At Corker, we believe that truly sustainable products begin with responsible sourcing. As a family
business, we take pride in knowing where our materials come from and how they’re produced. We
carefully select suppliers who share our values, ensuring that every material we offer meets strict
environmental and ethical standards.
From local partnerships to international suppliers, we prioritise transparency and sustainability at
every step of our supply chain.
Our Sourcing Principles
Our products complete a natural cycle that mimics the way
resources flow in nature:
Mushroom Compost
We prioritize renewable, recycled, and sustainably harvested materials across our entire product range. From FSC-certified timber to recycled green waste, we select materials that minimise environmental impact without compromising on quality.
Ethical Labor Practices
We work with suppliers who ensure fair wages and safe working conditions for everyone involved in creating our products. We believe that sustainable products should support sustainable livelihoods too.
Supply Chain Transparency
We track our materials from source to customer, ensuring accountability at every stage. This attention to detail allows us to stand behind every product with confidence and provide our customers with clear information about their purchases.
