“…In healthcare facilities where waste is segregated, it often gets mixed at the temporary storage site or during collection by transporting companies or waste collection service providers Debere et al, 2013;Sawalem et al, 2009). Appropriate segregation and resource recycling has been found to achieve a 15% reduction in the quantity of medical wastes (Sabour et al, 2007). This has economic implications for the health sector.…”

Increased awareness about inadequate management of solid medical waste (SMW) has led to increased independent surveys in African countries and yet published data remain scanty on the subject in Africa as compared to the rest of the world. To evaluate the overall compliance with World Health Organization (WHO)'s ten recommendations on SMW practices in Africa through a literature review, we conducted literature search using search terms as "medical waste OR clinical waste OR biomedical waste OR hospital waste OR healthcare waste OR hazardous waste AND Africa" in PubMed, African Journals Online, Web of Science, Proquest, Embase, Google scholar and Scopus. Additional articles were included from open google search. Articles were selected for inclusion if they described SMW management activities such as waste segregation, collection, transport (on-site and/or off-site), temporary storage, treatment and final disposal; were located in an African country and were written in English; or if written in a different language, had an English abstract with the relevant information. Evaluations were based on fifty eight (58) full text articles which were pooled together. The fifty eight (58) full text articles represented research undertaken in 20 countries. Overall, six countries (30%) broadly met half of the WHO's 10 recommendations. Based on the reviewed articles, the greatest compliance was shown with "daily collection of waste from the service areas" (100%). Areas of least compliance were "appropriate use of color codes" (18%) for labeling waste bins, "off-site conveyance" (16%) and "periodic training" (18%). In spite of growing awareness, SMW management in most African countries was sub-standard. Appropriate use of color codes, periodic training and off-site conveyance need to be addressed in terms of reporting and practice. Common challenges and unremarkable progress in SMW management in Africa raise a question about whether a unified approach should replace independent country efforts.

“…So the highest and lowest daily waste generation rate were 5.5±0.35 and 2.6±0.78 kg/available bed in H7 and H3 hospitals, respectively. Results of studies in different provinces, apart from confirming this issue, showed that the rate of waste generation per bed for the provinces of Semnan 3.6, Esfehan 3.14, Fars 3.30, Markazi 3.24, Yazd 3.45, Ardebil 3.53, Boushehr 3.8, Zanjan 2.92, Azarbayjan Gharbi 3.20, Guilan 3.16, Qom 2.87 (Sabour et al, 2007), Kashan 3.44 (Mostafaei et al, 2004), cities of Tehran 2.7 (Hassan et al, 2008), Babol 2.01 (Amooei, 2003), Shiraz 4.45 (Askarian et al, 2004b), Mashhad 1.67 (Sadeghi, 2001), Tabriz 3.48 (Taghipour and Mosaferi, 2009) and Yasoj 5.5 kg/day (Raigan Shirazi et al, 2008). In this study, total infectious wastes per capita were reported to be 2.3±0.39 kg/available bed/day, 3±0.5 kg/occupied bed/day and 5.2±0.84 kg/inpatient/day.…”

“…One of the major sources of waste generation are produced by various spectrum of health care providers especially hospitals (Sabour et al, 2007, Wong et al, 1994. Due to having pathogenic microbial factors, hazardous chemical and radioactive substances as well as sharp components, these materials are considered hazardous waste (Adegboye et al, 1994, Prüss et al, 1999.…”

The integrated hospital solid waste management emphasizes the need to conduct a survey based on a standardized method that equally be analyzed at national level. This study aimed to test the usability of a national tool to do integration data analysis of hospital waste management status. Then, a typical study was conducted in Karaj hospitals. Also, critical analysis of hospital's solid waste management aspects was done, and shortcomings in the aspects were identified. The pilot study results showed that the daily per capita waste generations were reported to be 4.2±0.49 kg/available bed, 5.8±0.63 kg/occupied bed, and 10.3±0.9 kg/inpatient. The names of the hospitals were omitted when they were named from H1 to H8. So the highest and lowest daily waste generation rate were 5.5±0.35 and 2.6±0.78 kg/available bed in H7 and H3 hospitals, respectively. In this study, total infectious wastes per capita were reported to be 2.3±0.39 kg/available bed/day, 3±0.5 kg/occupied bed/day and 5.2±0.84 kg/inpatient/day. Furthermore, the averages per capita of total general waste were 2±0.4 kg/available bed/day, 2.8±0.51 kg/occupied bed/day and 5.1±0.8 kg/inpatient/day. Analysis of the Karaj hospital waste management status showed statue of hospital waste management in 88% of hospitals were ranked moderate when others were achieved to be poor by 12%. The hospital waste management had been evaluated poor in term of collection, transportation and manpower aspects, moderate in the separation and temporary storage aspects and good in the disposal aspect. It was also found that the MOHME tool is appropriate tool to investigate the status of waste management in hospitals.

“…The hospital waste consists of a broad range of solid and liquid materials from clinic and laboratory from hospital or medical center [28]- [30]. The solid waste was suggested to be paper, food residue, textile, plastic, human body parts, diagnostic tissues, used needles and syringes, medical devices, and etc.…”

Abstract-In this paper, a review on applications of hydrothermal treatment (HTT) for upgrading waste materials was presented. This work was focused on pilot-scale HTT processes that applied to several kinds of waste for alternative solid biofuel production. The HTT utilizes subcritical water condition that has special properties as an organic solvent. With the temperature around 180-240 °C and the corresponding pressure that keeps the water in the liquid phase, many reactions are induced by the subcritical water such as hydrolysis and dehydration. The waste materials that had been subjected to the HTT processes by pilot-scale reactors such as paper sludge, antibiotic residue, and municipal solid waste were reviewed herein. Moreover, a novel application of HTT on hospital waste treatment has been carried out in a pilot-scale level. Results showed positive effects and consistency with the previous research works. Thus, the HTT showed possibility to be an option for pretreating waste materials prior to final conversion processes.Index Terms-Hydrothermal treatment, high moisture waste, pilot-scale hydrothermal, solid biofuel.
