  • From Waste to Wealth: Navigating Nigeria’s Circular Food Frontier

    Host: Dr. Sama A, Guest: Iyanuoluwa Faith Abimbola | The Sustainability Side, Episode 10 Recap

    Every year, Nigeria generates over 32 million tons of solid waste. Nearly half of that is food waste, yet less than 10% is currently recycled. That is more than just a statistic; it is a staggering amount of “wasted potential” ending up in landfills and waterways.

    But what if we stopped seeing waste as a problem and started seeing it as a resource? On this episode of The Sustainability Side, we dive into the Circular Shift, a movement to re-imagine Nigerian food systems to reduce waste, regenerate ecosystems, and build a resilient future.

    We were joined by Iyanuoluwa Faith Abimbola, a fisheries scientist and sustainability enthusiast whose work bridges the gap between aquaculture health and eco friendly innovation.

    1. The Cultural Shift: It’s Not New, It’s Nigerian

    While “Circular Economy” sounds like a high-tech global trend, Faith points out that its principles have been part of the Nigerian daily life for generations.

    • The Traditional Roots: From handing down clothes to younger siblings to repurposing old fabrics as rags, the concept of a “total life cycle” is already built into our culture.
    • The Convenience Trap: The rise of plastic sachet water was born from a need for convenience. However, before the sachet, Nigerians relied on refillable pots and pails, a naturally circular system.
    • The Opportunity: Shifting back to sustainability doesn’t mean “dehydrating the poor”; it means businesses must innovate and ideate around refill stations and biodegradable alternatives that thrive in our climate.

    2. The 4 Untapped “Gold Mines” in Food Waste

    Where others see trash, Faith sees a commercial treasure trove. She highlighted four specific waste streams that are currently undervalued in Nigeria:

    • Corn Cobs: Often discarded, these can be processed into animal feed or used to create fuel briquettes for energy.
    • Cashew Apples: While the nuts are exported, the apples are often left to rot, releasing methane. They can be transformed into juices or ethanol.
    • Fishery Waste: Fish scales and heads from markets like Makoko are perfect feed-stock for biogas plants to generate electricity.
    • Shrimp Shells: Rich in chitosan, these shells are a premium source for soil conditioners and regenerative organic manure.

    3. The Investor’s Reality Check: Do the “Dirty Work”

    If you are an aspiring eco-entrepreneur, Faith’s advice is grounded in the hard reality of the Nigerian market. Green investors aren’t just chasing elegant ideas; they are backing execution.

    • Access Over Apps: Investors care less about a fancy SAS platform and more about feed-stock access. If you can prove you have a signed agreement to collect 1,000 tons of waste, you are investable.
    • The “Dirty Job” Model: The real money is made in the downstream—the physical collection and processing. Technology should be a tool to make this “dirty work” seamless, not a replacement for it.
    • Unit Economics: A model that works profitably for 10 tons a week is far more attractive to a funder than a grand “scale-up” plan that hasn’t moved a single bag of waste yet.

    4. Your Action Plan: Starting with Zero Capital

    You don’t need a massive grant to join the circular movement. Faith suggests looking at the waste systems already in your backyard:

    • Identify the Stream: Visit local markets (like the grain or fish markets) where waste is currently a “menace” to the sellers. They will often give you the waste for free just to clear the space.
    • Focus on the “Small Win”: Start by collecting specific waste for existing biogas plants or organic farmers.
    • The Mindset Breakthrough: Stop waiting for the government to “do business.” The government’s role is to create an enabling environment; the individual’s role is to provide the value and the solution.

    Conclusion: Reimagining Sustainability as a Culture

    Sustainability in Nigeria isn’t just about protecting the planet; it’s about building smarter, more resilient communities. By turning our “waste” into “wealth,” we move toward a future where circularity isn’t just a choice—it’s our culture.

    Every step toward circularity, no matter how small, helps build a better way forward. As Faith prepares for her PhD journey in ocean management, her message remains: Sustainability is not just mine, it’s ours.

