Gasoline-like fuel suitable for internal combustion engines can be obtained from the pyrolysis of plastic waste, according to a study conducted by a team of people from Gadjah Mada University (Yogyakarta, Indonesia; www.ugm.ac.id), University Sains Malaysia (Penang, Malaysia; www.usm.my), and…
Scientists at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) have developed a continuous process for generating crude oil from algae that they believe can lower the cost of producing algae-based fuel. The process works by combining hydrothermal liquefaction and…
A high-throughput method for synthesizing ionic-liquid-containing electrolytes developed by Boulder Ionics Corp. (Arvada, Colo.; www.boulderionics.com) has been refined to enable its use in commercial production. Boulder Ionics had previously piloted the continuous process for producing advanced ionic-liquid (IL) electrolytes at…
Offgases containing compounds of chlorine or fluorine are typically burned to enable the recovery of HCl or HF and prevent release into the environment. However, conventional combustion chambers require a long time to heat up, and thus are typically run…
Extraction of palm oil generates large amounts of lignocellulose-rich byproduct known as empty fruit bunch (EFB), which is usually wasted. A new process for utilizing this waste to make lactic acid has been developed by a team of researchers in…
Professor Takao Masuda and colleagues at Hokkaido University (Sapporo; www.eng.hokudai.ac.jp/labo/cse), in collaboration with Idemitsu Kosan Co. (Idemitsu; Tokyo; both Japan; www.idemitsu.com), have developed a two-step process that converts wood-based lignin into phenols. They believe the achievement could lead to an…
An Australian team has implemented several changes to the conventional organic rankine cycle, resulting in a highly efficient regenerative thermodynamic cycle for producing electricity from waste heat and other thermal sources. The University of Newcastle’s Priority Research Center for Energy…
A metal-free catalyst system involving ionic liquids and doped carbon nanofibers can efficiently reduce carbon dioxide to carbon monoxide, offering a cost-effective electrochemical route from CO2 to synthesis gas (syngas), and further, to liquid transportation fuels. A research group at…
A new method for removing uranium and other heavy metals (HMs) from wastewater has been developed by researchers at the University of Eastern Finland (Joensuu; www.uef.fi). The technology has been licensed by Oy Chemec AB (Espoo, Finland; www.chemec.fi), which plans…
Sludge dewatering Last month, Metso Corp. (Helsinki, Finland; www.metso.com) introduced what it claims to be the worlds first advanced solution — both measurements and control system — to optimize sludge dewatering at wastewater treatment plants. The Metso SDO (sludge…
