Hospital waste is categorized as a very dangerous waste type as it possesses many pathogenic elements and it can cause harmful human health effects. This research shows the survey and field investigation conducted at government hospitals located in Faisalabad. The quantitative waste analysis showed that 55% non-infectious, 15% infectious, 25% bio-hazardous, 2% sharps and 3% chemical waste is generation in these hospitals. Few main hospitals have their own incinerator but still either they are not working efficiency or insufficient to handle waste. However, this paper deals with the design of incinerator for small scale hospitals. The proposed incinerator has three chambers: primary chamber (temperature range 500-7000c), secondary chamber (temperature range 700-900oc), and tertiary chamber (temperature range 900-12000c). Situation analysis confirmed the earlier view that a hospital waste management project should be implemented at this hospital and an intensive training programmed, at all levels, and is required to deal effectively with this problem.

The rapid growth of population and development of industrial field is contributing to massive waste pollution in which plastic waste is considered as most difficult waste to deal with due to its non-biodegradable nature. This lead to various impact on environment as well as all living things. Many of the waste produced due to human activity will remain in the environment for long period of time leading to various environmental problem. To overcome this problem a study is conducted in which plastic waste is effectively utilized with bitumen a binding material in construction of flexible pavements to enhance its stability and water resistant capacity. Cleaned plastic waste is shredded to a size of 2.76mm-4mm is mixed with hot bitumen mix and then this waste plastic added bitumen is mixed with hot aggregate and the end product is used as laying material for road construction. The objective of this study is to give an innovative idea for effective use of plastic waste and recommend a favorable percentage of plastic for replacement of bitumen. This paper also includes some tests performed on aggregate and bitumen.
