The Urgent Need for Sustainable Waste Management
Ecosystems and human health are seriously at risk from the volume and complexity of waste generated by the modern economy. If not handled properly, this waste poses a great risk of contaminating both land and drinking water. The rise in solid waste production is a direct result of population growth, urbanization, and industrialization – trends that are steadily increasing worldwide.
The World Health Organization predicts that 2.01 billion tons of waste are produced annually, with a projected increase of 70% by 2050 to a staggering 3.4 billion tonnes. Despite this alarming statistic, 33% of the world’s solid waste is not properly managed, either through burning, open dumping, or simply not being accounted for. This neglect of waste management affects at least 2 billion people globally.
In developing nations, particularly in Sub-Saharan Africa, waste management is a pressing issue tackled through two primary systems. The first is the government-run official system, which struggles with limited financial resources to address the full scope of the problem. The second is the informal system involving private dealers and scavenger communities, playing a crucial role in the economy by recognizing the value of recyclable materials.
Transforming public concerns, preferences, knowledge, and habits is the crucial first step towards achieving a successful and sustainable municipal solid waste management system. Local governments play a vital role in providing the necessary infrastructure and engaging the public in recycling procedures. Incorporating circular economy principles into waste management is also crucial, creating a closed-loop system where resources are continuously recycled and repurposed.
Challenges and Opportunities in Mzuzu City, Malawi
The government of Malawi has taken significant steps towards managing solid waste in the country, enacting laws and establishing the National Sanitation Policy. However, the reality remains that solid waste management has been largely ineffective in most cities, including Mzuzu.
Studies have analyzed solid waste management strategies in Malawian townships, but these have primarily focused on one-time waste management strategies, neglecting more sustainable and cost-effective methods. Additionally, there is a lack of knowledge when it comes to categorizing waste for recycling into organic manure.
In 2017, the Malawian government launched the Mzuzu Waste Management Project, aimed at enhancing waste collection and disposal within the city. While the project has achieved some positive results, there is still much progress to be made in upgrading the city’s waste disposal infrastructure.
This study makes significant contributions to the literature by:
- Shedding light on the current challenges and opportunities in solid waste management in Mzuzu city through a comprehensive analysis of the factors contributing to waste accumulation and the transition to sustainable waste management systems.
- Presenting evidence to support a novel sustainable waste management technique, providing crucial insights into effective policies and legislation.
- Assessing the viability of implementing innovative, cost-effective recycling technologies in Mzuzu City, addressing issues such as community acceptance and practical barriers.
- Emphasizing the need for political will and institutional support in ensuring the success of sustainable waste management systems.
- Taking a holistic approach in evaluating the current state of waste management, recognizing the importance of involving all relevant stakeholders.
Theoretical Framework and Methodology
The study used the theory of collective action in waste management, pioneered by Olson in 1965. Olson introduced the concept of collective action in waste management, which highlights the difficulty of providing a public good within a large group without proper incentives. The Institutional Analysis and Development (IAD) framework was also utilized in organizing recycling and recovery programs, incorporating the principles of collective action for successful public participation.
The study employed a mixed methods design, combining quantitative and qualitative data collection methods. Participants were selected based on the principles of collective action theory, including households, businesses, and the Mzuzu City Council. A structured questionnaire was utilized for households, while interviews with key informants were conducted at the Mzuzu City Council.
The study area was Mzuzu city, which was purposefully selected due to its concerning level of solid waste buildup. A random sampling approach was used to select 400 participants from 5 different areas of the city, ensuring a comprehensive and unbiased representation of the population.
Key Findings
The study revealed several critical insights into the state of solid waste management in Mzuzu city:
Waste Disposal Practices and Public Bin Characteristics
The findings show that a significant percentage of respondents resort to disposing of their waste in less than ideal ways, such as shallow pits, open spaces, and the side of the road. This is partly due to the lack of accessibility to public waste cans in residential areas. Even among those who have access to public bins, the frequency of emptying is often inadequate, leading to overflowing waste.
Interestingly, a majority of respondents believe that the state of public waste bins directly affects waste management, suggesting an understanding of the importance of well-maintained infrastructure. However, a surprising 55% do not see a connection between the two, highlighting the need for education and awareness regarding the role of public waste bins in effective waste management.
Private Sector Involvement and Waste Collection Methods
The study found that the private sector plays a significant role in waste collection, with door-to-door collection being the most widely used technique. This demonstrates the diversity of waste collection strategies employed by private entities, in contrast with the limited capacity of the public sector.
Key informant interviews revealed that the private sector’s efficiency surpasses that of public waste collectors, primarily due to the availability of funds and necessary vehicles. This suggests that public-private partnerships could be a promising avenue for improving waste management in Mzuzu city.
Recycling and Circular Economy Practices
The study found that the absence of recycling practices is a major roadblock in implementing sustainable waste management in Mzuzu city. Despite the obvious benefits of recycling, it remains a foreign concept to many due to a lack of awareness and the misconception that it yields no tangible results.
Financial limitations and a lack of dedication were also cited as hindrances to adopting recycling habits. However, the survey results were largely positive, with the majority of participants expressing excitement about the potential for implementing a waste recycling system. This optimistic outlook highlights a promising opportunity for innovative waste management strategies.
Challenges and Barriers to Sustainable Waste Management
The study identified several key challenges that hinder the implementation of sustainable waste management systems in Mzuzu city:
- Lack of Coordination and Collaboration: The absence of coordination and communication between government, corporations, and communities is a major obstacle.
- Insufficient Waste Treatment and Disposal Capacity: The city’s waste treatment and disposal infrastructure is insufficient, leading to overflowing landfill sites.
- Limited Financial Resources: Inadequate financial support and resources for companies and individuals trying to implement sustainable waste management techniques is a significant barrier.
- Changing Attitudes and Habits: Transitioning long-standing attitudes and habits surrounding waste disposal is a challenging but necessary task.
Towards a Sustainable Future: Recommendations and Opportunities
Despite the challenges, the Mzuzu city council has made impressive strides towards improving the effectiveness of its waste management systems. The council has initiated several programs to promote sustainable practices, including waste separation at the source, establishing recycling centers, and collaborating with local entrepreneurs to create waste-to-product ventures.
To further enhance the sustainability of Mzuzu’s waste management, the study recommends the following:
