Veolia launches largest project to produce bio-methanol from pulp mill waste

Green Car Congress

Black liquor is the waste byproduct from the kraft pulping process after pulping is completed. With an annual production capacity of 12,000 tons (about 15 million liters), the plant, due to come on stream by 2024, will allow the avoidance of up to 30,000 tons of CO 2 emissions per year by replacing fossil fuel for transportation.

Pitt engineers using membrane distillation to recycle water used in fracking and drilling

Green Car Congress

Engineers at the University of Pittsburgh Swanson School of Engineering are using membrane distillation technology to enable drillers to filter and reuse the produced water in the oil and gas industry, in agriculture, and other beneficial uses. The method is already being tested in Texas, North Dakota, and most recently in New Stanton, Pa.

PNNL team finds biocrude from kelp and fish waste via hydrothermal liquefaction could be viable fuel for remote Alaskan communities

Green Car Congress

Using existing fish processing plants, kelp and fish waste can be turned into a diesel-like fuel to power generators or fishing boats in rural, coastal Alaska, according to a team from Pacific Northwest National Laboratory (PNNL). The waste-to-energy fuel could then be used to power generators or fishing boats.

Raven SR to supply sustainable aviation fuel to ANA and JAL

Green Car Congress

Raven SR signed memoranda of understanding (MOU) to supply sustainable aviation fuel (SAF) to All Nippon Airways (ANA) and to Japan Airlines (JAL) for major global routes. Global SAF supply currently comprises 0.03% of total jet fuel consumption due to a limited supply of feedstock like used cooking oils and tallow.

NTNU researchers use reverse electrodialysis and waste heat for hydrogen production: Heat to H2

Green Car Congress

A new approach developed by researchers at the Norwegian University of Science and Technology (NTNU) could alleviate that situation a bit by using waste heat from other industrial processes. Energy experts say that the waste heat from Norway’s businesses and industries is the equivalent of 20 TWh of energy. —Krakhella et al.
