Composting

You are here:

In nature, nothing is wasted. Everything is returned to the soil

through nature’s recycling process — composting.

 

Compost is the end product of a natural process that reduces organic waste to humus. Compost contains plant nutrients, soil microbes and organic fibre for building healthy soil. Up to 30% of the garbage produced in Regina households is leaf and yard waste that can be diverted from the landfill and recycled into nutrient-rich compost. Imagine one third less waste to lug to the curb for collection!

 

Composting at PV

PV Waste Solutions accepts organic food waste (see list below) , leaf and yard waste and clean biodegradable waste from construction and demolition operations from commercial haulers and residents. All organic materials are piled into long rows (windrows) and composted at our soil bio-remediation and compost site. These windrows reach temperatures of 55 degrees celsius and higher (PFRP Process) and are turned periodically to improve porosity and oxygen content, mix in or remove moisture, and redistribute cooler and hotter portions of the pile.

 

Our finished compost is tested on a regular basis and we have consistently produced Category “A” Compost. We are members of both the Compost Council of Canada and the Compost Quality Alliance.  Our compost can be added to your yards and gardens and provide a number of environmental benefits. See “Benefits of Composting” below to learn why composting our organic waste is a vital component of preserving and protecting our environment.

Commercial Haulers

PV Waste Solutions accepts organic food waste from restaurants ,grocery stores, offices and City of Regina residents through our curbside collection program. We also accept yard waste from local landscaping service providers, City of Regina Leaf and Yard Waste Depots, as well as construction and demolition waste from commercial haulers. Acceptable organic waste materials can be found in the list of residential materials below. Construction and demolition materials that may be accepted for composting include clean wood waste, wood pallets, drywall ,and cardboard.

 

Residential Leaf & Yard Waste

Yard waste from the City of Regina depot program.

PV has cultivated several relationships over the years to ensure leaf and yard waste is diverted from the landfill and recycled at our compost facility. We partner with the City of Regina to compost the yard waste collected from the City’s Leaf & Yard Waste Depots each spring and fall. We also partner with local companies and community gardens wishing to divert their organic waste. Recently we have started working with grocery stores and restaurants helping them reach their sustainability goals.

We also accept residential leaf and yard waste at our Bioremediation & Compost Facility located a few kilometers west of Regina at the BEST Landfarm. Choosing PV will allow you to avoid the long line-up at the landfill and ensure that your yard waste will be used to create something that benefits our environment — compost!

* Please note: The charge for residential yard waste is $10 per truck load. All yard waste must be in paper bags or reusable containers that can be emptied on site. Plastic bags will need to be opened and emptied on site by the resident.

 

Vermicomposting

PV’s large scale vermicomposting unit. We’re worm farmers!

“Vermi” is the Latin word for worm. Vermicomposting is the process of composting food scraps using red wiggler worms that can eat and expel close to their own weight every day. The worms work in partnership with fungi, bacteria and other microbes to breakdown food scraps into worm casting or worm “poop” – the most nutrient-rich compost there is!

PV Waste Solutions has recently purchased a large scale vermicomposting unit and will begin composting food waste and farming red wiggler worms in the New Year.

PV also operates our Clean Earth Warriors program to work with Regina schools to bring small scale vermicompost bins into classrooms. Check out the In Our Community – Environmental Education page to find out more about this program.

 

Benefits of Composting

  • Decreases waste sent to landfills
    • Organic waste breaks down in an anaerobic environment (no oxygen) in a landfill. The organic waste turns into a toxic liquid – “leachate” – that leaks down though the landfill potentially polluting nearby water waters and releases methane (a dangerous greenhouse gas) into the atmosphere.
  • Prevents soil erosion
    • Soil is held together by its organic matter. Soil with high organic content is less likely to be impacted by water run-off or wind erosion.
  • Increases soil’s ability to hold water
    • Compost absorbs water better than soil and can hold almost twice its weight in water.
  • Mitigates the risk of drought or floods
    • By increasing the amount of water that can be held in the soil, compost can help to mitigate the risk of drought and floods.
  • Increases microbes, nutrients and minerals in the soil
    • Compost promotes healthy microbial activity in soil, making valuable nutrients and minerals available to plant roots.
  • Improves soil structure
    • By adding organic matter to the soil, compost improves the structure of the soil. Compost will helps avoid soil compaction by breaking up heavy clay soils and binding sandy soils.
  • Restores soil food web 
    • Compost increases biological activity in the soil and restores the soil food web by attracting beneficial microbes, bacteria, earthworms, insects and birds.
  • Neutralizes soil toxins and reduces use of chemical fertilizers
    • Compost locks toxins in the soil in a form unable to harm plants and can assist in repairing soils contaminated with chemical fertilizers and pesticides.
  • Stimulates plant growth
    • By increasing the water-holding capacity, organic matter and biological activity of soil, compost suppresses diseases, pests and weeds, and increases the ability of plants to take up nutrients and minerals.
