Estimation And Utilization Of Landfill Gas From Egyptian Municipal Wastes, A Case Study, Ali Habib, Ahmed A. Abdel-Rehim

Mechanical Engineering

Purpose

As the first Author had the chance to invest in landfill gas plant (EL Hammam plant) that flare approximately 1000 m3/hr. to generate electricity. Two critical question must be answered in order to proceed with the feasibility study. The three questions are:

1. 1- How many years this landfill gas emission will last?

2. 2- How much energy can be generated from one million ton if landfilled?

3. 3- How much CO2 in tons will be saved during the project life time?

Methods: Experimental method is used to determine BMP (Biochemical methane potential) ton CH4/ton waste. With

results we can know the …

Optimising The Performance Of Cement-Based Batteries, Aimee Byrne, Shane Barry, Niall Holmes Dr., Brian Norton

Articles

The development of a battery using different cement-based electrolytes to provide a low but potentially sustainable source of electricity is described. The current, voltage, and lifespan of batteries produced using different electrolyte additives, copper plate cathodes, and (usually) aluminium plate anodes were compared to identify the optimum design, components, and proportions to increase power output and longevity. Parameters examined include water/cement ratio, anode to cathode surface area ratio, electrode material, electrode spacing, and the effect of sand, aggregate, salts, carbon black, silica fume, and sodium silicate on the electrolyte. The results indicate that the greatest and longest lasting power can …
