Compost Helps the Environment!

Compost is organic material that can be added to soil to help plants grow. Food scraps and yard waste together currently make up more than 30 percent of what we throw away and could be composted instead. Making compost keeps these materials out of landfills where they take up space and release methane, a potent greenhouse gas.


composting is smart

Mixing compost into your soil!
  • adds valuable nutrients to your soil, acting as a natural slow – release fertilizer for plants and microbes.
  • reduces the need for pesticides and synthetic fertilizers.
  • enriches soil and promotes healthy plant growth (more fruit and vegetables—tastier, too!)
  • helps to regulate and neutralize the acid and alkaline levels in you soil.
  • saves water: nutrient rich soil requires less irrigation.
  • healthy root growth in you garden means less erosion.
  • plants grown in compost-amended soil tend to be more resilient to diseases, pests, and fungi.
Do your part. Keep the green stream clean.

Only place items that were once alive into the Organics collection containers. The material is taken to a facility to create compost.
