*Time requirement for degradation depends on the environment in which the materials are disposed, as types, quantity and quality of micro-organisms.

Plastics manufactured using ENSO additives are biodegradable in anaerobic (no oxygen, no light), aerobic  environments and can be comingled with standard plastics during recycling.  The technology behind ENSO additive allows our products to be metabolized and neutralized in the environment, turning them into inert humus (biomass), biogas (anaerobic) or Co2 (aerobic). 

The development of our bottles marks a turning point from traditional plastics to a more earth friendly plastic and provides a turn-key stable solution over starch-based and other products currently on the market today.

Products made using ENSO additive maintain the same physical properties and strength as traditional plastics.  If you have a color feeder, no additional manufacturing equipment is needed for processing ENSO additive.  Once manufactured, your products have an indefinite shelf life and are not affected by light, heat, moisture or stress.  These attributes will last until the product is discarded into an active microbial environment (landfill), and will then break down into inert humus (biomass), Co2 or biogas.

Is the ENSO permeation rate the same as Standard plastics?

Yes, products made using ENSO additive retain the same permeation rate as traditional plastics.

Can bottles made with ENSO be used for hot fill and carbonated beverages?

Yes, bottles made using ENSO additive can be used for hot fill and carbonated beverages. There is no increased heat sensitivity or permeation when compared to traditional PET.

Can customers use the regrind containing ENSO?

Yes, however it is recommended to implement quality control to ensure the approved amount of material is being loaded into the resin.

Note: PLA users are unable to use PLA regrind and must send any waste back to NatureWorks for processing and credit towards future orders. Oxo-degradable user can use oxo-degradable regrind.

Can yellow dye and other colorants be used with ENSO plastics?

Yes, there are no issues with using any colorants with ENSO.  The ENSO additive may have an effect on the final color and adjustments should be made to ensure accurate final color.

It is recommended that you use an organic, linseed or a non UV powdered base colorant.  This is recommended to prevent potential residue after biodegradation caused by the ink.

Note: PLA requires linseed colorant use only due to all products being required to be disposed of in professional composting facilities.

What is the manufacturing process for using ENSO additive?

Using additive in the manufacturing process is very easy to do.  The ENSO additive is added via a standard commercial dry feeder just as you would add a colorant into the throat.  It is loaded at 1% by load weight, the remaining process parameters should stay virtually the same.

Are there any special handling requirements of the ENSO additive?

Yes, always make sure to seal the unused portion of additive because it could be slightly hygroscopic.  It is also a good idea to rotate the lot every six months to ensure good quality control.

Also do not run the additive at over 600F as this has not been tested and the results cannot be guaranteed.

Does the ENSO additive impart any taste to the product contained in it?

No, there is no known taste, flavor or smell imparted to ENSO bottles.

Plastic has been around for a long time, why hasn't one of the big plastic manufacturers already offered this product?

There were significant technological advances which were required to take place in order to create a product that was compatible with the high pressure and temperature demands of today’s plastic processing. With the combined expertise of our partners we were able to overcome this hurdle and produce biodegradable product without sacrificing the package integrity or clarity.

How do you know ENSO bottles with the ENSO additive are safe?

ENSO only uses materials that are FDA compliant for food contact.

How does the ENSO additive change the physical characteristics of the traditional plastic

There are no noticeable changes to the plastic physical characteristics such as tensile strength, glass temperature, melting temp, transition rates, etc. Some of these values are identified in the TDS (Technical Data Sheet). The ENSO material does create a light haze in clear products. We encourage customers to perform specific tests to validate any properties they may be concerned with.

Do products made with ENSO decrease in performance when operating at elevated temperatures?

No. Tensile strength and the physical properties are maintained even in elevated temperatures. Temperatures that exceed the plastics normal operating range would experience the same loss of properties as without ENSO.
