Our Interventions

Meeting the industry where the harm happens.

We do not seek to end extraction. We seek to make it more considerate. Our programmes work alongside operators, not against them.

Industry Engagement

Supporting a transition, not demanding one.

We collaborate with global producers, aggregate suppliers, and developers to improve practices at every stage where a rock is acted upon.

Our engagement model is deliberately non-adversarial. Operators face real commercial constraints, and a programme that ignores those constraints helps no rocks. We provide consultation on best practices, implementation strategies, and free services and equipment to aid the transition — meeting each operator at their current stage of the welfare-improvement process.

Consultation

Assessment

We survey a site's current methods and identify the points of greatest avoidable distress — typically blasting intensity and crusher throughput.

Implementation

Transition

We supply protocols, staff training, and, where relevant, equipment to shift toward lower-distress methods at little or no cost to the operator.

Recognition

Certification

Compliant operators may display our voluntary Certified Gentle Stone mark across three tiers: Bronze, Silver, and Bedrock.


Flagship Programme

Humane Quarrying Initiative

The single largest source of acute rock distress is extraction itself. The Humane Quarrying Initiative is our direct response.

We promote a set of low-distress practices: cleaving along natural fracture planes rather than against the grain; introducing site acclimatisation periods before major works; and phasing out high-fragmentation blasting wherever gentler mechanical separation is viable. Operators receive the full protocol library and on-site training at no charge.

The programme is live at three partner sites, with a further five in assessment.

A Public Commitment

The Gentle Extraction Pledge.

This page celebrates producers who have committed to lower-distress extraction, and highlights suppliers and developers who have implemented policies to phase out the highest-distress practice of all — uncontrolled high-fragmentation blasting — from their supply chains.

Committed Operator

Threnody Aggregates

First operator to adopt fracture-plane cleaving across an entire site. Certified Bedrock tier.

Since Q1 2026
Committed Supplier

Carrow Stone & Lime

Eliminated high-fragmentation blasting from its dimension-stone line; transitioned to wire-saw extraction.

Silver tier
Committed Developer

Mistlow Build Group

Now sources only Certified Gentle Stone aggregate for residential foundations.

Bronze tier
In Assessment

Five further operators

Currently undergoing site assessment ahead of a planned commitment in the next quarter.

Rock Rewilding

Where extraction has already displaced a rock of high geological coherence, we ask a simple question: can it be returned?

Our Rewilding programme identifies displaced boulders of particular structural or lithological significance and, where feasible, returns them toward their original context. The programme is small — eleven boulders to date — and we describe it honestly as a pilot. We do not claim the returned rock is "happier." We claim only that it is, once more, where it belongs.

Engagement is free, confidential, and non-binding. Most operators begin with a no-obligation site assessment.
