in stormwater runoff from reaching surface water resources. Compost has also been shown to prevent erosion and silting on embankments parallel to creeks, lakes, and rivers, and prevents erosion and turf loss on roadsides, hillsides, playing fields, and golf courses.
Using compost offers economic benefits--
Using compost can reduce the need for water, fertilizers, and pesticides. It serves as a marketable commodity and is a low-cost alternative to standard landfill cover and artificial soil amendments.
Composting also extends municipal landfill life by diverting organic materials from landfills and provides a less costly alternative to conventional methods of remediating (cleaning) contaminated soil.

For a commercial or corporate user of compostable materials, your “tipping cost” to have these products taken to a compost facility are less than the cost to have your trash taken to a landfill. In addition, many companies are able to purchase back humus soil from the composter at a reduced cost. The savings are greater if a commercial or corporate user has the willingness and ability to compost their own waste and eliminate the tipping costs and generate their own compost for landscaping soil enrichment. Individual consumers save money by buying in bulk at costs lower than grocery store or discount store pricing, without having to travel to the store. In addition, composting at home can reduce your trash hauling costs and generate your own rich soil humus for gardening and landscaping. Start your own garden…$30 worth of vegetable seedling plants can generate over $100 worth of food. Starting from seed can save even more. According to Burpee, the world’s largest seed producer, $20 worth of seeds can generate $650 worth of vegetables.
Biolice is the only non-food brand of Limagrain. The biolice products are bioplastic compounds made from flour of cereals, mainly maize. Ten years of patient work have been dedicated to developing, naturally, the cereal varieties used to make biolice. All our cereals are grown in the black soil of the Auvergne by our farmer members. They are certified non-GM. The extrusion process by dry is unique on the market. It helps to minimize the environmental impacts during manufacture. All products in the range are 100% biodegradable and 100% compostable. They comply with EN 13432 and receive labels OK Compost and Din Certco.
Biolice brand aims at processors of plastics: extruders, thermoformers, assemblers ... Biolice products enable the implementation of flexible products: mulch film, bags, industrial films, netting or rigid products: horticultural pots, cotton buds, trays ...
ASTM defines “Compostable” as capable of undergoing biological decomposition in a compost site as part of an available program, such that plastic is not visually distinguishable and breaks down to carbon dioxide, water, inorganic compounds, and biomass, at a rate consistent with known compostable materials (e.g. cellulose).
ASTM defines “Biodegradable” as capable of undergoing decomposition into carbon dioxide, methane, water, inorganic compounds or biomass in which the predominant mechanism is the enzymatic action of microorganisms that can be measured by standardized tests, in a specified period of time, reflecting available disposal condition.
Oxo-Biodegradable Plastics contain a catalyst which speeds the decomposition of long molecular chains into shorter molecular chains which then can be consumed by microorganisms in a biodegradation process. Often these catalysts are salts of transition metals such as cobalt. They rely on exposure to heat above 140° F or sunlight (UV) to begin the oxidation process. Once the oxidation process starts, it cannot be stopped. Anaerobic refers to microorganisms that are active in the absence of free oxygen. Aerobic refers to microorganisms that are active only in the presence of free oxygen.
Our films can biodegrade in both aerobic and anaerobic environments. However, the most common disposal environment for our products would be in a landfill.
ASTM D5511-02 testing is utilized to show evidence of biodegradability within a 120 day time period under controlled conditions. Biodegradation does not occur in a predictable, straight-line fashion. Rather it occurs in a series of stops and starts as various microorganisms participate in the biodegradation process. This and variability of microorganism type and quantity from landfill to landfill make it impossible to put a firm number on how long it will take to biodegrade. In general, one can safely say cast polypropylene (CPP) film with EcoPure™ should biodegrade in landfills within “years” as opposed to “100’s of years” for CPP without EcoPure™.
We have tested a clear 5 mil CPP film under ASTM D5511-02 conditions. The test was conducted for 90 days and the result was about 30% biodegradation of our film.
Biodegradation percent is calculated per the ASTM D5511-02 method which measures the net gaseous carbon produced from a test vessel minus the net gaseous carbon from a blank vessel only containing innoculum (innoculum is derived from anaerobic digesters operating only on pretreated household waste).
ASTM D5511-02 is a test method that determines the degree and rate of anaerobic biodegradation of plastic materials in a high-solids anaerobic environment. Test materials are placed in an innoculum that is derived from anaerobic digesters operating only on pretreated household waste. Testing is conducted over a specified period of time so no estimates can be made as to when the plastic material will fully biodegrade.
ASTM D6400-04 covers plastics and products made from plastics that are designed to be composted in municipal and industrial aerobic composting facilities. According to the standard, a plastic product must disintegrate during composting so that the remaining plastic material is not distinguishable from other organic materials. For satisfactory disintegration, the plastic material must retain 10% or less than its original dry weight after 12 weeks at test conditions. In addition, 60% of the organic carbon of a single polymer product (like our Super Clear or Tear Seal films) must be converted to carbon dioxide within the 12 week test.
