- Are Leetha bio-cups Recyclable?
Yes, Leetha Bio Cups are 100% recyclable, it can be directly fed into a pulper and can be used to make recycled paper.
- Can ordinary LDPE coated paper cups also be recycled?
Specialized machinery are required to separate LDPE film from cup paper unfortunately there very few of these in the world and almost 90% of used paper cups end up in land fill and are not recycled and that means LDPE cups cannot be recycled by most paper mills.
- Are Leetha cups bio degradable?
Yes, Leetha cups are bio degradable, As per ASTM D 5511and as per ASTM 6400 Standard test conducted on the cups by Intertek. Leetha Bio cups are compostable in an industrial composter and even in home compost .and that means it will eaten up aerobic bacteria and anaerobic bacteria Certificates and Test study are available and could be sent on request.
- So does that mean you can throw Leetha bio cup in your back yard and degrades naturally?
- How can I check if leetha bio cups are compostable in natural weather conditions?
Just bury it in your backyard or in your flower pot or where ever you have wet soil and check after 30 days. You will not find any residue .as per international standards a product is termed as biodegradable if it degrades up to 90 % in 6 months' time
- How can I check if Leetha bio cups are recyclable at home and that ordinary plastic cups are not?
Just immerse it in water for 72 hours and you could peel of the LDPE lining from the inner wall of the cup where as the Leetha bio cups we will not get any such films or you could put the cup in any acid PLASTICS DON’T DISSOLVE IN ACID.
For ACID testing methods please check the link below.
- Are Leetha Bio cups food safe and are there any certificates to prove the same?
Yes Leetha bio cups are food safe and migration test conducted by internationally accreditation agencies certifies the same.
OK! Leetha has the certificates , but do have any visual proofs of cups biodegrading in natural weather conditions.

- Are Leetha Bio cups microwavable and are there any certificates to prove the same?
Yes Leetha bio cups are microwavable safe and migration test conducted by internationally accreditation agencies certifies the same.
- Till what temperatures can Leetha bio cups withstand?
It can withstand up to 100 degree centigrade (coffee is generally served at 70 degrees)
- Does the Cup require a Composting facility? Does it have to be Industrial Composting or Home Composting?
Yes, It is home compostable and doesn't require an industrial composting facility. And Yes, these cups gets fully bio degradable in an open landfill Let me just make it a little more elaborate These cups are subjected to tests as per ASTM D 5511 by Intertek ASTM D 5511 is testing process done with AEROBIC BACTERIA . (Aerobic bacteria are bacterias that uses oxygen as an electron acceptor to break down organic compound ) Our cups biodegradation level was 74.8% on the 28th day and 94.01% on the 52nd day Aerobic bacteria are the bacteria that is generally active in a home compost.
- On how does it perform in an industrial composter?
It was also subjected to Anaerobic bacteria testing (Anaerobic bacteria are bacteria that does not use oxygen as an electron acceptor to break down organic compounds ) it generally uses nitrates iron sulphate etc. Our cups biodegradation level for anaerobic biodegradation (without oxygen) was 91.85 % on the 75th day.
- Are Industrial composting facilities really a solution to the plastic menace?
The amount of energy required to run the industrial composting facility and the amount of foot print generated during bio-degrading process in an industrial composter is actually more than the energy required to manufacture LDPE coated paper and that means running an industrial composer is harmful to nature and recycling or natural biodegradation is the ideal solution.
- How thick is this coating ?
The coating thickness is just under 2 grams per square meter
- How thick is Plastic film (LPDE)?
Plastic film is usually laminated in 15 Grams to 20 grams per square meter
- Why is so special about this dispersion coating that makes it Bio-degradable ?
LDPE (plastic film) is made of complicated molecules , their molecular length and molecular weight is very high . Our dispersion coating molecule has very low molecular length and weight which makes it easier for microbes to feed on.
This is similar to Natural Rubber molecules (polyisoprene C5-H8) which is naturally degradable .
