Insulated kilns cut fuel cost over 50 percent

Residue-Derived Solid Recovered Fuel for Use in Cement Kilns

Appendix B. Tables for the 50-Percent Reduction Case

Ten-percent solar-to-fuel conversion with nonprecious materials.

Direct solar-to-fuels conversion can be achieved by coupling a photovoltaic device with water-splitting catalysts. We demonstrate that a solar-to-fuels efficiency (SFE) > 10% can be achieved with nonprecious, low-cost, and commercially ready materials. We present a systems design of a modular photovoltaic (PV)-electrochemical device comprising a crystalline silicon PV minimodule and low-cost hy...

Criteria for limits on the emission of dust from cement kilns that burn waste as fuel

This note performs a cost-benefit analysis of proposed limit values for the emission of dust from cement kilns that use waste as fuel (currently under discussion between the European Council and the European Parliament as part of the new Directive to regulate the emissions by facilities that incinerate waste). The estimation of benefits is based on the most recent results of the ExternE Project...

Biodiesel: A Cost-effective Fuel Using Waste Materials

The main disadvantage of biodiesel is its high price. The price of biodiesel depends on various factors such as the price of oil, methanol, catalyst, and labor. Among dif-ferent economic factors, oil accounts for the largest share of input costs of biodiesel production. In this study, first, suitable heterogeneous catalysts were identified for biodiesel production. Several studies were carried ...
