The Integrated Solid Waste Management group at North Carolina State University is currently developing a publicly available life-cycle optimization model capable of analyzing solid waste management (SWM) performance – at both the individual process and integrated system levels – taking into account implications of greenhouse gas mitigation policies and competing SWM objectives (e.g., costs, emissions, and diversion targets). This life-cycle model is intended to estimate the costs, emissions, and environmental impacts associated with the processes (e.g., collection, separation, waste-to-energy, composting, anaerobic digestion, landfilling) that constitute the SWM system. As part of this research they are developing and updating life-cycle models for composting operations. In order to ensure that the models are as accurate and up-to-date as possible they are collecting data from composting facility operators. Identifying information is not required and will not be shared if provided. Their plan is to aggregate the data from a number of facilities to provide an up-to-date life-cycle model for composting operations. The final composting model as well as the entire life-cycle optimization model will be publicly available upon completion. Please answer all of the questions to the best of your ability, and feel free to skip any questions that you prefer not to answer. Thank you for your time.
