Municipal Waste to Energy - Case Study
After viewing the Dominator depackaging system at one of our previous installations a customer decided that this system would be perfect to suit their needs. Municipal waste is loading into an intake hopper where the waste begins the conditioning process, this waste is then augured to the Dominator depackager where plastic is removed from the food waste. The food waste is then pumped into a ...

Optimum organic loading rate for semi-continuous operation of an anaerobic process for biogas production from Jatropha curcas seed cake
This paper reports on biogas production by anaerobic digestion of Jatropha curcas seed cake in semi continuous flow at 30°C, focusing on increasing the organic loading rate (OLR) of seed cake by investigating levels of 1.25, 1.67, 2.5, 3.33 and 5 kg Chemical Oxygen Demand (COD)/m³ day. Reactors were fed at flow rates of 125, 167, 250, 333 and 500 ml/day, yielding Hydraulic Retention Times (HRTs) ...

Enhancement of hydrogen production from Kitchen Waste using heat treated anaerobic biogas plant slurry with pH control
Hydrogen is found to be a clean energy source; biohydrogen has been researched in recent years. Anaerobic Digestion of Kitchen Waste (KW) for hydrogen production was performed in lab scale reactors, using heat-treated anaerobically digested biogas plant slurry. The biogas plant slurry was given heat treatment at varying temperatures ranging from 70 to 100 ° C for 15 min. Enhancement of hydrogen ...

Converting Waste to Energy - Case Study
Waste management is a necessity wherever people live, but traditionally waste is viewed as a problem, something that pollutes and needs reducing or mitigating. What if this mindset could be changed such that we value our waste as a source of bioenergy? Waste contains significant quantities of energy and, if we could harness this close to where the waste is generated and convert it to a useable ...

Project - MEKKER - Valorization of food waste through the production of chemicals via microbial technology
Project In a rising demand of new technologies, the focus shifts from dry to rather wet anaerobic fermentation of waste streams. These waste streams are typically the vegetables & fruit (GF) fraction. For these organic waste streams, the DRANCO technology cannot be used because of the low dry weight percentage. This shift towards the usage of a wet anaerobic digestion is a preferrable choice, ...

Turning waste into power
Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...
