Daniel A. Vallero, Chapter 13 - Air pollution control technologies, Editor(s): Daniel A. Vallero, Air Pollution Calculations, Elsevier, 2019, Pages 377-428, 9780128149348
This book chapter advances SDGs 3, 13 and 15 by discussing various sources of air pollution and technologies to remove and treat pollutants.
Each year the RELX Environmental Challenge is awarded to projects that best demonstrate how they can provide sustainable access to safe water or sanitation. Projects must have clear practical applicability, address identified need and advance related issues such as health, education, or human rights. Applications close on 7 June 2019.
RELX held its fourth SDG Inspiration Day in Delhi to catalyse action on the UN Sustainable Development Goals. This event took place at the iconic Imperial Hotel in partnership with Global Compact India, Responsible Media Forum and the Ban Ki-Moon Centre for Global Citizens. The theme Sustainable Cities: SDG 11, critical to the rest inspired rich discussion among participants from business, government, civil society and academia who explored the interconnection of SDG 11 with cross-cutting themes, such as health and the rule of law.
PET is a ubiquitous material because of its robust properties. Today, less than 30% of PET bottles and few carpets are recycled in the United States, leading to the majority of PET being landfilled. The low PET reclamation rate is due to the fact that PET bottle recycling today is mechanical, resulting in a devalued product. Here, reclaimed PET (rPET) bottles are converted to fiberglass-reinforced plastics (FRPs), which sell for more than twice that of rPET. When monomers derivable from biomass are incorporated, rPET-FRPs with superior properties are achieved.
Background: Men who have sex with men (MSM) are disproportionately affected by HIV and other sexually transmitted infections (STIs) worldwide. Previous reviews investigating the role of circumcision in preventing HIV and other STIs among MSM were inconclusive. Many new studies have emerged in the past decade. To inform global prevention strategies for HIV and other STIs among MSM, we reviewed all available evidence on the associations between circumcision and HIV and other STIs among MSM.
Tire materials are a significant proportion of the (micro)plastics in the environment that until today have been clearly overlooked. These materials are released into the environment, either unintentionally as an abrasion product from tire wear, that reaches the environment via road runoff, or intentionally as, for example, shredded “tire crumble rubber” used as filling material for playgrounds.
Microplastic (MP) studies in freshwater environments are gaining attention due to the huge quantities of plastic particles reported from lakes and rivers and the potential for negative impacts in these environments. Different units have been used to report MP densities, which makes it difficult to compare data and can result in reports of extremely high concentrations that do not reflect the original sample size. We recommended that the density of MPs from bulk samples be reported as number L −1 , while density from net samples should be reported as number m −3 .
Plastic pollution is a global problem since 2016 when its production reached 322 million tonnes, excluding fibers. Daily discharges of microplastics (MPs, defined as
Lithium ion batteries (LIB) continue to gain market share in response to the increasing demand for electric vehicles, consumer electronics, and energy storage. The increased demand for LIB has highlighted potential problems in the supply chain of raw materials needed for their manufacture. Some critical metals used in LIB, namely lithium, cobalt, and graphite are scarce, are not currently mined in large quantities, or are mined in only a few countries whose trade policies could limit availability and impact prices.
