TL;DR: This paper reviewed literature and current practice regarding waste oil generation, regulations, collection, and reuse to identify research needs and approaches to increase the recovery and recycling of this resource, and revealed the need for research to address the following three waste oil challenges: (1) recover and recycle waste oil that is currently disposed of or misused; (2) identify and implement lubricating oil source and loss reduction opportunities; (3) develop and foster an effective waste oil recycling infrastructure that is based on energy savings, reduced environment at impacts, and competitive economics.
Abstract: Waste oil represents an important energy resource that, if properly managed and reused, would reduce US dependence on imported fuels. Literature and current practice regarding waste oil generation, regulations, collection, and reuse were reviewed to identify research needs and approaches to increase the recovery and recycling of this resource. The review revealed the need for research to address the following three waste oil challenges: (1) recover and recycle waste oil that is currently disposed of or misused; (2) identify and implement lubricating oil source and loss reduction opportunities; and (3) develop and foster an effective waste oil recycling infrastructure that is based on energy savings, reduced environment at impacts, and competitive economics. The United States could save an estimated 140 {times} 1012 Btu/yr in energy by meeting these challenges.

TL;DR: In this article, a process for utilizing waste by combining of the waste with a mineral-based solid material forming an additive is described. This additive is included as an ingredient in the manufacture of Portland cement with the additive being added to the cement clinker after heat treating of the raw material constituents producing the cement.

TL;DR: The use of waste materials and their products for highway construction is discussed in this paper, where the general legialation, local liability, and research projects related to waste materials are outlined.
Abstract: The use of waste materials and their products for highway construction is discussed. The general legialation, local liability, and research projects related to waste materials are outlined. The waste materials and products presented include waste paving, industrial ash, taconite tailings, waste tire rubber and products, building rubble, incinerator ash and products, waste glass, waste shingle and products, waste plastics and products, and slag. For each waste category, the legislation and restrictions, material properties, construction and application, field performance, and recycling at the end of service life, if available, are discussed. In addition, procedures for evaluation of and selection from waste alternatives are presented. Results from a survey sent to Minnesota city and county agencies are presented summarizing current practices in waste reuse for highway construction.

TL;DR: In this paper, the chemical characterization of the oils obtained from liquefaction of different coals with sugar cane bagasse oil and also from coal with monoethanolamine are presented.
Abstract: In the present work, the chemical characterization of the oils obtained from liquefaction of different coals with sugar cane bagasse oil and also from the liquefaction of coal with monoethanolamine are presented. Characterization of the oil samples was done with the add of spectroscopic and chromatographic techniques, including UV-vis, FTIR, NMR, preparative liquid chromatography (PLC) and high resolution gas chromatography (HRGC).
