Simple onsite biodegradable biodigesters are innovative systems that are revolutionizing the way we handle waste in Ghana. They transform solid waste into valuable resources using the anaerobic digestion process.

Biodigester’s solid waste treatment process involves several key components working together:
- Anaerobic Digestion: The core process relies on anaerobic digestion, where microorganisms break down organic matter in the absence of oxygen. This natural composting method effectively treats all biodegradable materials within the biodigester.
- Separation: As flushed water and solid waste enter the biodigester, the system immediately separates solids from liquids. This ensures efficient processing of different waste components.
- Biological Filtration: The biodigester utilizes a biological filter composed of fiber, black soil, and sometimes porous concrete. This filter fosters the growth of bacteria and other organisms crucial for biodegrading the solid waste.
- Decomposition and Conversion: Through the biological filter and anaerobic digestion, solid waste, including toilet paper and degradable cleaning materials, decomposes and converts into safe, nutrient-rich soil suitable for disposal.
- Harvesting: After a period of continued usage, depending on lifestyle and soil type, the accumulated solid waste transforms into a usable compost. You can safely remove this compost, also known as manure, and use it for agricultural purposes, providing a sustainable approach to waste management and completing the sanitation process.
