WastePlan allows users to build integrated solid waste plans. Any number of distinct sectors and waste types can be defined. The generated wastes are sent through user-defined sequences of source reduction, composting, recycling, and garbage collection. Finally, the wastes are routed to various facilities such as transfer stations, incinerators, landfills, recycling, or composting facilities. The results of this simulation describe waste flows, diversion rates, equipment and labor requirements, processing and disposal capacity needs, total costs, and costs per ton. Assumptions regarding technologies, efficiency, etc., can be altered. WastePlan has generally been applied for the following types of analyses.
Raw material acquisition | --- |
Manufacturing stage | |
Use/reuse/maintenance | --- |
Recycle/waste management |
The manufacturing stage is covered to the extent that source reduction is included in the analysis.
Conventional | |
Potentially hidden | --- |
Contingent | --- |
External | --- |
Typical costs included are labor, administrative and operating costs. Some other costs such as long-term care costs for landfills can also be included.
Cost information is estimated and entered into the system by users.
Net present value (NPV) | |
Payback period | --- |
Internal rate of return (IRR) | --- |
Benefits cost ratio | --- |
Other | --- |
The system calculates the NPV of the solid waste plan.
WastePlan features context-sensitive help screens, choice of mouse or keyboard input, and an on-screen display of the entire data structure. Various report and graph options are also available. The system is designed as a very flexible, generic system. WastePlan has an interactive database that takes changes in waste-flow into account. For example, if the generation rate changes, the diversion rates will automatically change.
WastePlan does not include contingent, hidden, and external costs in the analysis. It is not designed for life-cycle cost analysis. It focuses on the waste management portion of the life-cycle, and thus does not include other costs and environmental impacts of products, processes, and raw materials that are responsible for generating the waste. The downside of the system flexibility is that there is very little default information in the system, and users have to source and develop a lot of information on their own (or with technical support from Tellus).
