The role of green supply chain management on organizational productivity and excellence

Regarding the competitive market at present age and the importance of environmental problems, green supply chain management is converted into one of the problems for the organizations and companies. Green supply chain management will be useful in respect of the improvement of environmental performance of advantage (benefit) supply chain and will be followed by many benefits such as saving in energy resources, decreasing the pollutants, omission or decreasing the wastes, value creation (production) for the customers and ultimately, and finally improving productivity for the companies and organizations. This research addressed to supply chain and its effect on the organizational elevation and productivity. Statistical population of the present research consists of the staffs of Fooladin Zob Amol Company who are 28 persons. Some questions based on the questionnaire are available for the staff of this company and out of this number, 19 persons answered the questionnaire. The collected data were statistically analyzed by SPSS software and T-test was used for this reason. Research result represents that all of the components implemented in the questionnaire, have a direct relationship with the organizational excellence and productivity in Fooladin Zob Amol Company

Poultry litter angle of wall friction

Dependence on chemical fertilizer is continually increasing.  Continual increasing of using chemical fertilizer causes nature pollution (e.g. water contamination).  This has led researchers to aggressively investigate renewable fertilizer resources and biomass to produce organic crops and reduced wastage.  Poultry litter is a bulk solid and biomass feed stocks. The angle of wall friction (AWF) is a critical factor in designing and constructing suitable equipment for pelletizing.  The results of this study showed that the simple effects of the moisture content (M) and surface types (S) as well as interaction of the S × particle size (P) and S × M were significant (

The effect of moisture content, particle size and consolidation stress on flow properties of vermicompost

 Physical properties of granular solids are essential to design appropriate, efficient, and economic bulk solids handling and storage equipment.  Flow of vermicompost is often restricted by caking and bridging, which occurs during transportation and storage.  This problem could be due to a number of factors including storage moisture, temperature, particle size, and consolidation stress.  There is lack of study on the effect of the mention factors simultaneously on flow index, cohesive strength and angle of internal friction of vermicompost.  The aims of this work were to discuss the primary factors affecting flowability of vermicompost as granular solids and powders, as well as using shear testing methodologies for this biomass material.  The experiments were conducted on samples selected from a wormy culture farm, Karaj, Iran, by Jenike’s shear cell technique.  The data was statistically analyzed using the three factors completely randomized design to study the effects of particle size, moisture content and consolidation stress on vermicompost flow properties.  The results showed that a significant difference between the flow index values at different stress levels.  Greater moisture content and smaller particle size caused poor flowability of vermicompost.  Increasing the moisture content and decreasing the particle size from 1.18 to 0.3 mm, the vermicompost reduced its flowability from free flowing at moisture content of 25% (w.b.) to cohesive at moisture content of 35% (w.b.).   Keywords: biomass flowability, flow index, shear test, vermicompost
