Hands-on assistance improves already successful pollution prevention services of the toxics use reduction institute’s laboratory

In an attempt to improve the adoption rate of the work conducted at the Toxics Use Reduction Institute Lab, a more comprehensive on-site follow-up assistance program was implemented in 2006. The effort was piloted for trichloroethylene replacement in Rhode Island in conjunction with Environmental Protection Agency (EPA) Region 1.Through hands-on workshops and on-site assistance efforts, the TURI Lab project was able to achieve an 82% reduction in TCE in a two year period. This new methodology for on-site assistance follow-up to the preexisting TURI Lab testing program has been incorporated into the work the Lab conducts for companies in Massachusetts. The Lab had an implementation rate of around 30% without on-site assistance. During the first year of the new process, the adoption rate has jumped to 80% of all companies working with the lab.     

The privatization effect of MSW incineration services by using data envelopment analysis

This paper attempts to compare the relative efficiency across MSW incineration facilities under the three operating modes including government-owned government-operated (GOO), government-owned private-operated (GOPO), and private-owned private-operated (POPO) by using the Data Envelopment Analysis (DEA), and to examine the factor in affecting the efficiency variation. The results show that technical efficiency scores are 0.7538, 0.9046 and 0.9917 for GOO, GOPO and POPO, respectively. An ANOVA is conducted and the analysis result confirms that the operating mode has significant impact on technical efficiencies. A further examination on the operating contracts signed between governments and operating firms of GOPO facilities finds that both the price protection and quantity protection also play vital roles in affecting efficiencies.
