“…The untreated cake had some oil, which could have been digested to produce biogas. Deshpande et al (2012) studied the anaerobic degradation of mahua and hingan oil cakes [97]. Their investigation disclosed that both the seedcakes generated biogas in the scale of 198 to 233 l/kg of seedcake.…”

The circular economy is at the core of sustainable development. The generation of biogas from the massive quantity of agricultural waste biomass is one of the critical drivers of the circular economy. Biogas has enormous renewable energy potential and has multitudes of applications in today’s energy-intensive society. Oil cakes, a known Agri-waste, are the by-product of oil processing, and are rich in nutrients. The edible oil cakes mostly have been used as a cattle feed; however, non-edible oil cakes do not find many applications. Their production is continuously escalating as non-edible oils are increasingly used in biodiesel production. Recently, there is a lot of emphasis on biogas production from these oil cakes. This paper reviews in detail biogas production from both edible and non-edible oil cakes. Chemical composition and various other applications of the cakes are also reviewed in brief. The survey illustrates that multiple parameters such as inoculum sources, co-digestion and reactor design affect the biogas production. All those factors, along with biogas upgrading and the economy of the process, are reviewed. Finally, future research opportunities are suggested to improve the viability of the biogas production from oil cakes.

Madhuca longifolia var. latifolia belonging to the family Sapotaceae which was also known as Mahua and Butter tree. The present study was designed to identify the fatty acids present in oil and to analyze the elements present within the seed and seed cake. After extraction of oil, it was found that the seeds were high in oil content within the kernel. The oil percentage found in seed was highest recorded as 57.59%. In GCMS analysis of oil, the oleic acid which is monounsaturated fatty acid (45.11%) was recorded highest in amount compared to others. Elements within the seed and seed cake were analyzed using Energy Dispersive X-ray Spectroscopy. Concentrations of seven elements such as Calcium (35.53%), Carbon (33.56%), Oxygen (22.46%), Nitrogen (5.20%), Phosphorus (2.18%), Magnesium (0.23%) and Sodium (0.04%) had been determined in seed cake by Energy Dispersive X-ray Spectroscopy. The present study provides information about the availability of some essential minerals and fatty acids, which can be used as nutraceuticals and it may also help in developing the biofuel for industrial purposes.

“…HDI remains low until energy consumption reaches 468 kgoe per capita, then with energy consumption 487 kgoe and above, HDI upgrades to medium human development. For India, it may be said that the country needs at least 500 kgoe per capita energy consumption to remain in the medium human development group 10 . Although several attempts have been made to establish a relationship between energy consumption and HDI, and electricity consumption and HDI, studies that examine the relationship between access to modern energy and HDI are few and far between.…”

Social constructs of energy poverty and the resulting capability deprivations in rural India

This PhD project studies energy poverty in rural India in order to understand its underlying social constructs and effect on people's well-being. A core inspiration for undertaking this research stems from my profound interest in understanding the way in which people's energy demands, energy sources, and services interact with their social systems, such as their day-today routines, established norms, well-accepted traditions, and culture. In so doing, this project aims to contribute towards achieving India's goal to universalise modern energy access to all. Presently, India suffers from longstanding energy poverty, with about 239 million people unconnected to electricity and about 800 million relying on harmful solid fuels for cooking. This study has three objectives: (1) to understand the links between people's livelihood practices and household decisions in relation to energy sources and services; (2) to understand how the energy poor's capabilities are influenced by their choice of energy sources; and (3) to understand the role that social structure has on persistent energy poverty and find out ways to break the energy poverty cycle. This project represents a niche of studies that investigate energy poverty from an undervalued realm of social science. It benefits from an emerging conceptualisation that strongly argues for a research lens that navigates beyond the economic and technological influences of energy systems and unpack the relationship between energy and society. This novel concept acknowledges that demand for energy is not for energy itself, but for undertaking services required by people as members of society. Energy, therefore, is intricately intertwined with social systems that shape people's needs, choices, decisions, and opportunities. To unpack this complex connection between energy and society, this project applies two prominent social theories: the Capability Approach (CA) and Structuration Theory. This research employs a qualitative approach of inquiry. Techniques applied for data collection comprise a set of in-depth interviews, focus group discussions, and observation. These techniques provide valuable groundwork for gathering a subjective understanding of people's life experiences, both individual and collective, values, societal dominations, and energy practices. Fieldwork for the study was undertaken in the Chittoor district in the state of Andhra Pradesh, India.
