Municipal authorities increasingly view environmental protection as one of the goals of city management. The pro-environmental orientation of cities can, therefore, foster the creation of new management methods and instruments and promote reorganization of determining material flows in a municipal system. Activities of this kind should result not only in the reduction of generated waste but also in the creation of closed material cycles. Considering the tasks of Polish local governments, municipalities should pay the most attention to municipal waste. Accordingly, the goal of this study was to identify the problem of mixed municipal waste in cities and assess the influence of investments into fixed assets for environmental protection in the scope of waste management on the quantity of mixed municipal waste in cities. This article also identifies activities for circular resource management that need to be realized by Polish municipalities. The analysis was performed using the panel model, dynamic indexes, and critical analysis of city documents. The conducted research revealed positive trends in cities with respect to the amount of waste collected non-selectively that is conducive to circular resource management. The fact that municipal waste quantity is on the increase should encourage urban authorities to promote pro-environmental waste management behaviors among city dwellers.

In the Marche Region (Central Italy), the residual municipal waste (RMW) is commonly processed in mechanical biological treatment (MBT) systems. In these systems, following a first mechanical selection, the undersize organic fraction from RMW (us-OFRMW) undergoes a partial aerobic biological treatment before being landfilled as a biostabilised fraction (bios-OFRMW) without dedicated energy or material recovery. Alternative us-OFRMW management scenarios have been elaborated for this region, at both present (reference year 2019) and future (reference year 2035) time bases. In the first scenario, the potential bioenergy recovery through anaerobic digestion (AD) from the us-OFRMW was evaluated. The second scenario aimed at evaluating the residual methane generation expected from the bios-OFRMW once landfilled, thus contributing also to the potential environmental impact connected with landfill gas (LFG) diffuse emissions from the regional landfills. The diversion to AD, at the present time, would allow a potential bioenergy recovery from the us-OFRMW equal to 4.35 MWel, while the alternative scenario involves greenhouse gas (GHG) emissions equal to 195 kg CO2 eq. per ton of deposited bios-OFRMW. In the future, the decreased amount of the us-OFRMW addressed to AD would still contribute with a potential bioenergy recovery of 3.47 MWel.

Municipal waste from day to day has increased its production in line with the increase of urban population. However, running a waste management system has been unable to solve the problem of waste properly. Therefore, a new breakthrough is needed to deal with. With the enactment of Law No. 18 of 2008 on Waste Management, each source must be to reduce the amount of waste to be disposed of to the final processing of waste. The office is one of the sources of waste, also must reduce the amount of waste that must be disposed of to the final processing of waste (landfill). The purpose of this paper is to examine waste management in an integrated manner to maximize the waste management office. In the process of management, garbage collector used by officers in the study. The rest moved to the TPS waste. In this place officers also collect that is still valuable economic and processed organic waste into compost. Of these operations, the rest of office waste disposed to landfill about 48.7%keywords : office waste, integreted office waste management

The paper describes the technology of passive degassing of solid municipal waste landfill facilities. When landfill gas penetrates into the environment it causes negative effects. The described method is used to prevent uncontrolled emission of landfill gas into atmosphere. Passive degassing of solid municipal waste landfill is carried out with the help of a chain of gas draining boreholes. The technique for calculating the chain of gas draining boreholes and their structural design has been given.

The US Department of Energy Office of Environmental Management (DOE-EM) oversees one of the largest and most technically challenging cleanup programs in the world. The mission of DOE-EM is to complete the safe cleanup of the environmental legacy from five decades of nuclearweapons development and government-sponsored nuclear energy research. Since 1995, Florida International University’s Applied Research Center (FIU-ARC) has supported the DOE-EM mission and provided unique research capabilities to address some of these highly technical and difficult challenges. This partnership has allowed FIU-ARC to create a unique infrastructure that is critical for the training and mentoring of science, technology, engineering, and math (STEM) students and has exposed many STEM students to “hands-on” DOE-EM applied research, supervised by the scientists and engineers at ARC. As a result of this successful partnership between DOE and FIU, DOE requested FIU-ARC to create the DOE-FIU Science and Technology Workforce Development Initiative in 2007. This innovative program was established to create a “pipeline” of minority STEM students trained and mentored to enter DOE’s environmental cleanup workforce. The program was designed to help address DOE’s future workforce needs by partnering with academic, government and private companies (DOE contractors) to mentor future minority scientists and engineers in the research, development, and deployment of new technologies and processes addressing DOE’s environmental cleanup challenges. Since its inception in 2007, the program has trained and mentored 78 FIU STEM minority students. Although, the program has been in existence for only six years, a total of 75 internships have been conducted at DOE National Laboratories, DOE sites, DOE Headquarters and field offices, and DOE contractors. Over 100 DOE Fellows have participated in the Waste Management (WM) Symposia since 2008 with a total of 84 student posters and 7 oral presentations given at WM. The DOE Fellows participation at WM has resulted in three Best Student Poster Awards (WM09, WM10, and WM11) and one Best Professional Poster Award (WM09). DOE Fellows have also presented their research at ANS DD&R and ANS Robotics Topical meetings and this year two Fellows will present at the International Conference on Environmental Remediation and Radioactive Waste Management (ICEM13) in Brussels, Belgium. Moreover, several of our DOE Fellows have already obtained employment with DOE-EM, other federal agencies, DOE contractors, commercial nuclear power companies, and other STEM industry (GE, Boeing, Lockheed Martin, Johnson & Johnson, Beckman-Coulter, and other top companies). This paper will discuss how DOE Fellows program is training and mentoring FIU STEM students in Department of Energy’s Office of Environmental Management technical challenges and research. This training and mentoring has resulted in the development of well-trained and polished young scientists and engineers that will become the future workforce in charge of carrying on DOE-EM’s environmental cleanup mission. The paper will showcase FIU’s DOE Fellows model and highlight some of the applied research the DOE Fellows have conducted at FIU’s Applied Research Center and across the DOE Complex by participating in summer internship assignments.

AbstractSeparate collection of biodegradable municipal waste (BMW) is the main precondition to decrease the environmental pollution by landfill gas as well as to enrich soil by the humus substances from municipal compost. However, the obligation to ensure the separation and treatment of the BMW increases the municipalities' costs for waste management. Rural areas differ from the urban ones not only by typical lifestyle, settlement character, but also by total BMW production. The urban areas do have easier access to public finances, therefore, most of them already dispose sufficient infrastructure for BMW gathering and treatment. The aim of our research was to analyze the spatial production and disposal of the biodegradable municipal waste and propose, in regard to legislation, efficient BMW treatment for rural areas of the Nitra region. The analysis revealed that only 23% of the examined municipalities dispose through composting. However, 92% of them have the estimated annual BMW production from public green areas not exceeding 100t. Organic waste processing could be managed by municipalities through “small composting” which does not require the approval by the state body in waste management.
