Organic wastes, such as fats, oils, and grease (FOG), are good substrates for biogas production because of their high methane yield potential. FOG are hydrolyzed to glycerol and long-chain fatty acids(LCFA), and the degradation of LCFA takes place through the β-oxidation pathway which has been reported as the rate-limiting step of the whole anaerobic digestion process. This paper reviews the sc...

As a green material, used date pits oil is increasingly utilized as inexpensive feedstock for ethyl ester (biodiesel) production. Waste date pits as a raw material are one of the highly produced agricultural wastes in Iran. This study investigated the effect of several procedure parameters including the ethanol/oil molar ratio, reaction temperature and amount of catalysts on the yield of the pr...

Τhis study focuses on the exploitation of food-industry wastes as a source for hydrogen production. The wastes which were used were out of date solid baby foods at seven different flavors (solid wastes) and a glucose-based syrup (liquid waste). Preliminary batch hydrogen experiments at mesophilic conditions and initial carbohydrates concentration of 5 g/L were performed to assess the hydrogen p...

Olive mill wastes (OMWs) are high-strength organic effluents, which upon disposal can degrade soil and water quality, negatively affecting aquatic and terrestrial ecosystems. The main purpose of this review paper is to provide an up-to-date knowledge concerning the microbial communities identified over the past 20 years in olive mill wastes using both culture-dependent and independent approache...

Biological treatment ofhazardous wastes has the potential for effective, practical, and economical remediation ofsome Superfund sites and other hazardous waste problems. Some biological hazardous waste treatments may also be applicable for preventing the occurrence of future hazardous waste sites. From a public health perspective, this technology may allow for the treatment of environmental haz...

Fruit and vegetables wastes not only have no commercial value, but also require expensive operations of removal and disposal, representing a significant cost for the manufacturers of plant products. However, this material may represent an important resource of commercially worth phyto-molecules endowed with various nutraceutical properties. In the present work, we have verified the possibility ...
