Rigel Bioenviron Solutions Pvt. Ltd. is a Start-Up in the field of biotechnology in India, venturing into Bio Polymers, Bio Chemicals and Environment. Our Aim is to valorize organic wastes in to various value added products. Such as,

  • Biopolymer Production
  • Value Recovery From Organic Wastes

Rigel is presently working on a Technology Scale–Up Project, which is to produce PHA Bioplastics from Agro Wastewaters. We have received prestigious BIRAC BIG 16 Grant from DST, Govt. of India for the prototype Scale Up of this State of the Art Technology, which is already patented and have a low cost of production.

The process also advocates for carbon sequestration and low carbon Foot Print – yielding GREEN PLASTICS.

This next gen bioplastic PHA i,e polyhydroxy alkanoates is 100% biodegradable and having very good similarity in properties with polypropylene or conventional plastic. Presently PHA is being produced from pure substrates thus at increased production cost and we promise to produce it from waste.

The proposed process is widely versatile. Can be adapted for various wastes/wastewaters like waste potato & grains, food processing, dairy, agro-chemicals, brewery, vegetable oil, grain based distillery effluents, sewage etc., thus having high ROI from Wastewater Treatment Facility (WWTP). Otherwise, a WWTP is a sunk cost for any industry.

We are aiming to elevate this technology to Commercial DEMO Plant level to set up specific agro wastes to biopolymer production plant.

Problems we solve

At Rigel BioEnviron Solutions Pvt. Ltd. we predominantly focus on following value added product/service offerings in the Bioplastics sector:

Category A:

Turn key project / Consultancy for manufacturing and marketing products made from conventional bioplastic resins:
Sourcing of the raw materials (including resins and additives) / intermediate compound / finished products made from Bioplastics:
These include starch and some other bioplastics used currently in market to formulate products used primarily for single use plastics such as

  • Packaging: carry bags, garbage bags, nursery bags
  • Disposable cutlery items such as plates, glasses, spoons etc.

Formulation support for materials to make above mentioned products
Recommendation of the required machinery and equipment
Identifying the market and marketing of products manufactured by our clients

Category B:

Technology development to produce next generation bioplastic resins which will have extended benefits over conventional bioplastic resins towards faster biodegradability, better mechanical and physical properties and better economics
