The New Solar Kiosk Model: A Sustainable Solution To Address The Uptake And Access Of Renewable Technologies To Create Energy Kiosks That Improve Women’S Income In Kiryandongo Refugee Settlement, Kiryandongo District, Northern Uganda., Musiimenta Joy Kellen

Regis University Student Publications (comprehensive collection)

This thesis was carried out in the Kiryandongo Refugee Settlement in Northern Uganda to test a new model to improve access to clean energy technologies in the refugee settlement. The settlement hosts more than seventy-five thousand refugees, including the Internally Displaced Persons (IDPs) from the Bududa landslides in Eastern Uganda. The literature review shows the challenges faced in the humanitarian sector. The challenge is met in providing lighting and improved cooking technologies to all refugees in settlements and camps globally. The refugees tend to cut down trees in the surrounding forest, and the wood is used for firewood to cook …

Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson

Master's Theses

Packed-bed digesters are an alternative to covered lagoon digesters for methane production and anaerobic treatment of dilute wastewaters such as dairy barn flush water. The physical media of packed-beds retain biofilms, often allowing increased treatment rates. Previous studies have evaluated several types of media for digestion of dilute wastewaters, but cost and media fouling have setback commercial development. A major operational cost has been effluent recirculation pumping.

In the present effort, a novel approach to anaerobic digestion of flush dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced …
