HIGHLIGHTS

  • Present hospital waste management system of Khulna city was studied.
  • Waste generation rate was determined by survey from six selected hospitals.
  • Hospital wastes were classified according to their characteristics.
  • Role of different organizations in hospital waste management was observed.
  • A new flow path is proposed for improving the management system of hospital waste.

ABSTRACT

Generally, hospital wastes are highly harmful and infectious in nature. Management of hospital waste is a crucial need for most of the cities in the world. In Khulna city of Bangladesh hospital waste management (HWM)   system had been focused on collection and dumping only. The present improper management of hospital waste in Khulna city may play a vital role for contamination of nearby communities and spread the occurrence of skin diseases, asthma, diarrhea, allergy, eye irritation, etc. The aim of this study was to investigate the existing HWM system and determine the hospital generation rate according to different categories in Khulna city. The study was carried out in six hospitals that produce major portion of medical waste in the city. For this reason, a questionnaire survey was conducted to observe the existing management system, generation rate and type from the hospital authority. Field survey was conducted to categorize and measure the generated waste by weight machine directly to compare with the data from questionnaire survey. The study revealed that the average generation rate of different categories of hospital waste such as general waste, anatomic waste, pathological waste, chemical waste, pharmaceutical waste, infectious waste, sharp waste and liquid waste were 0.138, 0.0028, 0.0091, 0.0036, 0.0009, 0.0334, 0.036 and 0.0205 kg/day/bed, respectively. The study showed that there was no radioactive waste in the selected hospitals of Khulna. Improper segregation, lack of treatment, consciousness and financial support are liable for inappropriate management. Finally, a management system was proposed including proper segregation and storage by selected colored container, proper collection, safe transportation, proper treatment and disposal for improving existing system. Regular monitoring and assessment of hospital waste by hospital and city authority will also be needed for a safe and healthy environment.

Roadside urination and public sanitation facilities in Dhaka, Bangladesh

Roadside urination and public sanitation facilities in Dhaka, Bangladesh

M. M. Hasan*, K. Basak, K. Rayhan

HIGHLIGHTS

  • Roadside urination is a very common incident that impacts on both environment and public health.
  • A randomized face to face field survey was conducted at different spots.
  • Rickshaw puller is the main group who urinate at roadside.
  • People are necessitated to urinate at roadside due to insufficiency of public sanitation facilities.
  • Roadside urination is one of the crucial barriers for improving the sanitation situation of the city.

ABSTRACT

Mass migration, uncontrolled population growths, unplanned urbanization and lack of proper sanitation facilities (i.e. public/mobile toilets) are accelerating roadside urination in Dhaka city which impacts on society, environment and public health. As such this research focused very first time on this unhygienic but frequent incident of the city. Randomized face to face field survey was conducted at different roadside urination spots and public toilet locations in Dhaka South City Corporation (DSCC). Four different questionnaire forms were prepared to cover four different groups of people. The survey covered total 364 people. Among ten different professions of urinators rickshaw puller was the main group who urinate at roadside. Majority percentages (80%) of people were found aware of this unacceptable practice but they were bound to urinate at roadside due to intense insufficiency of public sanitation facilities. Lack of law enforcement was also accountable for remaining this problem. Nearly half of the users were unsatisfied about the hygienic conditions of the existing public toilets. More than 70% of people relied on the effectiveness of privatization of this sector. The findings revealed that the frequent incident of roadside urination is one of the major barriers for improving overall sanitation practice of the city.

Analysis of road safety related data from a key section of a highway in Bangladesh

Analysis of road safety related data from a key section of a highway in Bangladesh

S.M.S. Mahmud1,2,*, Luis Ferreira1, M.S. Hoque3, A. Tavassoli1, N. Islam3

HIGHLIGHTS

  • Road safety problems of Jamuna Bridge and its approach roads are investigated.
  • Traffic operational and behavioural characteristics are analyzed.
  • Hazardous Road Locations (HRL) are identified.
  • Measures for improving the likelihood of accidents are suggested.
  • Application of surrogate safety measures as an alternative analysis approach is proposed.

ABSTRACT

According to recent statistics, more than 150 accidents and 440 casualties are happening per year on the 39 km road section of Jamuna Bridge and its approach roads, a major highway section in Bangladesh. Such statistics demand special attention for analysis, investigation, and treatment. This study presents the results of a comprehensive study on the safety problems of that highway section. The study used a special dataset recorded by the road operator for accident analysis and characteristics evaluation. Different aspects of traffic operational and behavioural characteristics are also discussed using onsite observational survey and video analysis. The analysis shows that the accidents are highly clustered at a few sites with the significant involvement of heavy vehicles, particularly trucks and buses. A total of 15 such locations are identified and considered to be hazardous. It is expected that the outcome of this research will be helpful not only to improve the safety aspects of the study section; but also to understand the way of accidents happening at the high standard roadway facilities. The application of the new analyses approaches will be useful in identifying cost-effective safety measures relating to the aspects of the road environment and driver behaviour, thereby reducing the likelihood of accidents.

Thought on suitable material to assist empty fruit bunch composting

Thought on suitable material to assist empty fruit bunch composting

A.Y. Zahrim

Palm oil mill industry is among major agricultural industry in Malaysia. However, the palm oil mills generate large amounts of empty fruit bunches (EFB). Production of 1 tonne of crude palm oil could generate 0.8 tonne EFB. Composting is regarded as a sustainable technology for processing EFB. Composting is a controlled biological process that can accelerate the conversion of EFB to humic substances like product known as compost. The compost can be applied as a soil amendment or mulching. The quality of compost depends on the raw material, process system i.e. reactor or non-reactor, process parameter i.e. carbon to nitrogen ratio (C/N), moisture, turning frequency, etc.as well as weather/season. Due to inexpensive capital cost, windrow (non-reactor system) is chosen by the composter to operate the composting process…
