Abstract In recent years, microbiological treatment to remediate contamination by heavy metals has aroused public attention as such pollution has seriously threatens ecosystems and human health and impedes sustainable development. However, the aspect of actual industrial wastewater and solid waste remediation by microorganisms is not explored sufficiently. And what we focus on is technical field of microbial remediation. Therefore, in this review, we discuss and summarize heavy metal treatment via microbiological approaches in different media, including wastewater, solid waste from industrial factories and polluted sites. We also clarify the technical applicability from the perspective of biosorption, bioleaching, biominerization, etc. In particular, the exploration of the combination of microbiological approaches with chemical methods or phytoextraction are scrutinized in this review relative to real waste heavy metal remediation. Furthermore, we highlight the importance of hyperaccumulator endophytes. Graphical abstract

The environmental data (carbon emissions, industrial wastewater discharge, exhaust gases emissions and solid waste production.) and economic data (Per Capita GDP) from 1985 to 2010 was selected to fit environmental Kuznets curve (EKC). The results showed that all the EKC models were significantly fitted (p<0.01), the EKC shapes of Per Capita GDP (PCGDP) between carbon emissions, industrial exhaust gases emissions, and industrial solid waste production were inverted-U shape, respectively. The EKC shape of PCGDP and industrial wastewater was inverted-N shape. This study suggested that Henan Province is still at the stage of industrial development, and EKC turning points of carbon emissions, industrial exhaust gases, and industrial solid waste production have not been reached. Therefore, it is necessary to optimize and adjust energy-depended industry structure to improve environment quality and welcome EKC turning points coming as soon as possible.

Microbial Action

Solid waste management is a huge environmental threat not just in context to Indian Scenario, but globally as well. It is reported that on average around 1.5 lakh tones of solid waste is generated per day in India of which only 20% is treated and managed safely, the rest is dumped on land or burnt both which are highly toxic to human and animal health. At several waste processing sites in India, the fresh mixed waste received each day, is first manually separated to remove plastics and other non-biodegradable contents, this exposes the laborers to a very unhygienic working conditions and exposes them to deadly microbes and stench.. In the present work, we have developed an ingenious way which handles mixed waste with minimal manual intervention and protects the health of laborers while generating good quality manure. The mixed waste is directly fed in to the bio bins where due to microbial action, the biodegradable components are composted, the treated waste is then separated in to compost and non-biodegradable components using a bench top trommel. It was found that Bioinoculum combined with cow dung quickly achieved the compost of mixed organic waste with minimal maintenance in contrast to vermi-composting. From this study, it is observed that the mixed municipality waste could be treated and managed effectively, safeguarding the health of laborers and the generated compost is of good quality which can be used for crop cultivation or gardening

This study was performed to evaluate the efficiency of tapioca processing wastewater treatment using aerobic biofilter with variety of biofilter media: coir, coal, PVC plastic and Bio - Ball BB15 plastic. Research results in the lab demonstrated all four aerobic biofilter models processed can treated completely N and COD which COD reached 90-98% and N reached 61-92%, respectively, at the organic loading rates in range of 0.5, 1, 1.5 and 2 kgCOD/m3.day. The results identified coir filter was the best in four researched materials with removal COD and specific substract utilization rate can reach 98%, and 0.6 kg COD/kgVSS.day. Research results open the new prospects for the application of the cheap materials, available for wastewater treatment.

The increasing volume and complexity of waste associated with the modern economy as due to the ranging population, is posing a serious risk to ecosystems and human health. Every year, an estimated 11.2 billion tonnes of solid waste is collected worldwide and decay of the organic proportion of solid waste is contributing about 5 per cent of global greenhouse gas emissions (UNEP). Poor waste management - ranging from non-existing collection systems to ineffective disposal causes air pollution, water and soil contamination. Open and unsanitary landfills contribute to contamination of drinking water and can cause infection and transmit diseases. The dispersal of debris pollutes ecosystems and dangerous substances from waste or garbage puts a strain on the health of urban dwellers and the environment. India, being second most populated country of the world that too with the lesser land area comparatively, faces major environmental challenges associated with waste generation and inadequate waste collection, transport, treatment and disposal. Population explosion, coupled with improved life style of people, results in increased generation of solid wastes in urban as well as rural areas of the country. The challenges and barriers are significant, but so are the opportunities. A priority is to move from reliance on waste dumps that offer no environmental protection, to waste management systems that retain useful resources within the economy [2]. Waste segregation at source and use of specialized waste processing facilities to separate recyclable materials has a key role. Disposal of residual waste after extraction of material resources needs engineered landfill sites and/or investment in waste-to-energy facilities. This study focusses on the minimization of the waste and gives the brief about the various initiations for proper waste management system. Hence moving towards the alternatives is the way to deal with these basic problems. This paper outlines various advances in the area of waste management. It focuses on current practices related to waste management initiatives taken by India. The purpose of this article put a light on various initiatives in the country and locates the scope for improvement in the management of waste which will also clean up the unemployment.

<p>Hospital X was class b private hospitals that are located in Batam with 297 unit beds. The waste that can be categorized as solid waste medical in the hospital which is infectious, pharmacy, hazardous and toxic waste, cytotoxic, sharp object.  The purpose of this research is to identify, a source of , the characteristics, solid waste medical produced by hospital X in Batam and also conduct an evaluation of solid waste medical management hospital in accordance with the minister of environment and forestry 56 2015 on procedures and technical requirements of hazardous and toxic waste management than health service facilities. This research used primary and secondary data collection method. The research results show solid waste medical management at the hospital X in Batam most of them are in according to rule. But there are some things that must be improved are blinding trash bag, efficiency and minimal temparature the combustion chamber incinerator. Management efforts must to do are briefing to officer of the waste collection about the way to blinding trash bag in according to the regulation and the incinerator that can serve confirming to standard of burning hazardous and toxic waste. <strong></strong></p>
