Energy and material productivity can be increased by the reuse and recycling of materials and products.
The latter part of Assumption 5 says that productivity of the former disposal process, in terms of material and labor input, is not greater than that of the latter process, but either material productivity or labor productivity is smaller in the former process.
In our experience, more than 20% of clinically isolated P. intermedia strains showed viscous material productivity under planktonic growth conditions [ 18].
Hydrodynamism in fact may affect sedimentation rates, larval settlement and, together with localized vertical nutrient fluxes and material retention, the productivity of the area [6], [9] [12].
Therefore, strong academic and industrial interest has been devoted to the integration of reaction and separation steps into one operation unit, which can save raw materials, increase the productivity of the process and save capital and operational costs.
It should be calculated in the same way as for resources, using the same energy intensity and/or natural productivity of the material that originated the waste.
Results indicated that the use of an energy storage material led to a larger productivity of distilled water and that the larger the concentration of the saline water the lower the productivity of the still.
Thus, in the case that productivity of a material input to the second process is relatively high compared to those to the fourth and the fifth processes, the price of waste is negative.
There is pressure exerted by healthcare institutions on investigators in terms of the productivity of scientific material.
