Case study
Virentis Climate
From a corporate site for a multi-division climate group to an authenticated client portal for carbon-credit customers.
By Mike Hubbard · Updated 9 September 2026

A website that sells while you sleep: interactive tools that let a prospect build their own business case.

Problem
Virentis operates across several distinct divisions — carbon credits, pyrolysis and aerogel materials — each with its own audience and its own story. The group needed a single corporate presence that made the divisions legible without flattening them.
Behind the brand sat a second, harder problem: carbon-credit customers needed a private place to see their own information, rather than receiving it through email threads and attachments.
What we built
The public site
First, the corporate site: a clear structure for a multi-division group spanning materials, carbon credits, pyrolysis and fuels, written and designed so a visitor understands what each division does within a few seconds.
Embedded in the public site sit two interactive tools, built bespoke for Virentis rather than assembled from off-the-shelf widgets: a pyrolysis plant configurator and a carbon-credit revenue calculator. They turn a prospect's own numbers — plant size, feedstock, throughput, yield — into a live business case with cost, output and revenue figures, before anyone speaks to a salesperson.



The client portal
Then the client portal at portal.virentis.uk — a secure, role-based space where Virentis and its recycling clients track carbon-credit projects through their lifecycle, see credits issued and revenue shares, and read daily market intelligence. It replaces spreadsheets and email updates with one shared source of truth.



Client names blurred.
Security & governance
The portal is multi-tenant, with per-client data isolation and role-based access so each organisation only sees its own projects and revenue. It was built with the standard security wrap: row-level access control enabled and policy-reviewed on every table, secrets held server-side, authentication hardened, and security headers configured before launch.
A pre-launch scan was run against the portal, and the engagement closed with a written security statement describing the protections in place.
Outcome
A multi-division climate group now presents itself coherently in public, qualifies its own prospects through interactive tools, and serves its carbon-credit customers privately through one system.
