Plastic marine pollution is a significant environmental concern, yet a quantitative description of the scope of this problem in the open ocean is lacking. Here, we present a time series of plastic content at the surface of the western North Atlantic Ocean and Caribbean Sea from 1986 to 2008. More than 60% of 6136 surface [...]

We find that total consumption of PET resin grew at 2.7% per year over the period of the study, reaching 5.01 million metric tons in 2007. This growth was driven largely by the beverage packaging market, which accounted for 55% of consumption in 2007. About a quarter of PET bottles are collected for recycling, a [...]

Solid waste management is gaining significant importance with the ever-increasing quantities of waste materials generated these days. With increased environmental awareness and its potential hazardous effects, recycling/utilization of these materials have become an attractive alternative to disposal. Some of these waste and hazardous materials could possible be used in cement-based materials. One of such waste [...]

The technology, called hydraulic launch assist, is different from the electric hybrid technology currently used on some passenger cars and buses. Those systems use an electric-motor generator, along with batteries, to store energy that would otherwise be wasted–for example, the energy that dissipates during braking.The hydraulic system uses a pump motor and a tank, called [...]

The disposal of municipal solid waste (MSW) can lead to significant environmental burdens. The implementation of effective waste management practices, however, requires the ability to benchmark alternative systems from an environmental sustainability perspective. Existing metrics—such as recycling and generation rates, or the emissions of individual pollutants—often are not goal-oriented, are not readily comparable, and may [...]

The introduction of carbon capture and storage (CCS) technologies to waste management changes the landscape by increasing the capital costs and improving the environmental performance. The air emissions are significantly reduced, practically eliminated with oxygen combustion, as the capture of CO2 requires significant flue gas scrubbing. The introduction of CCS results in a net environmental [...]
