Description

According to a study released in 2007 by Groupe AGECO on issues in the vegetable production industry, 80% of producers manage post harvest residues and 38% are very concerned about environmental standards in this regard. Potato producers are no exception. Managing potato residues is particularly problematic due to their large quantity. (65,000/yr.) Because of their water content, they cannot be composted, and stockpiling them involves significant environmental and phytosanitary risks. Managing potato residues is therefore a big challenge, which will only increase with the enforcement of the Québec Residual Materials Waste Management Policy. This will put increased pressure on the agricultural community to use external residual materials that will compete with on-farm waste. So it is essential that potato residues are well positioned on the organic waste market. To this end, the residues must be transformed, using an available, low-cost process, into a product that is easy to store, transport, and handle and has recognized value as feed, fertilizer, or a source of energy.

Objective(s)

  • Facilitate the storage and use of potato residues through a pelleting process and promote use of the solid pelleted fraction by determining its safety and nutritional, fertilizing, and energetic value and use of the liquid fraction by studying its agronomic value
  • Conduct an economic substitution analysis with regard to competing products according to the various uses explored
