Waste-to-value

Low-energy refining for agricultural, forest and marine side streams. From disposal cost to revenue.

BrightValue · Cost avoided

The side stream you pay to dispose of becomes feedstock.

What we do with it

BrightValue · Lower CO₂

Refined where the waste is, with no low-value tonnes shipped across the continent.

How a project runs

The service

BrightValue, co-development service.

The Minimill is a containerised biorefinery, deployed where the side stream is. It refines the raw biomass into building blocks for material formulations, with no need to ship low-value tonnes to a central plant.

Every side stream is different, so there is no catalogue to buy from. Brightplus assesses your stream in its lab, designs the refining process around it, and builds that process into a Minimill on your site.

The range

What side streams become.

Also developed a soy-oil polyester plasticiser, and PHA bioplastic from captured CO₂.

How a project runs

From a sample to a running Minimill.

Three phases, each ending in an output you decide on. Take one, several or all of them, or start at the pilot if your concept is further along.

  1. 01

    Assess

    We audit your side stream’s quality and volume in the lab, then draw up the process and the screening economics.

  2. 02

    Pilot

    We build the Minimill on your site and run the first batches, then optimise it to full capacity.

  3. 03

    Scale

    The mill is replicated to further lines or sites, and the refined fractions are sold.

Where most projects start

Start with a material assessment.

10 kg of your side stream, 2 to 3 weeks, under a material transfer agreement. You get back a material report and a potential estimate.

Your brief

Describe your side stream.

Pick what it is, what form it takes and when it arrives. The brief goes straight to the valorisation team.

    BrightValue, for your side stream

    Every stream starts the same way: a 10 kg sample and a material report.

    ProcessFive stages, entered anywhere

    Take one stage, several or all five. A short desktop study is built into the pilot if you start there. Each stage ends in an output, so the decision to continue is made on evidence rather than on a plan.

    The MinimillYours, under licence or bought
    • Licence: you own the Minimill and run the refining process under a Brightplus licence, with royalties on the output. Brightplus maintains the process and upgrades it for new needs.
    • Buy: the Minimill and the process outright.
    • Refined fractions can be formulated into materials by Brightplus as an added service.
    In-house testingWhat we measure
    • Viscosity, solid content, purity and OH value.
    • Spray and bar coating tests, and curing.
    • Mechanical testing and weather-chamber ageing.
    • Accredited partner labs for final validation.
    FundingPublic co-funding
    • Valorisation projects are often part-funded through public instruments, national or EU.
    • Brightplus works as a subcontractor to your project, not as a funded partner. You buy the work; any funding is yours.
    • We help with the funding application.

    Tell us about your side stream.

    What it is, how much of it there is and when it arrives. We will tell you what it could become, and if the answer is nothing worth refining, we will say so.
