Waste management is, unfortunately, a global challenge that demands innovative and sustainable waste consulting solutions. Though the entire world grapples with increasing waste production, underdeveloped areas struggle the most. It is becoming crucial to explore alternative methods to not only reduce waste but also harness its potential as a valuable resource. Today, we will briefly touch on some waste-to-energy (WtE) methods, particularly focusing on its potential benefits for under-developed areas like some African countries. But first, what is waste-to-energy?

What Is Waste-to-Energy?

Simply put, waste-to-energy initiatives are those that seek to convert unusable products into usable energy – thereby turning something useless into something useful. These “unusable products” may include:

  • Consumer trash (plastic, paper, metals)
  • Human wastewater
  • Agricultural byproducts (crop residue, forest residue, organic waste)

The output of energy may also come in several forms, such as electrical energy or nutrient-rich compost for plant energy. We’ll take a look at these next.

A Few Valid Waste-to-Energy Processes

#1: Biomass Conversion

One promising avenue for converting waste into energy is through biomass conversion. Biomass refers to organic materials derived from plants and animals, including crop residues, forestry residues, and even organic waste such as food scraps and agricultural byproducts. Through anaerobic digestion or thermal processes like combustion and gasification, biomass can be transformed into various forms of energy, including biogas, biofuels, and heat.

By implementing biomass conversion technologies, under-developed areas can reduce waste, alleviate pressure on traditional fuel sources, and mitigate environmental pollution. You can read more about this process here: Biomass explained – U.S. Energy Information Administration (EIA).

#2: Waste-to-Energy Incineration

This method involves the controlled combustion of waste materials, generating heat that is then used to produce steam and drive turbines to generate electricity. By adopting advanced incineration technologies such as fluidized bed and gasification, WtE plants can achieve higher energy efficiency and minimize environmental impacts.

In the context of underdeveloped regions, where waste management infrastructure is often lacking, WtE incineration can provide a dual advantage:

  1. Reduce the volume of waste
    • Mitigates the burden on landfills
    • Minimizes health hazards associated with uncontrolled waste disposal
  2. Minimize electricity shortages
    • Provides a reliable and sustainable source of power to underserved communities

#3: Solar-Powered Waste Treatment

Solar energy also holds immense potential for revolutionizing waste management practices, particularly in regions with abundant sunlight. Solar-powered waste treatment systems leverage the sun’s energy to power various waste treatment processes, such as sterilization, composting, and drying. These systems can be deployed for different types of waste, including human waste, agricultural residues, and organic waste.

The advantages are numerous, however, setting up this infrastructure can be expensive and involved. For many reasons, the barrier to entry for this method is great. Once established, though, this WtE process is infinitely sustainable, with no need for outside inputs aside from repairs.
