Energy harvesting by waste acid/base neutralization via bipolar membrane reverse electrodialysis

2020

Bipolar Membrane Reverse Electrodialysis (BMRED) can be used to produce electricity exploiting acid-base neutralization, thus representing a valuable route in reusing waste streams. The present work investigates the performance of a lab-scale BMRED module under several operating conditions. By feeding the stack with 1 M HCl and NaOH streams, a maximum power density of ~17 W m−2 was obtained at 100 A m−2 with a 10-triplet stack with a flow velocity of 1 cm s−1, while an energy density of ~10 kWh m−3 acid could be extracted by a complete neutralization. Parasitic currents along feed and drain manifolds significantly affected the performance of the stack when equipped with a higher number of t…

Urban Waste As Resource For Sustainable Environment

2013

The emerging model of waste disposal, develops an integrated approach based on waste reduction, selection, recycling, energy recovery and residual use of landfill. Here we discuss the fundamentals of a proper planning of waste disposal system, specially the thermal recovery, the integration and the methodological approach, either from the environmental and economic point of view. The growing demand for energy, the resulting environmental problems due to satisfy the demand for energy and the complex-economic system, necessitate the study of new technologies such as energy from municipal solid waste (MSW) obtaining as a result of decrease huge mass of solid waste to sanitary landifill and emi…
