BACKGROUND Biohydrogen production through dark fermentation using organic waste as a substrate has gained increasing attention in recent years, mostly because of the economic advantages of coupling renewable, clean energy production with biological waste treatment. An ideal approach is the use of selected microbial inocula that are able to degrade complex organic substrates with simultaneous bi...

A pilot-scale study was undertaken to evaluate alternatives to the solid waste management of a Central American municipal market located in Estelí, Nicaragua. The municipal solid waste from the local market is the second largest contributor to the municipal solid waste (MSW) stream. Waste from the market without any previous sorting or treatment is open dumped. The options evaluated in this stu...

The cities are facing illegal dumping of municipal solid waste (MSW) because the waste collection facilities do not cover the entire population. Furthermore, this sector is poorly developed in small towns or villages annexed to administrative territory units (ATU) of cities , MSW are disposed in open dumps polluting the local environment. This paper analyzes on the one hand the urban disparitie...

Solid waste collection, transfer and transportation (SWCTT) is a fundamental component of solid waste management systems that contributes to both the costs and environmental emissions associated with managing solid waste. The objective of this study is to project the fuel consumption and fuel costs of SWCTT in Tehran from 2018 to 2032. A further objective is to evaluate the air pollutant emissi...
