Kumasi Technical University of Ghana (KsTU) was recently converted from a Polytechnic with the aim of providing higher education through teaching and research. It hopes to take advantage of this conversion to be known for the development of renewable energy and sustainable engineering in Ghana. This goal must align with the University’s day to day activities which require redefining its work-place environmental culture and developing new paradigms by creating sustainable systems on campus.
Even as it carries out its mandate as an institution of higher learning, KsTU must demonstrate to the public, staff, and students that it is responsible and willing to take the lead in creating a more sustainable tomorrow by testing systems and technologies, and to advance innovative solutions to national and global challenges. The university can manifest sustainability in two ways that should be complementary – curriculum and operations. In other words, we have the ability to manifest sustainability, not only in theory, but in practice in everyday operations on our campus.
Consequently, KsTU has recently established a Centre for applied research, technology development and training in Renewable Energy and Energy Efficiency through a grant won under Skills Development Fund (SDF). The Centre (known as CREK) undertakes applied research in areas of RE & EE and offers tailor-made vocational and technical training programmes to diverse groups of people including local artisans, as well as students and graduates from Technical and Vocational Education and Training (TVET) institutions. The mandate of the Centre is to provide long-term support to local (and Regional) businesses that deliver products and services related to renewable energy (RE) and energy efficiency (EE).
Also, the University is seeking to develop a niche in renewable energy and sustainable environmental engineering. The curricula of these two programmes are under development. A green campus will therefore be a practical demonstration of what the University will be teaching in theory.
Campus greening is a concept which stands for the efforts to establish environmentally sustainable practises in educational institutions the world over. Its goal is to diminish the impact of ecological footprints by implementing the principles of sustainability at every level of institutional functioning. Greening the campus includes doing away with wasteful inefficiencies and using conventional sources of energies for its daily power needs, correct disposal and handling of waste, purchase of environment friendly supplies, and effective recycling program.
The University is confronted with unique challenges as the campus has grown considerably over the past several years, growing from just 4,000 students, to over 10,000 students in recent times. The population is expected to increase further with the conversion from polytechnic to technical university. This growth has necessitated the expansion of the campus facilities and the construction of new buildings thereby increasing the energy demand and waste generation on campus.
The university presently consumes about 10 GWh of electricity annually. Paying of electricity bill has always been a major problem, inability to pay, sometimes results in the university being disconnected by the power company. Besides, the university also experiences frequent power outages due to unreliable supply from the national grid.
There is no data on the volume of waste generated on KsTU campus presently, however the indiscriminate disposal of waste around the campus and in lecture halls, hip of solid waste left unattended to for several days, inadequate, and inappropriate waste collection bin, are evident of waste management challenges on campus.
The main objective of this project is to establish a green campus concept at Kumasi Technical University. This is expected to reduce waste generation, enhance waste management, and reduce energy consumption and dependency on national grid.
The specific objectives are to:
Improve waste disposal, collection and management among students and staff of the university through the provision of waste bins, education, waste sorting, and waste reduction
Figure 1: Conceptualize Frame work of KsTU Green Campus
The project is expected to have four tangible outcomes as follows
Renewable energy systems installed to replace 20 % of conventional energy supply by 2021
Waste management systems implemented to reduce waste generation and enhance waste collection and reuse by 2021
The project is expected to have the following outputs after implementation:
Renewable Energy System
Compact Fluorescent Lamps (CFLs) retrofitted with Light Emitting Diodes (LEDs)
Solar water heaters installed for school cafeteria and guest house
Sustainable Waste Management Systems
Standard waste collection equipment procured. This includes paddle waste bins, skips, waste trucks, and wheel barrows.
Waste recycled into other useful products such as composite materials, paper, manure, etc.
This section outlines the specific activities needed to be carried out to achieve each expected project outcome.

Kumasi Technical University was established in 1954 as Kumasi Technical Institute (K. T. I. ) to offer craft courses. In 1963, the Institute was converted to a non-tertiary Polytechnic status under the Ghana Education Service to start offering, in addition, technician diploma and sub- professional courses.
