  • Mulch or Soil Additive

​

  • Landscaping applications. Attractive and doesn’t break down.

​

  • Glass mulch keeps insects, slugs, and other weeds from coming up to the plants.

​

  • Glass creates an insulated layer of mulch to protect the plant’s roots from extreme temperatures.
  • Glass sand retains moisture on the particle surfaces.  It provides water and available silica for the plant’s growth

​

  • Mix glass sand with compost to make a soil blend that includes organics nutrients from the compost and filtration and water retention from the glass sand.

  • Glass sand retains moisture on the particle surfaces. 
  • It provides available silica for the plant’s growth
    • Silicic Acid – Silicon attached to Oxide (=O) and Hydroxyl (-OH) groups.
    • Silicic acid is a powerful plant bio stimulant that can promote plant growth and protect crops from pests

  • Glass – Compost Mix

  • Locally-Sourced Recycled Soil for Green Stormwater Infrastructure.
  • A soil blend with organics from compost and glass sand for filtration and water retention.

​

The soil blend is designed to support plant growth and stormwater infiltration.
