Many countries are enacting policy measures in support of biofuels and for green-house-gas emissions reduction in the transport sector. The most important policy measures at the time of writing for the EU and the USA are given below. For an overview of worldwide policy support measures for biofuels, see the EC (2006) the IEA (2006b) and Martinot el al. (2006).

Psia, (b) co-current CO2 rinse at that pressure with recycle of effluent gas as feed, (c) counter-current evacuation to - 2.5 Psia with simultaneous steam pui e, and (d) counter-current pressurization with a part of CO2 depleted product gas from step (a). The effluent gas from step (c) is partly used as the purge gas in step (b) after recompression, and the balance is withdrawn as the recovered CO2 product gas. The inert gas and CO2 recoveries from the feed gas are, respectively, - 100 and 78% [21]. This application may be attractive for green house gas emission control (CO2 sequestration from a hot flue gas or CO2 removal from combustion gases for power generation). 

The solar-thermal process is enviromnentally friendly. The most environmentally friendly option is when selling carbon black into the tire carbon black market as the energy and pollution associated with normal carbon black production are avoided. If carbon is fed to a carbon conversion fuel cell, the total green house gas emissions are still 60% of those of a steam reformer and the bulk of the released CO2 is in a pure form so it can be easily sequestered.

Manufacturers, users, and nongovernmental organizations (NGO) are constantly demanding environmental impact data for the materials used in the production of various items. Environmental impact data, normally include items such as total energy used, green house gas emissions (GHG), toxic elements released, biological... 

Methods of waste reduction, waste reuse and recycling are the preferred options when managing waste. There are many environmental benefits that can be derived from the use of these methods. They reduce or prevent green house gas emissions, reduce the release of pollutants, conserve resources, save energy and reduce the demand for waste treatment technology and landfill space. Therefore it is advisable that these methods be adopted and incorporated as part of the waste management plan. This chapter will highlight the use of clays in such processes. 

Heat recovered from process off-gas as high-pressure steam can be used for drying the feed material or for electricity generation, reducing the demand for electricity from power plants and minimizing green house gas emissions. 

Scenario analysis is using the concept of possible future through a set of pathways, for example, the result of status-quo energy consumption in the green house gas emission in 2030 and a change in pathways to understand the likely future scenarios. If some structural interventions are being considered by the planners, the result of such interventions ean be considered to develop a likely scenario in the future.

The factors that are generally considered in a full life-cycle assessment of a fibre include energy use, green house gas emissions, water use, land use, toxicity to humans and ecosystems, useful life of the product and final disposal. 

These regeneration schemes allow simultaneous production of H2 and CO2 by the process with high purity and recovery for both components. Production of a CO2 by product from SMROG is a valuable feature of the Gemini process because the CO2 can be sequestered after necessary compression to minimize the green house gas emission to the atmosphere. The amount of CO2 emission from a 100 MMSCFD H2 PSA plant is 1500 tons per day.
