In the present work, the pyrolysis of polypropylene and polyethylene was evaluated with and without the addition of niobium oxide as catalyst by means of thermogravimetric analysis and experiments in a glass reactor. The results revealed that niobium oxide performed well in the pyrolysis of both polypropylene and polyethylene separately. For the mixture of polypropylene with polyethylene, the catalyst reduced the pyrolysis time.

Waste is generated by various day to day human activities. Adopting improper waste handling and disposal methods can harm the well-being of public and environment. Waste management creates new opportunities for entrepreneurs in terms of social causes and it affects the economic structure and economic status of any country. One of the new approaches in waste management and income generation is Social entrepreneurship. But in Bharat i.e. India the young entrepreneurs have a dearth of consciousness towards social entrepreneurship. This paper discusses the status of solid waste management in India and Government initiatives for managing Solid Waste at Dharamshala. The main objectives of study are 1) to check awareness of people in managing solid waste at Dharamsala 2) and how to convert the plastic waste into theme based parks as skilled initiative for entrepreneurs at tourist spots in Himachal Pradesh. The paper thus explores the scope for entrepreneurs in waste management. The study reveals that Solid waste management concept attracted the attention of government around 1970s. But till now we believe in filling the waste in the ground or putting them in the dustbin. Government of India has created few acts and rules on waste management which are listed in this paper. Through this study it is revealed that people of Dharamshala welcome to the construction of themed parks made from plastic bottles. Majority of these people believe in separating waste at home and according to them conditions of waste disposal at Dharamshala are not very good. There is a positive correlation between people’s opinion of constructing theme parks and using plastic bottles in park’s construction. Study believes that the quantity of plastic waste in our country is endless which creates lot scope and opportunity to the social entrepreneurs.

Sustainable development is among the foremost ideas that guide societal aspirations around the world. This book interrogates the concept through a critical lens, examining both its history and the trajectory of its manifestations in the Brazilian Amazon. The book argues that sustainable development is a concept that is better understood as involving embroilments and ongoing processes of contestation rather than a single end goal. The research offers historical analysis of Amazonian development from the colonial era into the discourse and praxis of sustainable development in contemporary times, and then illustrates the tensions of sustainable development plans that are experienced by people living in the areas geographically the closest to where those plans are being implemented. The history of the Brazilian Amazon is introduced to readers through focused discussions on the tensions between making grand plans for the region and the everyday practices and experiences of sustainable development, which involve considerably more muddling. Case studies explore agrarian reform initiatives that occur alongside road paving projects, the creation of extractive reserves and conservation areas that follow in the wake of assassinations, and the construction of a massive hydroelectric dam. While Amazonian sustainable development is a widely-accepted imperative, the research presented here shows how land use and infrastructure plans conducted in the name of sustainable development often perpetuate and reinforce economic and political inequalities.
