Integrated waste management via the Natural Laws

Summary The basic tools of engineering, energy and material balances and rate expressions, provide a pathway to apply the Natural Laws of Hazardous Waste for proper waste management. Overall, one must focus on nature's limits, which are discussed, using open minded engineering practices for proper waste management. By expansion of balance concepts beyond end-of-pipe and integrating concepts beyond basic life-cycles, as discussed in this paper, the true impact ofwaste management practices may be established. These cradle-to-grave balances are connected to nature's limits via results of recent work by others on risk assessment. The combination of approaches for evaluating concentration limits of chemicals in the environment allows the facility for an engineering solution for proper waste management. The method is presented by making example comparisons of choices of technology for recycling, storage, and site remediation.
