Promotion of resource efficiency and development towards a circular economy is widely supported. Many products and materials that are brought into the economy contain hazardous substances. These substances may be acceptable during the consumption stage, but due to accumulation in the environment may also cause impact to human health and the environment after consumption. The primary goal of was...

To better understand the composition of contaminants of emerging concern (CECs) in landfill leachate, fresh leachate from 19 landfills was sampled across the United States during 2011. The sampled network included 12 municipal and 7 private landfills with varying landfill waste compositions, geographic and climatic settings, ages of waste, waste loads, and leachate production. A total of 129 ou...

Methane emissions from municipal landfills represent 3% of the total United States greenhouse gas emissions that contribute to climate change. These methane emissions can be released to the air or collected and flared. This landfill gas also has the potential to be used to generate electricity. In 1994,the Environmental Protection Agency(EPA) created the Landfill Methane Outreach Program, with ...

Ultimately, hundreds of billions of dollars of public and private funds will be spent in the US in hazardous chemical site (Superfund and closed RCRA facilities) investigation and remediation. A critical review of the adequacy of remediation of many of these sites that are “closed” in accord with RCRA and/or CERCLA requirements as being interpreted by regulatory agency staff/boards and principl...

Landfill gas produces ozone precursors such as nitrogen oxides and formaldehyde when combusted in flares or stationary engines. Solid waste landfills are also the third largest anthropogenic source of methane United States. Methane is both a greenhouse tropospheric precursor. Despite its low photochemical reactivity, may noticeably affect urban if released large quantities along with other orga...
