COMPOSTING TIME REDUCTION OF AGRO-INDUSTRIAL WASTES

Composting Agricultural and Industrial Wastes

Simulation of Carbon Dioxide Production during Composting of Agro-Wastes

Carbon dioxide production during composting of agro-waste can be taken as the indicator of rate, progress and termination of compost phenomenon and stabilization of organic matter, leading to a balanced compromise between complexity of mathematical model and extensive experimentation. Modeling and simulation of composting of agro-wastes based on experimentally measured carbon dioxide production...

Valorization of agro-industrial wastes towards the production of rhamnolipids.

In this work, oil mill wastewater (OMW), a residue generated during olive oil extraction, was evaluated as an inducer of rhamnolipid production. Using a medium containing as sole ingredients corn steep liquor (10%, v/v), sugarcane molasses (10%, w/v) and OMW (25%, v/v), Pseudomonas aeruginosa #112 produced 4.5 and 5.1g of rhamnolipid per liter in flasks and reactor, respectively, with critical ...

Use of Agro-Industrial Wastes in Solid-State Fermentation Processes

Large amount of wastes is generated every year from the industrial processing of agricultural raw materials. Most of these wastes are used as animal feed or burned as alternative for elimination. However, such wastes usually have a composition rich in sugars, minerals and proteins, and therefore, they should not be considered “wastes” but raw materials for other industrial processes. The presen...

Biotechnological Production of Xylitol from Agro-Industrial Wastes

Xylitol is a polyalcohol of five carbon atoms which is widely used in the food and chemical industry. Its interest is due to the sweetening power similar to that of sucrose. However, it has been shown that the use of xylitol as a sweetener is better due to its anticariogenecity, tooth rehardening and remineralization properties. It is suitable as sugar substitute for diabetics, and it limits th...
