The need to manage construction and demolition waste (CDW) has led to environmentally-friendly actions that promote the reuse and recycling of this type of waste. In the last two decades, a variety of recycling methods for construction and demolition wastes (CDW) have been developed.It is estimated that the construction industry in India generates about 10-12 million tons of waste annually. Projections for building material requirement of the housing sector indicate a shortage of aggregates to the extent of about 55,000 million cu.m. An additional 750 million cu.m. aggregates would be required for achieving the targets of the road sector. Recycling of aggregate material from construction and demolition waste may reduce the demand-supply gap in both these sectors. The scarcity in the availability of aggregate for the production of concrete is one of the important problems facing b...

A sustainable campus integrates the technical knowledge of all specializations to develop policies that reduce the impact on the environment, by providing awareness to the students about existing environmental concerns and encourages research for sustainable utilization of the resources in the campus. The study area discussed in this paper is Jaypee University of Engineering & Technology (JUET), existing on Agra-Mumbai national highway, Guna district, M.P, in an area of 125 acres, housing more than 2000 students inside the campus. The present work comprises the study of existing polices in the university related to land use pattern, construction, water management, energy efficiency and waste management; for estimating the sustainable options to reduce environmental foot print. The study has identified three areas which can effectively contribute to environmental sustainability i.e. utilization of renewable resources, effective rainwater harvesting and recycling of the solid waste generated in the campus. The results suggested that study area has good potential for rainwater harvesting, harnessing the solar energy and production of bio gas from kitchen waste generated in the campus.

environmental concerns and rising support from the nations to conserve the planet. Particularly for a country
like India, this approach is highly relevant for combating the increasing stress on different sectors of the
society due to the growing population. Solid waste management is an important sector that requires an
immediate attention in the current context. Implementation of integrated sustainable waste management
approach minimizes the waste and provides economic benefits, through best suitable method for managing
the waste. In the present scenario, it is difficult for local bodies to apply this approach throughout the country
due to diverse conditions and financial constraints. However this approach can be implemented through
decentralization of solid waste management by the local bodies at a small scale. Technical institutes have
a greater role to play in the society by nurturing the young minds about the need and ways to develop a
sustainable society. The paper aims to discuss these issues.
Design/methodology/approach – The study area discussed in this paper is Jaypee University of
Engineering and Technology situated on Agra-Mumbai national highway, Guna district, Madhya Pradesh,
India. It covers an area of 125 acres and houses a population more than 3,000. The present work discusses
about the development of strategic plan for sustainable waste management on the campus through the
characterization and analysis of waste samples collected from academic buildings, hostels, mess, shopping
complex and residential areas for beneficial utilization.
Findings – The study revealed that potential benefits such as biogas generation from organic waste,
resource optimization through 3R concept (reduce, reuse and recycle) from paper, plastics, cardboard, glass,
metals, etc. could be derived by adopting suitable waste management strategy.
Originality/value – The present work discusses the feasible options for the efficient utilization of the
components of solid waste through integrated solid waste management system. The university with its
diverse nature of wastes generated from academic buildings, hostels, mess, shopping complex and residential
areas; provides a good opportunity to understand the options for sustainable waste management on the
campus for wider applications.

for the reduction in energy consumption is critical for the development of a sustainable campus. Such
centralized organizations along with their dense populations constituting young students and experts
from various specializations serve as ideal sites for application of sustainable development principles.
These principles integrate the technical knowledge of all specializations to increase the efficiency of
built infrastructure and promote conservation practices thereby reducing environmental impacts. The
study area discussed in this paper is Jaypee University of Engineering & Technology (JUET), housing
more than 2500 students inside its campus spread over an expanse of 125 acres off the Agra- Bombay national highway in Guna district, M.P. The study area has most favourable conditions like
larger number of sunny days and higher day temperatures (above 300 C) for most part of the year.
The present work discusses about the existing scenario of energy utilization in campus and the
options for harnessing solar energy as a replacement in a view of enhancing energy conservation.
The areas of application considered in this paper are water heating, water pumping, outdoor lighting
and cooking using solar photovoltaic modules and concentric collectors. The paper also discusses
about the options and areas for optimization of energy utilization in the campus through energy
efficient devices. Development of such management plan provides both economical savings and
ecological benefits. The results suggested that the study area has a good potential for harnessing
solar energy, which could result in considerable savings on energy expenditure in the long run.
Keywords: solar energy, energy management, sustainable campus and photo voltaic modules.
