“…The feasibility of using the UASB reactor for the digestion of vinasse has been demonstrated by many authors. Recently, van Haandel et al (2013) showed at pilot-scale, that a digestion rate of more than 40 kg-COD·m -3 ·d -1 can be maintained, whereas at full-scale, plants' rates of more than 20 kg-COD·m -3 ·d -1 have been observed (Weiland et al 2009). Knowing that anaerobic digestion leads to the generation of ¼ of a kg CH4 for each kg digested COD and that 1 kg CH4 in an efficient generator produces about 5 kWh of electric energy, a digestion rate of 20 kg-COD·m -3 ·d -1 leads to the production of 5 kg-CH4·m -3 ·d -1 , which can be transformed into 25kWh·m -3 ·d -1 , or a power generation potential of 1 kW·m -3 ; see also van Lier et al (2008).…”

The chemical energy in sugar cane is roughly equally divided into three fractions:(1) juice, the liquid part; (2) bagasse, the fibrous part of stalks; and (3) straw, the leaves and tops of the cane. So far, only the juice has productive use as a raw material for sugar and alcohol production. In this chapter, it is shown that anaerobic digestion can be applied to generate energy from sub-products, reducing the environmental impact of distilleries. Fermentation of cane juice leads to the generation of wastewater called vinasse, which is spread on the cane fields, using its nutrients. If vinasse is submitted to anaerobic digestion before using the nutrients, the produced biogas can generate electric energy at a rate of 45 kWh·tc -1 for a conversion efficiency of 40%. Presently, bagasse is burnt at sugar mills and distilleries for the generation of electric energy with boilers and steam turbines producing a 100 kWh·tc -1 at the maximum conversion efficiency of 16%. However, the application of anaerobic digestion to bagasse may increase the energy production potential to 150 kWh·tc -1 . Another 150 kWh·tc -1 can be added to the distillery's energy output from cane straw that generally remains on the fields when cane is harvested by anaerobic digestion as well. Currently, the production rate of sugar cane in Brazil is about 720 million tc·y -1 with a production potential electric energy of 124 TWh·y -1 from vinasse and bagasse, compared to a consumption of about 500 TWh·y -1 . Hence, this represents 25% of the national consumption.

“…One of the most prominent ways of the safe disposal of the majority of waste is composting which is an environmentally sound bioprocess of converting organic residual wastes into valuable products for farms (Pan et al 2012). Besides, if scaled up and industrialized, these products can also meet alternative fuel needs through sustainable waste management practices (Weiland et al 2009). Various microorganisms, their potential constituents that help in fast decomposition, biodegradation and bioconversion of crop residues and other valuable products are listed in Table 1.…”

Purpose Agricultural chemicals either used as nutrient inputs for soil fertility or pesticides are creating physicochemical and biological deterioration of the soils and disturbing the agro-ecosystems worldwide. Alarming concerns towards integrated agroecology demand for renewed interest in low-external input-based farming practices. These practices comprise strengthening of soil biological properties, recycling of inherent soil minerals and reuse of agricultural residual wastes. Methods We described approaches for the bioconversion of agricultural residual wastes into value-added compost. The process involves conversion of residual waste into raw compost followed by its fortification with beneficial decomposer microorganisms to produce quality fortified compost product. Finally, incubation of fortified compost with single or consortia of beneficial microorganisms like N-fixers, P-solubilizers or K-mobilizers and biocontrol agents further enriches compost to produce bioorganic products.

The Influence of the Pressure-Thermal Agglomeration Methods of Corn Bran on Their Selected Physicochemical Properties and Biogas Efficiency

The article presents the research made on the effects of methods of pressure-thermal agglomeration of corn bran, as well as the influence of processing parameters on selected physicochemical properties and biogas efficiency. Corn bran moistened to four levels of moisture content was used for the tests: 20%, 25%, 30% and 35% of dry matter. The pressure-thermal treatment was carried out with the use of a Brikol SJ25 pellet maker and a TS-45 single-screw extruder. In the tests of the extrusion-cooking process, three rotational speeds of the extruder screw were applied: 70, 90 and 110 rpm. The following characteristics were examined: efficiency of the extrusion-cooking and pelleting process, as well as the energy consumption. The water absorption index (WAI), the water solubility index (WSI), bulk density, kinetic strength, structure analysis by the ART/FTIR method, energy potential and the efficiency of cumulated biogas and cumulated methane per dry mass, as well as fresh mass and fresh organic matter and a series of microscopic pictures were completed. The analysis of the ATR/FTIR infrared spectra of the tested pelleted and extruded samples showed clear changes at the molecular level. Biogas production of extruded corn bran increased by several percent, as compared to untreated material.
