Introduction

As the global demand for clean and sustainable energy sources grows, alternative technologies that convert waste into energy are gaining prominence. One such promising approach is gasification, a thermochemical process that transforms carbon-based materials—such as biomass, coal, or municipal solid waste—into syngas, a versatile fuel composed mainly of carbon monoxide (CO), hydrogen (H? ), and carbon dioxide (CO? ). Unlike combustion or incineration, gasification occurs in a controlled oxygen environment, making it cleaner and more efficient. It offers potential solutions for energy generation, waste reduction, and even hydrogen production, aligning well with circular economy principles and climate goals. [

Gasification is a process that converts organic or fossil fuel based carbonaceous materials into synthetic gas (syngas) by reacting them at high temperatures (typically 700–1,200°C) with a controlled amount of oxygen and/or steam. Unlike full combustion, gasification doesn't involve burning the material entirely. Instead, the chemical reactions partially oxidize the feedstock, yielding a combustible gas mixture that can be used for: Power generation, Heat production, Chemical synthesis, Hydrogen recovery, Biofuels manufacturing.[

Removal of moisture from the feedstock using heat. Decomposition of organic material into char, tar, and volatile gases at high temperature in the absence of oxygen. A small amount of oxygen or air is introduced to partially burn the material, generating the heat needed for the rest of the process. The remaining carbon reacts with steam and carbon dioxide to produce syngas. Fixed Bed Gasifiers (Updraft or Downdraft): Simple design, commonly used for small-scale biomass conversion. Fluidized Bed Gasifiers: Efficient and flexible, ideal for a variety of feedstocks. Entrained Flow Gasifiers: High temperatures and pressures allow complete gasification, suitable for coal and industrial use. [8].

Converts waste that would otherwise go to landfills into usable energy. Produces fewer pollutants such as dioxins and furans. Works with coal, biomass, agricultural residues, and municipal solid waste. Syngas can be used directly or converted into electricity, fuels, or chemicals. More efficient than direct combustion and allows for carbon capture and storage (CCS).Using syngas in gas turbines or internal combustion engines. Converting syngas to methanol, ethanol, or diesel via Fischer–Tropsch synthesis. Extracting hydrogen from syngas for use in fuel cells or industrial processes. High-temperature applications in steel, cement, and glass industries. Initial investment and infrastructure costs are significant. Syngas needs to be cleaned before use, especially in chemical synthesis. Waste composition can affect efficiency and consistency. Often confused with incineration, which may raise environmental concerns. [9, 10].

conclusion

Gasification is a forward-looking technology that bridges the gap between waste management and clean energy production. By converting a wide range of materials into syngas, it supports energy diversification, reduces landfill dependence, and cuts greenhouse gas emissions. While there are technical and economic challenges to overcome, advances in gas cleaning, reactor design, and policy support can unlock the full potential of gasification in a sustainable, low-carbon future.
