Biomass fuel pellets.
From farm waste to clean fuel.

Rispri Labs delivers binder-free fuel pellets from banana root and other agricultural waste, developed with ICT Mumbai. A sulphur-free solid fuel for boilers, kilns and power plant co-firing.

Biomass fuel pellets

What it means for you

Farm waste into clean fuel pellets.

16.3 MJ/kg

in the range of Indian thermal coal.

No sulphur

detected in the pellets, so no SO₂ from the stack.

Waste → income

Banana root waste becomes a saleable fuel.

Performance

Cleaner fuel, from waste.

Banana root and similar farm waste is usually burnt in the field. Pelletised, it becomes a dense, durable, sulphur-free fuel that can replace coal in boilers and kilns.

Challenge and response

The problems this solves.

  1. 01
    The challenge

    Farm waste is burnt in the field, polluting the air.

    How we solve it

    Collect it and turn it into fuel pellets.

  2. 02
    The challenge

    Coal brings sulphur emissions and price swings.

    How we solve it

    Sulphur-free biomass replaces part of the coal.

  3. 03
    The challenge

    Loose biomass is bulky and hard to feed.

    How we solve it

    Dense, durable pellets store, transport and feed easily.

  4. 04
    The challenge

    Binders add cost and ash.

    How we solve it

    Pellets hold together with no added binder.

How it works

The process, step by step.

  1. 1

    Collect

    Banana roots and other farm waste are gathered after harvest.

  2. 2

    Prepare

    The biomass is dried and ground to size.

  3. 3

    Pelletise

    It is pressed into pellets with no added binder.

  4. 4

    Fire

    Pellets feed boilers, kilns or co-firing systems.

Standards and regulations

Designed around the rules that apply to you.

We design each system to meet your consent conditions and the regulations for your sector, and our laboratory reports against them.

  • Ministry of Power biomass co-firing policyMandated co-firing of biomass pellets in coal-fired plants.
  • SAMARTH missionNational mission on biomass use in thermal power plants.
  • CAQM fuel directionsApproved fuels for industry in the National Capital Region.
  • Crop residue management guidelinesMeasures to stop open burning of farm residue.

Industries served

Built for the sectors that need it most.

Why Rispri

Institute science. Industrial delivery.

Institute-developed technology

Built on patented and peer-reviewed research from our partnership with ICT Mumbai.

Tested on your stream

Our accredited laboratory characterises your water or waste before design and verifies results after.

Engineering since 1999

The team that builds ETPs, STPs and ZLD plants across India takes each solution from pilot to full scale.

One accountable partner

Design, supply, installation, commissioning, operation and testing under one contract.

Questions

Frequently asked questions.

What is the calorific value?

About 16.3 MJ/kg for banana-root pellets.

Do the pellets need a binder?

No. They are binder-free and reach about 98% durability.

Do they contain sulphur?

No sulphur was detected in the pellets.

Can other farm waste be used?

Yes. The process can be adapted to other agricultural residues; we test them in our laboratory.

How ready is it?

Pellet quality has been validated in trials. We scale it through a pilot pellet line with your feedstock.
