  • CORAR Position Paper on Mixed Waste

CORAR is comprised of representatives of the major manufacturers and distributors of radiopharmaceuticals, radioactive sources, and research radionuclides used in the U.S. for therapeutic and diagnostic medical applications and for industrial, environmental and biomedical research and quality control. Radiophamaceuticals and radionuclides are used world wide with immense benefit to society. Although non-radiometric methods are being sought, much essential biochemical and medical research today depends on the application of radionuclides often in the form of labelled compounds. It is interesting to note that in the past twenty-five years most Nobel prizes in medicine and physiology were awarded for research which could not have been conducted without radioactive materials. In addition to benefits accruing from research, the quality of health care is also strongly enhanced by diagnostic and treatment methods using radiopharmaceuticals and radioactive sources. Some medical treatments and diagnostics can only be done using radionuclides. Currently, when other methods are available, they are less safe, less accurate and/or are more costly than the radiometric method. An unavoidable by-product of the manufacture and use of these essential radioactive products is the generation of mixed waste. Although manufacturers and users continue to seek methods to avoid the production of mixed waste, it is unlikely that mixed waste will be entirely eliminated and the ultimate fate of mixed waste currently held in storage is still to be determined.

The alternatives analyzed were: the No Action Alternative, the Proposed Action, the Non-Thermal Treatment Alternative, and the Treatment and Storage Alternative. The Proposed Action is the Preferred Alternative. Under the Proposed Action/Preferred Alternative, the AMWTP facility would treat transuranic waste, alpha-contaminated low-level mixed waste, and low- level mixed waste in preparation for disposal. After treatment, transuranic waste would be disposed of at the Waste Isolation Pilot Plant in New Mexico. Low-level mixed waste would be disposed of at an approved disposal facility depending on decisions to be based on DOE’s Final Waste Management Programmatic Environmental Impact Statement.

  • Review of the Risk Screening Assessment for the Mixed Waste Landfill, SWMU76
    Review of the Risk Screening Assessment for the Mixed Waste Landfill, SWMU76 By Marvin Resnikoff, Ph.D. Radioactive Waste Management Associates The following report was made possible with a grant from the Monitoring and Technical Assessment Fund (MTA) to assist in performing independent technical studies of the Mixed Waste Landfill (MWL), a hazardous waste site containing radioactive and chemical legacy wastes located at Sandia National Laboratories (SNL). The funding, established as a part of a $6.25 million court settlement between the U.S. Department of Energy (DOE) and 39 nonprofit and environmental groups, assists tribes and other non-governmental organizations in conducting their own independent technical studies of sites at DOE facilities. Citizen Action commissioned Dr. Marvin Resnikoff, Radioactive Waste Management Associates, New York, to review Sandia National Laboratories’ risk assessment for the Mixed Waste Landfill and evaluate whether the objectives identified under the Phase 2 RCRA Facility Investigation to “determine thoroughly the contaminant source, define the nature and extent of contamination, identify potential contaminant transport pathways, evaluate potential risks posed by the levels of contamination identified, and recommend remedial action, if warranted, for the landfill” were satisfied. A copy of Dr. Resnikoff’s curriculum vitae is included with this report. “…the contaminant source has not been identified and the potential risks posed by the landfill have not been fully evaluated.” - Marvin Resnikoff, Ph.D.

  • The Municipal Solid Waste Management System with Anaerobic Digestion
    energies Article The Municipal Solid Waste Management System with Anaerobic Digestion Przemysław Seruga Department of Bioprocess Engineering, Wroclaw University of Economics and Business, Komandorska 118/120, 53-345 Wroclaw, Poland; [email protected]; Tel.: +48-713-680-872 Abstract: This study investigated the applied methods for the collection and treatment of an organic fraction of municipal solid waste with anaerobic digestion (AD), including the effects of selective waste collection system introduction. As the research area, data from a waste treatment plant, which collects waste from about 260,000 inhabitants, was used as the selected waste management plan. Biowaste stream management was emphasized. Thus, research on energy recovery and the characteristics of digestate (nutrient and heavy metals content) obtained from biowaste AD was performed. The results of the studies and their quantitative data were interpreted. A significant discrepancy between the assumptions and the actual situation was revealed (up to 20% year-on- year regarding biowaste). An underestimation of the amount of waste when planning was noted. AD ensures energy recovery from biowaste, which can cover facility electricity needs and material recovery. The digestate might find agricultural usage and become an ecological product. The content of nitrogen (1.5%dry matter), phosphorus (0.55%dry matter), potassium (1.0%dry matter), and organic carbon (16.0%dry matter) indicate a positive impact on crops. Furthermore, it can improve the economic balance, by replacing costs with sales revenues.

  • Basic Solutions to Waste Management Issues That Will Bring Clean Culture in India
    E3S Web of Conferences 170, 0400 (2020)4 https://doi.org/10.1051/e3sconf/202017004004 EVF'2019 Basic Solutions to Waste Management Issues That Will Bring Clean Culture in India Bharati Koot1 1305-Gulmohar Imperial, Dhayari, Pune - 411041, India Abstract. The latest population of India is around 1.37 billion and India ranks number two by population in the world. With the increasing population, the obvious thing, the waste generated per day continues to increase. India generates around 65 million tonnes of waste every year and out of which most of the part is not collected, remains untreated at landfills or open areas. This is ruining the beauty of India. And this is already impacting largely on environment, climate, soil, water bodies, national health, and tourism. That also means the waste in India is heading to largely affect the national economy and the global environment. This paper attempts to go back to the basics of human nature and habits, needs and mechanisms for shifting them for the context of waste management and anti-littering to bring clean India forward and contribute to preventing the global environmental crisis. 1 Introduction India generates around 65 million tonnes of waste every year and out of which most of the part is not collected, This section depicts the introduction to the topic of this remains untreated at landfills or open areas. Landfills are paper. the 3rd largest cause of greenhouse emissions in India Littering and poor waste segregation are a few of the [1]. They cause air, food, land, and water pollution. The key factors which make waste management difficult in toxic leachate generated at landfills and landfills India and everywhere.
