Optimal conditions required the use of TBAF as the limiting reagent (0.9 equiv), with separation and several recycles to process the material.
Moreover the necessary cofactor nicotinamide adenine dinucleotide could easily be recycled to allow process operation under economic conditions.
However, the materials are sent for solid-state biogas production in a process similar to scenario 2. The water from the process is purified using macrofilters and reverse osmosis system and partially recycled to the process.
Most of the evaporation condensates are recycled to the process to reduce the use of fresh water.
The effluent from the ozone treatment is regarded as clean water and is recycled to the process partially or entirely depending on the scenario.
Macrofilters and reverse osmosis system are used for water purification, while 80% of the water is recycled to the process [ 17].
The removal of platinum group metals (PGMs) from dilute streams is essential due to their economic value and the increasing need to recycle process water.
The studies on the reuse of the TS-1 catalyst showed that it is very stable catalyst at the studied conditions and it can be recycled to the oxidation process at least three times.
Taiwan is building a factory to process and recycle the electronic waste generated by the island's consumers and its numerous technology companies.
However, to the best of our knowledge, scalable fabrication of reticulated polymer foams is limited to crosslinked, thermoset materials which are difficult to process and recycle.
Besides, the reserved La elements after acid treatment could be recycled to repeat the preparation process.
