Waste-to-Energy: Pros and Cons of This Emerging Technology

Image
  By Best Precious Think about your own trash can: after removing all that could be recycled, there is still trash left-food scraps, broken plastic, old clothes. We all understand very well that waste is a huge problem: landfills are filling up, trash too often ends up polluting our environment, and at the same time, the world is always in search of new ways to produce energy. That is where Waste-to-Energy comes in. WTE technology transforms the non-recyclable wastes into utilizable forms of energy like electricity, heat, or fuel. As WTE is a new technology, therefore, it entails certain benefits and drawbacks associated with WTE. THE PROS 1. Waste reduction to landfill: Waste-to-energy technology reduces the environmental as well as space-related problems associated with landfills, including water groundwater contamination and lack of land. 2. Renewable energy generation: It generates energy from waste that cannot be recycled. Energy harnessed in this manner can also be used for h...

Climate Change: Farmer’s Peril and Food Scarcity

Image
  By Ruth Irimonre Farmers are impacted by climate change, which jeopardizes food security. Food shortages are caused by unpredictable weather patterns and environmental changes that interfere with farming. These effects and potential remedies are examined in this article. Droughts and floods are examples of unpredictable weather that throws off crop cycles and farming schedules, resulting in lower yields and more uncertainty for farmers. The quality of the soil is reduced by rising temperatures and changing rainfall patterns, which makes the soil less productive and more prone to erosion. Agricultural productivity is negatively impacted by pests and diseases, which are more likely to spread in warmer climates. Food shortages are partly caused by reduced crop yields resulting from the combined effects of pests, degraded soil, and unfavorable weather. Food prices rise as a result of decreased supply, making it difficult for many people to afford basic essentials. A food shortage may...

Recycling as an Educational Tool for Secondary School Students

Image
By Precious Best Integrating recycling education into the secondary school curricula offers a powerful opportunity to instill environmental stewardship, practical problem-solving skills, and community involvement in students. Engaging students in recycling projects helps understand the bigger consequences of waste management in all its dimensions of influence on the ecology, economy, and society, shaping habits and values at the formative stage. Recycling education goes further than just sorting waste by teaching the need to conserve resources and be aware of the environmental consequences of waste, such as pollution and habitat destruction. Practical skills, such as identifying recycling materials and recycling symbols, acquired through such projects, make it possible for students to apply their knowledge in real-life situations. Involvement of the community in such projects teaches students the key issue of collective action and responsibility toward their local environment. Successf...

UPCYCLING vs. RECYCLING: WHICH IS MORE SUSTAINABLE?

Image
By Best Precious   We all wish to play our role in reducing waste and rescuing the environment, yet when it comes to recycling or upcycling, which of them actually has a greater impact? Let’s get it cleared in the open in simple words. Recycling: Breaking Down Things to Start Over You’re aware of the fact that we toss plastic containers, paper, and glass in the recycling basket, expecting they will turn into something new. That’s the general idea with recycling, essentially killing them off and purifying them into different materials. It takes a substantial amount of water and energy just to recycle things. And products like plastic disintegrate from each recycling, so they’ll never last forever. The Pros of Recycling ✔ Saves natural resources ✔ Prevents a lot of waste from going into landfills ✔ Reduces the need for fresh materials The Downside to Recycling ✖ Can be energy intensive ✖ Not everything can be recycled after all (unfortunate as it is) ✖ Some products (plastic, e.g.) w...

THE IMPACT OF IMPROPER WASTE DISPOSAL ON PUBLIC HEALTH

Image
By Ruth Oshuwa Irimonre Have you ever passed by a pile of trash and felt disgusted and concerned? Perhaps it is the smell, the flies hovering around, or what that pile may be doing to the environment-and to us. I have those moments, and it always leaves me wondering why proper waste disposal seems like such a big challenge. But the truth is, the impacts of not properly handling our waste go a bit deeper than just making our surroundings unpleasant; it threatens our health in ways many of us really don’t realize. Think about it: when waste isn’t disposed of correctly, it becomes a breeding ground for diseases. Have you noticed how stagnant water from discarded plastics becomes a haven for mosquitoes? Those are the mosquitoes that give diseases like malaria and dengue fever, which take away lives yearly, especially in developing countries. And then, of course, there is the open burning of waste in almost every neighborhood. While the act may be seen as a quick way out, the smoke emitted ...