  • From Disaster to Opportunity: Turning Flood-Damaged E-Waste into Circular Gold

    Host: Dr. Sama A, Guest: Dr. Nurul Aini Osman | The Sustainability Side, Episode 7 Recap

    Every year, the world generates over 50 million tons of electronic waste, and less than 20% is recycled properly. But imagine what happens when a devastating flood hits.

    Suddenly, that global crisis becomes a local one. Damaged electronics pile up, toxic substances leak into the environment, and vulnerable communities are left with yet another layer of disaster to manage.

    In this episode of The Sustainability Side, we tackle a powerful question: How can flood-affected communities turn the challenge of e-waste into an opportunity for empowerment and circular growth?

    We were joined by Dr. Nurul Aini Osman, a senior lecturer at Taylor’s University Malaysia and a leading voice in sustainable e-waste management. Her work bridges the gap between disaster recovery and community-driven innovation.

    1. The Hidden Crisis: Why Floods Worsen E-Waste

    When we think of floods, we usually picture damaged homes or ruined roads. But Dr. Nurul points out a less visible impact: our electronics.

    The Submergence Problem

    When household appliances like TVs, computers, or air conditioners are submerged in dirty floodwater, they suffer from rapid corrosion and short circuits. Most people assume they are “beyond repair.”

    The “Pressure” Effect

    During the panic of post-flood cleanup, waste management systems come under extreme pressure. Without a plan, hazardous e-waste—filled with lead, mercury, and flame retardants—gets mixed with general debris. This leads to:

    • Soil and Water Contamination: Toxic chemicals leaching into natural resources.
    • Health Risks: Communities unknowingly handling dangerous materials.

    2. Turning the Tide: The Community Hub Model

    Dr. Nurul shared a brilliant case study from her work in Hulu Langat, Malaysia, an area frequently hit by floods. Instead of viewing damaged electronics as a burden, they built a framework for resilience.

    The E-Waste Recycling Hub

    The community established local hubs strategically placed outside high-flood-risk zones. These hubs serve three main purposes:

    1. Skills Training: Local youth are trained in dismantling, sorting, and identifying e-waste categories.
    2. Repair & Upcycling: Providing technical vocational education to fix what can be saved.
    3. Incentive Systems: Partnering with licensed recyclers to offer vouchers or discounts to families who return their damaged goods properly.

    This turns a cleanup chore into a local economy that supports livelihoods while protecting the environment.

    3. Policy & Participation: The “Japan Model”

    Where does the rest of the world stand? Dr. Nurul highlights Japan as the gold standard for e-waste management in Asia.

    The secret? Extended Producer Responsibility (EPR). In this model, the companies that make the electronics are responsible for their entire lifecycle. Recycling fees are often built into the purchase price, and users get incentives for returning old devices.

    The Lesson for Us: While we wait for full-scale government policies like EPR to hit every region, the “grassroots” participation of communities is the foundation. As Dr. Nurul says, “Sustainability isn’t just about systems; it’s about people.”

    4. Your Action Plan: How to be “Flood-Ready”

    Whether you live in a flood-prone area or just want to manage your household tech better, Dr. Nurul suggests starting small:

    • The Labeling Habit: Identify your major electronics. If a flood warning hits, move them to higher ground or have a designated “collection point” to prevent them from being swept away.
    • Know Your Channels: Don’t just throw an old phone in the trash. Use local e-waste apps (like Malaysia’s e-waste app) or find licensed recyclers in your area.
    • Mindset Shift: Stop seeing old tech as “garbage.” See it as a resource that contains valuable metals and components that belong back in the loop.

    Conclusion: Reimagining Waste as a Resource

    Disaster recovery doesn’t just have to be about getting back to “normal.” It can be about building back smarter. By integrating circular economy principles into disaster management, we turn a post-flood crisis into a catalyst for new skills, safer environments, and more resilient communities.

    Every action counts. Whether it’s repairing a device or advocating for better local policies, you are helping build a sustainable future.
