Decisions on the strategies to follow in dealing with these operational and decommissioning wastes require consideration of a wide range of issues including environmental impact, safety, stakeholder acceptability, cost and practicability. In this paper, we focus on an approach that we have developed to analyse the time-varying resource requirements of different waste management options in terms of cost and plant capacity. The approach addresses the need for: • a standardised approach that can be used across different organisations; • a range of standard graphical outputs that can be used to communicate the key issues; • the need to match waste management strategy with the potential availability of relevant plant and facilities; • the need to evaluate the risks that arise to any strategy as the result of changes in policy or the failure of some component of the strategy. Many of the required issues can be addressed using a simple spreadsheet approach. However, this does not provide for standardisation, auditability or transparency and does not provide a wide range of analysis and presentation tools. We therefore advocate the use of a specifically designed decision support tool. ALPS (Advanced Liabilities Planning System) has been developed over a number of years to meet these requirements. It has been developed around the database package ACCESSTM and runs on Pentium TM PCs but has the essential features of project management packages that are necessary for strategic planning. The principal outputs of the system are cost, timing and utilisation data for waste stores, processing facilities, transport and disposal operations. The outputs can be displayed at any level of aggregation to allow the effects of different scenarios to be evaluated.

Absorbent hygiene products (AHP) have received much interest due to the notion that their end-of-life (EoL) stage has high environmental impacts. Since the use of AHP will continue to rise in the foreseeable future, information that helps with a reduction in the environmental impacts of AHP through their life cycle is needed. This research presents an estimation of AHP in municipal waste, and it also reviews and discusses waste management options, available treatments at bench, pilot or full scale, and life cycle assessments (LCAs) available in the literature. Municipal waste of countries belonging to the Organization for Economic Co-operation and Development contains on average 2.7% of baby nappies, 4.8% of adult nappies and 0.5% of sanitary pads (in weight), whereas that of Latin-American countries have 7.3%, 3.3%, and 0.9%, respectively. Management options for AHP waste in developed countries are landfilling and incineration, while in developing countries AHP are disposed of in dumpsites and landfills. Most LCAs identify significant environmental impacts in the production of raw materials, while EoL scenarios involving incineration and landfill were found to have a significant contribution to global warming potential. Substitution with alternative products has been suggested as a way of decreasing environmental impacts; however, their use frequently causes a trade-off on different impact categories. Municipalities could use a wide range of policy tools, such as extended producer responsibility systems, bans, levies, ecolabelling, or a combination of these, to reduce the environmental and economic burden of AHP waste.

Definition Of

Life Cycle Assessment (LCA) is a decision support tool that can be used to assess the environmental performance of an integrated waste management system or to identify the system with the best performance through a comparative analysis of different scenarios. The results of the analysis depend primarily on how the scenarios to be compared are defined, that is on which waste fractions are assumed to be sent to certain treatments/destinations and in what amounts. This paper reviews LCAs of integrated waste management systems with the aim of exploring how the scenarios to be compared are defined in the preliminary phase of an LCA. This critical review highlighted that various criteria, more or less subjective, are generally used for the definition of scenarios. Furthermore, the number of scenarios identified and compared is generally limited; this may entail that only the best option among a limited set of possibilities can be selected, instead of identifying the best of all possible combinations. As a result, the advisability of identifying an integrated life cycle-based methodological approach that allows finding the most environmentally sound scenario among all of those that are theoretically possible is stressed.

ABSTRACT #1141234 The coastal waters of Canada embrace a wide range of physical environments and ecosystems from the warm, sediment-rich waters of the Bay of Fundy to the nutrient-limited cold waters of the high Arctic. This range of biophysical characteristics impacts natural attenuation and weathering processes for oil stranded on shorelines. This study was conducted to: 1) identify and quantify the primary regional parameters that control shoreline oil translocation (removal) processes and pathways and 2) define the effectiveness and environmental consequences of current and potential oiled shoreline treatment strategies and tactics. A specific knowledge gap, here and elsewhere in the world, has been in understanding how the distribution and character of fine-grained sediments affect stranded oil attenuation. Fine-grained sediments (<1mm) can play a critical role in natural or induced (that is, shoreline treatment) oil dispersal. Shoreline sediment samples were collected and analyzed from representative locations on Arctic, Atlantic, and Pacific Ocean beaches to provide a broad geographic characterization of mineral fines at the regional level. This knowledge is the basis for an “Oiled Shoreline Response Program (SRP) Decision Support Tool” to aid spill scientists, students, environmental resource managers, spill responders and the public in understanding the response methods and the ramifications and consequences of their shoreline treatment options without the need to digest technical papers, large reports, or data bases. This MPRI SRP Decision Support Tool is intended to be a dynamic, interactive, multi-layered, geographically and seasonally-based model for shoreline oil spill response decision analyses. A goal of this interactive model is to move away from the traditional static format of learning from explanations in text reports and publications to an interactive tool that encourages its users to explore and fully understand the significance of the different environmental factors outlined in publications and data bases. Recent advances in web technology make this possible. The development of user interface platforms such as React, libraries such as D3, and notebook forms like Observable has created a palette of technologies that together make web application patterns such as Documodels a much more streamlined development process. The power of this medium is to convey a complex subject and to enable a user to grasp keen insights and so understand the consequences of intervention decisions.

<p>Under the context of the H2020 S2S4E project, industrial and research partners co-developed a fully-operational Decision Support Tool (DST) providing during 18 months near real-time subseasonal and seasonal  forecasts tailored to the specific needs of the renewable energy sector. The tool aimed to breach the last mile gap between climate information and the end-user by paying attention to the interaction with agents from the sector, already used to work with weather information, and willing to extend their forecasting horizon by incorporating climate predictions into their daily operations.</p><p>With this purpose, the tool gathered a heterogeneous dataset of seven different essential climate variables and nine energy indicators, providing for each of them bias-adjusted probabilistic information paired with a reference skill metric. To achieve this, data from state-of-the-art prediction systems and reanalysis needed to be downloaded and post-processed, fulfilling a set of quality requirements that ensure the proper functioning of the operational service. During the design, implementation, and testing phases, a wide range of scientific and technical choices had to be made, making clear the difficulties of transferring scientific research to a user-oriented real-time service. A brief showcase will be presented, exemplifying the different tools, methodologies, and best practices applied to the data workflow, together with a case study performed in Oracle’s cloud infrastructure. We expect that by making a clear description of the process and the problems encountered, we will provide a valuable experience for both, upcoming attempts of similar implementations, and the organizations providing data from climate models and reanalysis.</p>
