An investigation into the environmental impacts of container choices on the UBC Farm Ritland, Kelvin; Oliveira, Reid; Johnson, Quinn; Jiang, Jiahui; Foolad, Yasaman

Abstract

The UBC farm uses plastic Rubbermaid totes and InterCrate crates for a variety of tasks such as harvest, storage, and shipping. However, they were concerned with the containers' economic, social, and environmental costs. This report presents the evaluation of the environmental costs of using reusable plastic containers which need to be continually washed in comparison to four other possible alternatives: cardboard boxes, wax-lined cardboard boxes, wooden boxes, and cardboard boxes with biodegradable liners. Due to food safety considerations and lack of structural practicality, cardboard boxes, wooden boxes and biodegradable liners were eliminated as options. Therefore, wax lined cardboard boxes were left as the most favorable alternative. Closer investigation of plastic containers versus waxed cardboard boxes was then done through comparative analysis of the environmental impacts on a scale based on solid waste, water emissions, air emissions, water usage, and CO2 emissions. This analysis showed that the plastic containers yielded far better environmental results in all factors except water usage by a factor of about 15. Overall, the recommendation presented is to continue with the current practice of plastic containers, favouring lighter local ones where possible.
