Biogas is the product of anaerobic vitiation of biodegradable matter. This paper focuses on the need of alternative and green sources of energy at a household level and how biogas produced from the everyday organic waste has the potential and possibility to replace LPG cylinders at houses, shops etc. and empower us to step towards an eco-friendly future. The purpose this small-scale experiment has been to find the perfect input matter that is easy to acquire and which produces the maximum amount of gas from minimum input and within small period of waste retention. Four different types of input waste material containing different quantities of cow dung and kitchen food waste were studied through individual experimental setups. Waste was mixed and kept at room temperature and the pH and total solid concentration of the samples were recorded on regular intervals. From the experiment it was found that the optimum yield of biogas at a small scale, based on the parameters such as retention period, pH and total solid con-centration can be obtained by the use of food waste form households and kitchens. The exact composition has been discussed in this paper. The energy generated by the small-scale generator has also been compared to that of an LPG cylinder and an LPG replacement model has also been presented.

Potential Value

This article offers insights into conceptual, pedagogical, and programmatic crossings and conflicts between the fields of Environmental Studies and Ethnic Studies. It highlights both the important intersections between the two fields and their potential value, while also addressing the challenges posed in the development of programmatic collaborations. Utilizing case studies drawn from the author’s own experiences, the article’s focus is on harnessing the strengths and limitations of both fields to promote transformative knowledge and action at multiple scales.
