Create a Biogas Plant Working Model in 3D using simple materials like bottles, saline pipes, and clay! This Inspire Award science project by Howtofunda explains the generation of biogas from organic waste through anaerobic digestion — a sustainable energy solution!

This model shows how kitchen waste or cow dung in an airtight container produces methane gas, which can be used for cooking and lighting in rural areas. A great way to understand renewable energy and waste-to-energy concepts.
