frequently asked questions

How do Biodegradable Future additives work?
Our additives accelerate the biodegradation process of plastic in microbe-rich environments, such as soil, oceans and landfills. The additive attracts microbes to the plastic product and lets them control the PH level and become quorum sensing and colonise the plastic surface. Through colonisation, the polymer chain breaks down and this gets used as a source of energy for the microbes.

How much additive is necessary?
The amount of additive required varies depending on product characteristics i.e. thickness, size of product, desired speed of biodegradation.

Do additive treated products have a limited shelf-life?
No, treating your plastic with our additives will not shorten the product’s shelf-life.

Are you FDA compliant?

Will the additive change the physical integrity and structure of the plastic?
No, there will be no noticeable changes to the plastic, meaning you will not need to compromise to make the change.

Is the additive suitable for all kinds of plastics?
The additive can be used with any petroleum-based resin.

How can you be sure that plastic treated with additives will completely biodegrade?
ASTM D 5511 tests are underway with promising results.

What tests have been performed on treated products? 

These tests have been performed on treated bottles to verify recyclability. These are standard tests used to determine the quality of PET plastic regrind.
Haze and Transmission via ASTM D 1003B
Intrinsic Viscosity via ASTM D 4603
Acetaldehyde via ASTM F 2013
Fluorescence Visual Visual Black Specks and Gel.

Will treated plastic biodegrade in marine environments as well?
Treated plastic will biodegrade in any active microbial environment, including lakes, oceans and streams. Through testing, we can confirm that treated products biodegrade in both aerobic and anaerobic environments.

What are the ASTM standardized testing methods for biodegradation?
D6400 Standard Specification for Compostable Plastics
D5338 Standard Test Method for Determining Aerobic Biodegradation of Plastic Materials Under Controlled Composting Conditions
D5511 Standard Test Method for Determining Anaerobic Biodegradation of Plastic Materials Under High-Solids Anaerobic Digestion Conditions

What are the stages of biodegradation in a landfill environment?
1. Aerobic Phase (first few days)
2. Anaerobic, Non-Methanogenic Phase (roughly 2 weeks to 6 months)
3. Anaerobic, Methanogenic Unsteady Phase (6 to 18 months)
4. Anaerobic, Methanogenic Steady Phase (1 year to 5 years)

Do polymers stay in the soil after biodegradation?
No, the microbes use the carbon for energy and leave nothing of the polymer behind when the process of digestion is complete.

Letdown Ratio:
The minimum let down ratio for additive – 0% 67 is 0.5 lbs of masterbatch per 100 lbs of resin. The level of additive – 0% 67 used in the customers final product may have to be adjusted to facilitate meeting ASTM Biodegradation Tests such as ASTM, D5511, D5338, D6400, etc.

This material is considered to be thermally stable in the normal and customary processing range of 360º – 400º F. Extended polymer and concentrate residence time in the process equipment may require that process temperature profiles be reviewed and/or adjusted to insure a proper and suitable product.

Regulatory Information:
The additive – 0%67 is made only from FDA recognised materials and processes regulated according to 21CFR 175.300, 177.1200, 177.1350 and other sections.

Storage Information: 
We recommend that inventories are rotated and used within 6 months of purchase for optimum performance. If less than a full, sealed package is used in one session, the package should be resealed before storage.

Safety Information:
Our additive – 0% 67 is not known to contain hazardous materials as outlined by current OSHA regulations. Please refer to the MSDS for additional safety information.

Packaging Information:
Our additive – 0%67 is typically packaged in 55 lb bags

* Biodegradation rates of Bio Future's additives -treated plastic materials measured according to the ASTM D5511 test method. Tests are generally conducted using 20% to 30% solids content; solids content in naturally wetter landfills range from 55% to 65%, while the driest landfills may reach 93%. Actual biodegradation rates will vary in biologically-active landfills according to the type of plastic used, the product configuration, and the solid content, temperature and moisture levels of the landfill.
