How much are you polluting your office air just by existing?

Read the full story from Purdue University.

Could your basic acts of existence be polluting the air in the office room where you work? To find out, a team of engineers has been conducting one of the largest studies of its kind.

Sharing data for improved forest protection and monitoring

Read the full story from the International Institute for Applied Systems Analysis.

Although the mapping of aboveground biomass is now possible with satellite remote sensing, these maps still have to be calibrated and validated using on-site data gathered by researchers across the world. IIASA contributed to the establishment of a new global database to support Earth Observation and encourage investment in relevant field-based measurements and research.

Hazards mapping, history and the future of Rust Belt cities

Read the full story from Michigan Technological University.

Michigan Technological University researchers have developed a GIS-based model to identify the persistence of industrial hazards in postindustrial cities. Dan Trepal, a postdoctoral researcher and Don Lafrenière, associate professor of geography and GIS, both in the Department of Social Sciences, examined human risk of exposure to environmental hazards in postindustrial London, Ontario, through space and time, but the spatial-temporal model can be applied more widely. Trepal, who recently completed his doctorate in industrial archaeology and heritage, notes that the field reminds modern city-dwellers that our lives are layered on the past experiences and decisions of those who came before us.

New study analyzes FEMA-funded home buyout program

Read the full story from the University of Miami.

An analysis of FEMA’s 30-year-old property buyout program offers new insight into the growing debate on managed retreat — moving people and assets out of flood-prone areas.

Some corals ‘killed’ by climate change are now returning to life

Read the full story in New Scientist.

Reef-building corals can make unexpected recoveries from climate change-induced destruction. It turns out that some corals only look dead when exposed to unusually warm water. Instead, the coral’s polyps shrink and retreat into their hard skeleton, making the reef appear dead, before recolonising the skeleton when conditions are better. It is a survival strategy never seen before in today’s corals – but it may not help the corals as the climate continues to change.

How to make biocatalysts immortal

Read the full story from Ruhr-University Bochum.

Oxygen threatens sustainable catalysts that use hydrogen to produce electricity in fuel cells. Researchers have now developed a way to combat this.

Climate Change and Sustainability

Read the full story in American Libraries.

As public concern over climate change grows, libraries across the US have begun offering a wide range of programs on the topic—and, in at least one case, celebrating literature that supports and promotes environmental sustainability.

The new high-tech way to recycle old clothes

Watch the video from the BBC.

A Swedish recycling mill has developed a new way to reprocess old clothes.

Used cotton fabrics are separated and “de-dyed” to remove colour before being turned into a pulp called circulose.

The pulp is dried and then sold to textile companies to make thread. Garments made using this process can be recycled several more times.

With some 80 billion items of clothing produced globally each year, there is a huge potential for recycling.

Target and Walmart are trying to out-green each other in proving to customers they are environmentally responsible businesses.

National Emission Standards for Hazardous Air Pollutants: Generic Maximum Achievable Control Technology Standards Residual Risk and Technology Review for Ethylene Production: Proposed Rule

Comments due: November 25, 2019
Docket: EPA-HQ-OAR-2017-0357

The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP): Generic Maximum Achievable Control Technology Standards. The source category addressed in this action is Ethylene Production.

The EPA is proposing decisions concerning the residual risk and technology review (RTR), including proposing amendments pursuant to technology review for storage vessels and heat exchange systems. The EPA is also proposing amendments to correct and clarify regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM), including removing general exemptions for periods of SSM, adding work practice standards for periods of SSM where appropriate, and clarifying regulatory provisions for certain vent control bypasses. Lastly the EPA is proposing to add monitoring and operational requirements for flares; and add provisions for electronic reporting of performance test results and reports and Notification of Compliance Status (NOCS) reports.

We estimate that these proposed amendments will reduce hazardous air pollutants (HAP) emissions from this source category by 62 tons per year (tpy).
