Reducing consumption of inputs at source
Reduction of solid and liquid wastes from a fruit juice processing plant depends first and foremost on using smaller amounts of the input materials employed in making and marketing the finished products. This reduction is structured around two factors: packaging (containers) and the amount of water used for the chilling and purification processes.
With regard to containers, sustained efforts have been made over the past few years to reduce their weight. Examples include:
- Reduction of the weight of 300 ml, 1.89 l and 2 l plastic bottles and caps. This saves 290 tons of plastic per year.
- Reduction in the size of cardboard boxes and the amounts of plastic wrap and glue used.
- Major reduction of waste from Tetra Pak machines at the end of production runs (data available on request).
With regard to water consumption per litre of finished product on the market, we may state with confidence that the Mont-Rouge plant consumes up to 30% less water per litre of processed juice than manufacturers in Europe, where water resources are scarce and costly.
Improving wastewater treatment
For some time, special efforts have been made to improve purification performance at our wastewater treatment plant. As a result of major investments, water purity has risen from 75% to 92%. What this means is that besides lowering the overall amount of wastewater, we’re substantially upgrading the quality of the effluents.
Collection and recovery of inorganic waste (containers and packaging)
For over 10 years, A. Lassonde Inc. has been actively concerned with the management of waste materials. The following materials are recovered:
- Unused cardboard
- PET plastic
- LDPE plastic
- Steel barrels
- Plastic barrels
- Wooden palettes
- Waste oil of all kinds
- Inks and solvents
- Laboratory chemical residues
Year in, year out, the sale of these recoverable materials largely covers the costs associated with the proper disposal of oil, batteries, solvents and other forms of hazardous waste. The overall balance sheet for waste management is therefore positive in an economic as well as an environmental sense.
Collection and recovery of organic waste
A major portion of the waste produced consists of organic residues from the processing of fruit (apples, cranberries and blueberries). These residues are supplied free of charge to cattle breeders in the region. Demand for these products largely exceeds supply. In addition we take part in the segregated waste collection program run by Éco Entreprises Québec.
