the purpose of this study was to evaluate the profitability of hatchery litter recycling into poultry feedstuff supplement. the data were collected in 2011 in 4 provinces, by direct interviewing of all hatcheries which used the hatchery litter drying machine. net present value (npv), benefit-cost ratio (bcr), and internal rate of return (irr) methods were applied for this analysis. in the studi...

Traditional methods for the disposal of Oil-Based Mud (OBM) drill cuttings have included pit burial or leaving the untreated cuttings scattered in-situ. Increasingly stringent regulations and increased environmental awareness have required new and improved disposal techniques. Scomi Equipment Inc, with over twenty one years Drilling Waste Management experience, has developed a system to remedia...

Based on the Systematic Layout Planning theory and the analysis of transfer stations’ technological processes, a layout optimization model for solid waste transfer and disposal stations was made. The operating units’ layout of the solid waste transfer and disposal stations was simulated and optimized using the genetic algorithm, which could achieve reasonable technological processes, the smalle...

The purpose of the project is to build a robotic arm, which can be controlled remotely over the internet, and to perform operations exhibiting higher accuracy with 6 degrees of freedom. The robotic arm uses IP network to receive data/commands from the user, over the internet, which are interpreted into proper instructions and then relayed to the controller. It reduces the human effort when used...

Introduction There is a significant and inevitable fact in Turkey which is the “sludge problem” generated from the wastewater treatment plants. There are many sludge disposal techniques currently applied in Turkey such as incineration, landfilling, composting, etc.; but the disposal of sludge with those conventional methods is difficult and expensive, often requiring over 50 per cent of the ope...

number of "municipal 'towns, in India, the methods of disposal of town"-wastes like night soil and katchra are highly insanitary and wasteful. The katchra dumping grounds and the night soil trenching grounds have often proved to be dangerous sources of fly breeding. For some years now, the compost method has been recommended as a satisfactory system of disposal of town refuse. It has proved to ...
