The US Environmental Protection Agency (EPA) has awarded 21 research grants to explore the impacts of nanomaterials on public health and the environment. Along with the many benefits of nanomaterials comes the threat of toxicity, accumulation, or other adverse effects on humans and the environment.

Nanoparticles are already used in many consumer products such as cosmetics, fabrics, appliances, sports equipment, and packaging. Research proposals that have been awarded grants include

The Viridis Septage Bioreactor Landfill is proprietary technology that speeds up the decomposition of solid waste by combining it with sewage. The resulting methane gas can be used as fuel to generate electricity, or to enhance natural gas supplies.

The system makes available a constant supply of renewable energy, increases landfill space, and provides an opportunity for revenue from fuel sales. Other benefits include
