Achievements of Canada’s municipal solid waste management: how a policy and technology synergy can inform a new municipal solid waste management framework for Cameroon
摘要
Cameroon’s sustained economic growth following the successful completion of its second Structural Adjustment Programme with the International Monetary Fund (IMF) has resulted in increased wealth generation accompanied by a corresponding rise in municipal solid waste. To address the growing challenges of waste management, there is a critical need for comprehensive policy reform. Drawing inspiration from international best practices, this paper examines Canada’s experience as a model for potential adaptation in Cameroon. Canada’s waste management system, guided primarily by the Canadian Environmental Protection Act (CEPA, 1991), has evolved through a combination of federal legislation, provincial initiatives, and municipal implementation. Key strategies such as the Zero Waste initiative, Extended Producer Responsibility (EPR), the adoption of Circular Economy principles and the deployment of colour-coded bin systems have collectively contributed to significant improvements in waste diversion and reduction of landfill dependency. Between 2002 and 2018, Canada’s total diverted waste increased from 6.6 million tonnes to a national diversion rate of 48%. A report by the Fraser Institute indicates that several provinces including Quebec, Ontario, Saskatchewan, British Columbia and Manitoba, achieved reductions in per capita waste generation during this period. Notably, by 2020, Prince Edward Island, British Columbia and Nova Scotia reported diversion rates of 51%, 39% and 43%, respectively. Despite continued increases in absolute volumes of landfilled waste, Canada’s efforts demonstrate a decoupling of waste generation from economic output. This paper draws on Canada’s achievements and enabling policy environment to propose a contextualized waste management framework for Cameroon, with the goal of promoting sustainable development and environmental resilience.
