Most of the United States have laws mandating the recycling of municipal solid waste (MSW). In order to comply, municipalities recycle quotas of materials, without regard to fluctuating prices. An inventory system is proposed that allows municipalities to be sensitive to materials prices as they recycle in accordance with state mandates. A dynamic model is developed; it uses historical secondary material prices as exogenous inputs to minimize the net present value of MSW recycling system cost. The model provides a cost-effective method for municipalities to achieve their MSW recycling targets. The savings is approximately $1.43 per ton of MSW generated based on total MSW management costs of $13.5 per ton. The model also allows one to investigate the... |

The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter, arguably the number-one environment-related public health threat facing the nation. We present an integrated process model of the engineering economics of technologies to reduce methane and ammonia emissions at dairy operations in California. Three policy options are explored: greenhouse gas offset credits for methane control, particulate matter offset credits for ammonia control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane gas. Individually, any of these policies appears to be sufficient to... |

The possibility that workers could be adversely affected by environmental policies imposed on heavily regulated industries has led to claims of a "jobs versus the environment" trade-off by both business and labor leaders. The present research examines this claim at the industry level for four heavily polluting industries: pulp and paper mills, plastic manufacturers, petroleum refiners, and iron and steel mills. By focusing on labor effects across an entire industry, we construct a measure relevant to the concerns of key stakeholders, such as labor unions and trade groups. We decompose the link between environmental regulation and employment into three distinct components: factor shifts to more or less labor intensity, changes in total expenditures, and... |

In this paper we develop a cost index-based measure of the expected consumer welfare gains from innovation in electricity generation technologies. To illustrate our approach, we estimate how much better off consumers would be from 2000 to 2020 as renewable energy technologies continue to be improved and gradually adopted, compared with a counterfactual scenario that allows for continual improvement of conventional technology. We proceed from the position that the role and prospects of renewable energy are best assessed within a market setting that considers competing energy technologies and sources. We evaluate five renewable energy technologies used to generate electricity: solar photovoltaics, solar thermal, geothermal, wind, and biomass. For each, we... |
