“…On the other hand, medical waste management in Jordan, Syria, and Turkey still needs major improvement [19][20][21]. In general, the current situation of waste management in almost all the Middle East is characterized by insufficient jurisdiction, lack of control, and technical and financial resources [22].…”

There is a lack of information about medical waste management in Iraq. This study aims to monitor and evaluate the current situation of medical waste management in Baghdad as it represents the capital and the biggest populated city in Iraq. About 32% of hospitals are located in Baghdad. Ten state-owned hospitals in Baghdad with the biggest bed capacity were investigated. The study used structured interviews with staff in charge of waste management in the sampled hospitals to collect data. The results showed that the generation rate of medical waste in the ten hospitals was 0.5 kg/(bed•day). The study also found that there were insufficient, ineffective, and improper isolation, collection, storing, processing, and safe disposal of medical wastes in the sampled public hospitals of Baghdad. The study recommended that the Iraqi Ministry of Health takes extensive and quick effective measures to better monitor and evaluate medical waste management and provide ongoing training to personnel responsible for waste management in the hospitals.

Palestine has considerable potential for bioenergy production, which can contribute to the independence of the nation's energy sector. However, few projects have been implemented for the production and utilization of bioenergy. In this study, the potential effects of using bioenergy from various sources, such as municipal solid waste, wastewater treatment plants, and animal farms are studied. Certain studies and successful projects in Palestine are evaluated. Different technologies that could be used effectively are introduced. The challenges facing the adoption of bioenergy are discussed. The effect of energy generation is studied, and an economic analysis is performed. Results show that if bioenergy is adopted in the cities of Palestine, then approximately 19% of the total energy demand can be covered. Based on successful, established projects, Palestine has promising potential to generate low‐cost energy from bioresources. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Therefore, increasing public pressure, as well as the consequent environmental legislation, has driven stakeholders, decision makers and experts to introduce stronger waste management strategies [2]. These strategies are intended not only to deal with the environmental and socioeconomic conditions of the affected countries, but also to ensure the efficient recovery of significant volumes of biowaste [3], [4]. In recent years, biological treatments have come to be considered to be one of the most suitable options for handling organic residues.…”

Nowadays, Tunisia faces challenging environmental and energy issues which relate mainly to the implementation of an appropriate solid waste management system capable of dealing with the high production of biowaste on the one hand, and the increased need for water and energy resources on the other. Therefore, the current study is intended to develop a closed cycle technical concept treating mainly food waste (FW) through combined biological processes. In this approach, FW anaerobic digestion (AD) was destined to provide a valuable input material for FW in vessel-composting by exploiting the produced digestates. To this end, the gathered AD-effluents of three systems (D1, D2, D3) were entirely analyzed to select, as a further step, the most suitable one to be subject of the suggested post-treatment. Hence, several physiochemical parameters were examined as key performance indicators. It mainly consisted of moisture content, pH, C:N ratio and heavy metals contents. The current findings depicted that the generated digestates were characterized by a high moisture content which inspired its utilization as an unconventional moisturizing agent (MA) aiming to reduce the fresh water consumption during the composting process. Thus, two experimental setups were carried out to evaluate the effect of the selected digestate on FW-in-vessel composting process performance, as a non-standard MA inserted to A2, comparing to the unamended one (A1) which was moistened by fresh water. In fact, basing on the above-mentioned criteria, the relatively high C:N ratio (of around 15), as well as the relatively significant rate of the required macro- and micro-nutrients promoted the exploitation of biochar-rich digestate (D3) as not only an efficient unconventional MA, but also as a composting process booster. Furthermore, the results revealed that the addition of D3 improved significantly the composting process performance in terms of steering parameters including the attained temperature, MC and pH. When it comes to the maturity and stability assessment, the decreased profiles of C:N ratio, the nitrification index (NI), as well as the respiration activity (AT4) ascertained the fulfilment of the required conditions for both A1 and A2 to produce stable and mature end-products. However, regarding the compost quality, the examined concentrations of heavy metals met the requirement set by German standards and attested that both A1 and A2 generated highly-qualified products, rated as class B and A, respectively. Furthermore, it is noteworthy to mention that even the AD-effluents which were classified as an “inappropriate substrate” to be inserted to the composters, met the required criteria to be applied directly to land as a highly-qualified liquid biofertilizer. This latter ascertained, additionally, the efficiency and feasibility of the suggested closed cycle for a sustainable FW management. Graphic Abstract
