Meanders, named from the Menderes (historically known as the Maeander) River in Turkey, are most often formed in alluvial materials (stream-deposited sediments) and thus freely adjust their shapes and shift downstream according to the slope of the alluvial valley.
Microbial fermentation excels at converting sugars from low-cost raw materials streams into simple alcohols, acids, and other reactive intermediates that can be condensed into highly reduced, long and branched chain hydrocarbons and other industrially useful compounds.
Plastic-bag recycling rates remain low and in most normal schemes carrier bags are likely to be a contaminant rather than a valued material stream.
The Site Solution Provider, who handles all the plant's recycling, will then find the appropriate vendor for each specific material stream.
After one or more samples are taken from an amount of ore passing through a material stream such as a conveyor belt, the samples are reduced to quantities suitable for further analysis.
In a future where natural resources will become increasingly scarce and costly, take-back recycling systems — from the likes of Nike, H&M and Patagonia stores — offer brands a proprietary advantage by re-introducing textiles back into their material stream, thereby closing the loop.
"We realized we could build a business around people's desire to digitize and downsize their possessions as well as sell or trade the music they have," he said in a telephone interview, "and we also realized there was a valuable material stream here".
Table 1 shows the value of exergy for each material stream.
This study concentrates on heat and material stream integration for sustainable energy utilization in natural gas industrial parks.
This has consequently led to the importance of aluminium recycling to prevent the valuable material stream going to landfill.
Significant material stream on semiconductor substrate (without cooling it) results in complicated gold nanostructure growth mechanisms that differ from the known mechanisms.
