What is integrated waste management? What decisions would be part of a stewardly and sustainable solid-waste management plant?
What will be an ideal response?
Source reduction, waste-to-energy combustion, recycling, material recovery facilities, landfills, and composting are all a part of integrated waste management, "a system having several processes in operation. . . ." A stewardly and sustainable solid waste management plan would start with source reduction. A second, equally important component would be to establish a system of "‘unit pricing' or charging households and other ‘customers' for the waste they dispose." A third policy would be to "establish a program of extended product responsibility (EPR), a concept that involves assigning some responsibility for reducing the environmental impact of a product at each stage of its ‘lifecycle,' especially the end. For example, Hewlett-Packard and Xerox make it easy for customers to return spent copier cartridges, and the two companies recycle the components of the cartridges." Some portion of our waste will be burned in a waste-to-energy facility, some component (the largest) would be recycled, and some component would be landfilled. Once a component of the waste is recycled, we need to encourage the purchasing of goods with recycled content.
"Here is one ideal stewardly waste management plan: (1) emphasize source reduction wherever possible; (2) employ mandatory curbside recycling and a PAYT collection program; (3) if feasible, establish a MRF for efficient handling of recyclables (and possible MS); (4) employ co-composting of remaining MSW with treated sewage sludge; (5) deposit residual materials in a local landfill; and (6) prohibit all interstate transfer of MSW."

The process of cloud seeding is based on the theory that:
A) warm clouds will produce more rain if droplets are encouraged to freeze inside the cloud. B) silver iodide crystals act as freezing nuclei and enhance the Bergeron process. C) silver iodide crystals make droplets heavier than usual so that they fall to the ground. D) it is impossible to add too many freezing nuclei; the more you add, the more rain will fall.

Why do igneous rocks have so many uses (anything from building stone to abrasive in toothpaste)?
