This article proposes a procedure for finding a maximum-capacity path subject to a length constraint that excludes routes that may be exceedingly long to be considered environment-friendly and cost-effective.
Being a byproduct of industry, fly ash may be considered as environment friendly and low cost material for this purpose.
Biofuels converted from biomass, considered renewable, environment friendly and carbon neutral, will serve a more important function in the days to come.
Photoelectrochemical (PEC) cathodic protection is considered as an environment friendly method for metals anticorrosion.
Manganese oxides are reported to be considered as environment-friendly materials.
Phytases are also considered as environment-friendly enzymes, by avoiding the additional supply of exogenous phosphate and reducing the phosphate pollution from agricultural animal waste [11], [12].
CO2-based transcritical Rankine cycle (CTRC) is a promising technology for the waste heat recovery of an engine considering its safety and environment friendly characteristics, which also matchs the high temperature of the exhaust gas and satisfies the miniaturization demand of recovery systems.
BSD can be considered as efficient, low cost and environment friendly biosorbent for cadmium bioremediation, opening a new aspect of the economic value of shells of the freshwater snail B. bengalensis, apart from its value as cheap protein source.
We considered a friendly environment for both host growth and the enzyme reaction.
This environment friendly method (biological treatment) can be considered as an effective pretreatment to produce a high-quality chitin.
Although lignocellulosic sources are also considered as a promising feedstock for bioethanol production, there are several obstacles, such as the lack of an efficient, economical and environment friendly pretreatment process, that still needed to be overcome [ 6].
