Building materials recycler switches fleet to Neste renewable diesel

Green Car Congress

Since forming in 2013, Argent Materials, a San Francisco Bay Area recycler of concrete and asphalt, and supplier of aggregate such as crushed rock, entry, cutback, sand, backfill and base rock for construction projects, has diverted more than a billion pounds of waste from local landfills. Our experience has been positive.

Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

In a paper published in the ACS journal Environmental Science & Technology , Stanford University assistant professor Adam Brandt reviews a number of recent life cycle assessment (LCA) studies calculating greenhouse gas (GHG) emissions from oil sands extraction, upgrading, and refining pathways—the results of which vary considerably.

Stanford, UC Santa Cruz study explores ramifications of demand-driven peak to conventional oil

Green Car Congress

In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).
