Granulated Cork - Recycled, Mixed Grain, Dark | Cubic Foot

Dark Recycled Granulated Cork, also known as cork grain, is a lightweight, eco-conscious natural material composed of ground cork bark, recycled cork stoppers, and cork off-cuts, repurposed from cork waste that would otherwise go to landfill. The mixed grain size and mixed density of this recycled grade make it a versatile, cost-effective option across industrial, horticultural, creative, and recreational applications where precise grain uniformity is not required. In garden soil, granulated cork improves aeration and moisture retention to promote healthy plant growth without synthetic additives. In film, theatre, and stage set design, it simulates realistic sand, dirt, and terrain at a fraction of the weight of real materials. Please note that as a recycled product, this cork grain may appear slightly darker or dirtier than standard non-recycled granulated cork grades — this is a normal characteristic of recycled material and not a defect. Each cubic foot contains approximately 10 pounds of cork grain, though this varies depending on grain composition, and would fit a 12in × 12in × 12in carton. Cork grain may be a mix of compressed and loose grain, and orders of more than one cubic foot may be bulk packed into a single carton. Perfect for gardening and horticulture, film and theatre set design, industrial components and fillers, synthetic turf infill, playground surfacing, oil spill absorption, and any application requiring a lightweight, natural, and sustainable granular cork material where mixed grain size is acceptable.

Why Choose Dark Recycled Granulated Cork — Mixed Grain?

• Recycled and repurposed cork waste — grinding and reusing cork bark, stoppers, and off-cuts keeps material out of landfills and puts it to productive use
• Mixed grain size and density makes this a versatile, cost-effective option for applications where precise grain uniformity is not required
• Improves soil aeration and moisture retention when mixed with garden soil, supporting healthy plant growth without synthetic additives or chemicals
• Ideal for film, theatre, and stage set design — simulates realistic sand and terrain textures at a fraction of the weight and cost of real materials
• Natural alternative to rubber infill for synthetic turf and playground surfacing, providing a lightweight, biodegradable, and non-toxic playing surface
• Absorbs oil quickly, making it effective for small domestic and industrial oil spill cleanup

Recycled Granulated Cork outperforms rubber, sand, and synthetic granular materials by combining genuine lightweight versatility with a fully natural, recycled composition suitable for horticultural, industrial, creative, and recreational use.
