As far as purchasing equipment for the institution or its particular programmes is concerned, it is best to start off with thorough planning. We describe this process extensively in the PRODUCTION: MATERIALS area. Initially, it is good to begin with 3R – reduce, reuse, recycle – and add ‘repair’ as well. It is important to factor in the criteria of running costs, profitability, and disposal costs of new appliances which we decide to purchase after all. This could be associated with bigger initial investment but increased longevity of the equipment, which is also important. This theme is developed in the texts related to BUILDING AND INFRASTRUCTURE and EVERYDAY PRACTICES.
