Clinker substitution (SCMs) vs Carbon capture & storage (CCS)

Two routes to the same tonne of CO2 — at very different cost, speed and risk. The honest sequencing answer is usually «cheaper one first, it funds the other».

Side by side

	Clinker substitution (SCMs)	Carbon capture & storage (CCS)
Abatement cost	€0–30/t	€60–140/t
Addresses	20–35% of cement CO2	50–95% of a stream
Payback	1–3 yr	>10 yr, policy-dependent
Best for

Verdict: start with Clinker substitution (SCMs) — lower €/t and faster payback; bank its savings toward the structural step. Sequencing beats either/or: every tonne the cheap measure removes shrinks the expensive one's required size.

Inzonex removable modular insulation on industrial equipment

Cut the tonnes at the source

Hot industrial equipment? Cut the heat loss.

Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes patented (UK GB2508992.1) removable modular insulation — snap-fastened covers engineered per temperature tier, not generic off-the-shelf jackets:

Up to 90% less heat loss from insulated surfaces
Surface temperature ≤45 °C — touch-safe for workers (EN ISO 13732-1)
6× faster maintenance access than fixed cut-and-weld lagging — unclips and refits in minutes, no destruction
Inspectable — comes off to check for corrosion under insulation, then refits like-new (generic jackets often don't survive removal)
Typical payback under 2 years (some 9–11 months)
