Hydrogen has received wide attention in the last decade as a clean energy vector. The major advantage of energy from hydrogen is the zero carbon emissions, since the utilization of hydrogen, either via combustion or via fuel cells, results in pure water. At industrial scale, steam reformation of methane is currently the major hydrogen producing process. However recently, increasing interest has been paid on biological production of hydrogen gas. Indeed, biohydrogen generation from renewable biomass would reduce dependence on fossil fuel, decrease the carbon dioxide emissions and produce usable bioenergy. Biological production of hydrogen using anaerobic bacteria is an exciting and promising new area of technology development that offers the potential production of usable hydrogen from a variety of renewable resources such as carbohydrates from agriculture or agro-food industries. This biological system is called dark fermentation and the most interesting bacteria strains are Clostridium sp. The investigations carried out at CWBI involve selection and characterization of bacteria strains, optimization of the biotechnological process and design of highly efficient bioreactors. [less ▲]

Specimens of Miocene fossil wood from the Entre-Sambre-et-Meuse karsts (southern Belgium) were examined using physicochemical and biochemical techniques in order to understand the reasons for the exceptional preservation of these fossilized remains after 15 million years. Structural and chemical changes were assessed by comparing the structural features of the fossil samples with those of their modern counterpart, Metaseguoia. Solid state C-13 nuclear magnetic resonance (NMR) and microscopic analysis showed good preservation of the cellulose structure in the fossil wood from the Florennes peat deposit. Despite the substantial cellulose fraction available in the fossil tissue, an enzymatic degradation test and a biochemical methane potential assay showed that the fossil cellulose could not be degraded by cellulases and anaerobic microorganisms usually involved in the biodegradation of organic matter. Moreover, the cellulose structure (crystallinity and surface area) seemed to have no effect on cellulose biodegradability in these Miocene fossil wood samples. On the basis of our observations, we suggest that the presence of a modified lignin structure could greatly influence cellulose preservation/biodegradability. [less ▲]

This book describes the general guidelines for waste and landfill management, especially for developing countries. It contains four chapters. Ch. 1 describes waste management in developing countries (waste composition, production and harvesting modes; landfills characteristics; valorisation). Ch. 2 describes environmental aspects of waste management (biodegradation phenomenons; bioreactor-like landfill management; environmental impacts; investigation of biological activity of landfill in developing countries). Ch. 3 describes the general guidelines for controlled landfill (investigations for site location; landfill construction under wet and dry climates; landfill management and monitoring; financial aspects). Ch. 4 synthesizes the social and economical aspects of waste and landfill management and describes some best practices for harvesting, valorisation, and disposal of MSW) [less ▲]

As there is a constant need to assess the biodegradation potential of refuse disposed of in landfills, we have developed a method to evaluate the biodegradability of cellulosic compounds (cellulose and hemicellulose) in municipal solid waste. This test is based on the quantification of monosaccharids released after the hydrolysis of solid waste samples with an optimised enzyme preparation containing commercially available cellulases and hemicellulases. We show that the amounts of monosaccharids could be related to the biodegradability of the cellulosic material contained in the samples. This enzymatic cellulose degradation test was assayed on 26 samples originating from two Belgian landfills and collected at different depths. As results correlated well with those obtained with a classical biochemical methane potential assay, this new and rapid test is sufficiently reliable to evaluate cellulose bioavailability in waste samples.

We recently developed a new and rapid method to evaluate the biological reactivity of cellulose in Municipal Solid Waste (MSW). This test is based on the enzymatic hydrolysis of cellulose in MSW and can be related to the digestibility of this polymer in MSW. In this work, we showed that the enzymatic cellulose degradation test (ECD) correlated well with a Biochemical Methane Potential (BMP) assay so that the ECD test can be reliably applied to estimate cellulose bioavailability in various waste samples. These tests have also been used to evaluate the influence of some important parameters that could affect the extent and the rate of cellulose degradation in waste. It appeared that cellulose enzymatic hydrolysis is related to the moisture content but no clear relationship could be established with the cellulose content. Moreover, it is shown that acetic acid produced by the anaerobic degradation of organic matter, and responsible for high COD in young leachates, may slow down or inhibit the enzymatic hydrolysis step and the methanogenesis.

This paper presents the results of the investigation of the biological activity that takes place in three municipal solid waste landfills (MSW landfills) situated in different regions of two dry climate in Tunisia. Since the climatic water balance is negative (potential evapotranspiration being 1.5 to 5 times higher than rainfall), it has often been considered that this kind of landfill has neither environmental impact nor efficient biological activity. However, the three landfills revealed a biological activity with biogas often containing more than 60 percent of methane. Indeed, the upper waste layer that was effectively dry (dry weight from 85 to 98%), the core of refuse contained between 35 and 65% of dry matter. In some boreholes, the produced gases periodically expelled leachates like small geysers. Therefore, the results assess that landfill management in countries with dry climate should be considered with adapted technologies, not necessary the same as under temperate or humid climates.
