what is it ?
Polyhydroxyalkanoates (PHA) is a group of naturally biodegradable polymers that are made from the nature. More than 150 different monomers can be combined within this group to produce materials with extremely different properties. The mechanical and biocompatibility of PHA can be changed by blending, modifying the surface of combining PHA with other polymers, enzymes and inorganic materials, making it possible for a wider range of applications.
why is it better ?
PHA's are plastic the way nature intended. PHAs provide a tunable property to substitute fossil fuel derived plastics in a wide range of applications. PHAs are both bio-based and biodegradable which means they are both derived from the nature and goes back to nature. Making PHA leaves six times less carbon footprint than that of traditional plastic and another advantage is the transformations of toxic materials by microorganisms during fermentation.
We produce PHBV pellets and we call it LENTILS because as the name suggests, they are tiny, sustainable, high value and nature’s gift to us. LENTILS are 100% biodegradable and customisable which makes it the ideal choice for various applications.
These pellets have been customised for the flexible packaging market as they can be turned into films and sheets.
— Injection moulding
These pellets have been customised for mouldable products like cups, toys, jars, switches, bottles etc.
— 3D Printing
These pellets have been customised to be converted to filament for 3D printing purposes.
— Fibers & Non-woven
These pellets have been customised to undergo melt-spinning to produce sustainable fibers which are alternatives to traditional polyester.
PHAs are humectants, which allows them to attract moisture to the skin, improve hydration and give antioxidant and anti-inflammatory benefits when used as skin exfoliant.
To understand sustainability we need to understand the difference between biodegradable, bio-based, non-biodegradable, fossil-based and recyclable.
Biodegradable simply means that the material can go through a chemical process where microorganisms in the environment convert the material back into natural substances like carbon dioxide, biomass and water.
Biobased refers to where the material comes from, it can be partially or fully biobased. Conventional plastics use non-renewable resources from the earth. Biobased plastics come from renewable biomass, meaning plants.
These kinds of materials are not capable of being broken down by the action of living organisms and end up in our environment for millions of years.
Also known as traditional plastics, these are polymers made from petrochemicals which means they use non-renewable source of energy to get produced.
Unlike popular belief, not all polymers are recyclable. Recycling is just a delayed form of havoc. Less than 10% of the plastics are recycled in the world and the rest ends up in landfills.
PHAs are biodegradable, bio-based and recyclable which makes them the most sustainable choice available. Unlike other bioplastics like PLA, we produce PHA from waste materials and by-products so we don’t create another problem like food scarcity to fight the plastic problem.
We have created a sustainable web through our process and this is how it looks:
Our revolutionary process helps us turn waste and by-products into polymers without using any fresh source of food.
We can use:
Organic Food waste
Beer industry waste
Dairy industry waste
Sugar industry waste
Patented conversion process
Through our patented conversion process we are able to create wastes from different industries into polymers by feeding our bacterias enough so they produce a high yield of PHA polymers.
Once we get our PHA granules, we compound them to match our consumer’s needs. We have explored some initial applications for PHA but possibilities are endless.
Our pellets can be used with existing machineries which is a boon the existing manufacturers as they can still make those wonderful products without any adjustment. Only this time the products are sustainable.
