In this paper, potential of beneficial products recovery was investigated from plastic medical waste (PMW) by pyrolysis process. Disposable plastic is one of the chief items in the medical waste. High density polyethylene and Polypropylene is the main component of several PMW. These plastics have a higher latent as hydrocarbons sources for chemical industry. Pyrolysis of PMW was accomplished at a temperature range of 200-300 °C in a batch reactor make up of stainless steel. The chemical and physical properties of the pyrolysis liquid were much closer to the commercial fuel like diesel, petrol etc. The density is 840 kg/m3, the gross calorific value is 4.13•10 4 kJ/kg flash point is 39 °C in produces pyrolytic oil. This liquid can be used as alternative sources of fuel.

The present work is an effort to produce liquid fuel oil from plastic based medical wastes through thermal cracking process under oxidizing conditions. The mixed plastics from medical wastes were considered as a feedstock, shredded into small pieces and heated at 773 ± 10 K for 40 min with a heating rate of 20 K/min in a batch reactor for thermal cracking process. The feedstock was characterized by proximate and ultimate analysis along with thermogravimetric investigation. Moreover, chemical compositions of the liquid fuel oil were examined by FTIR and GC–MS spectroscopy. The properties of liquid product were also examined and compared to the commercial fuel oil. The average yield of brownish and sticky liquid fuel was obtained to be 52 wt% and the gross calorific value of the liquid was found 41.32 MJ/kg which is comparable to that of commercial diesel. FTIR spectrum showed characteristic absorption bands of C–H and =CH2 groups indicating presence of alkane and alkene compounds. GC–MS study demonstrated the chemical constituents of the liquid product that is mostly aliphatic compounds of mainly alkanes (16.28%), alkenes (10.67%), alcohols (14.65%) and ester groups (10.38%) including iso-phthalate (40.02%) as a predominant product. This experiment concludes that the liquid oil derived from thermal cracking of mixed plastics comprised of a composite mixture of organic components. A significant amount of non-degraded constituents like plasticizers, precursors, etc. remained in the product having some economic values with human health and environmental impacts during burning has been addressed in the current issue.

Health care institutions (HCIs) generate waste which can causes various injuries and infections to the patients, healthcare workers and also causes harm to the surrounding environment. Medical waste management (MWM) is vital for safe town development and the misconduct of medical waste may be a significant risk factor for the infectious diseases diffusion on our environment. The study carried out on 22 HCIs included public hospital, diagnostic centers, private hospitals and clinic in Jessore town of Bangladesh. This present study focused on the existing management structure, generation rate and difficulties of MWM. An inadequate number of HCIs are following the MWM method over their self-management. The findings of this study exposed that around 3 ton of medical waste is produced per day that is about 5.56% of entire waste production in this town. Over on an ordinary 0.98kg/day/bed medical waste that covering 10.89% infectious, 15.82% plastic, 3.46% sharp, 3.87% pathological, 60.94% domestic and 5.52% pharmaceutical waste were generated in this town.
