Universidad de Alicante posted this:Production of briquettes for energy recovery of furniture waste with polyurethane foamsThe Research Group "Waste, energy, environment and nanotechnology" (WEEN) from the University of Alicante has developed a new compact material and a production process of briquettes of furniture waste. This process makes it possible to carry out the management and the energy recovery of this waste, avoiding the environmental problems associated with its landfilling and also making it easier to transport, handle and store. The briquettes obtained, show physicochemical characteristics similar to the conventional and they have a high energy density being able to be used as fuel for thermal power plants or industrial boilers. Companies in the waste treatment sector and the furniture industry that are interested in commercial exploitation of this technology through licensing agreements and / or technical cooperation are sought.

It is a sustainable alternative to agroforestry crops currently used. The current technology stands out because it uses chitosan as the sole source of nutrients, and produces bioethanol in profitable, sustainable and environmentally friendly manner. The research group is looking for companies or investors partners interested in acquiring this technology for commercial exploitation.

Universidad de Cádiz posted this:New process for using beer bagasse (spent brewers grain) to obtain raw materials for the production of biofuelsCurrently, considerable quantities of lingo-cellulosic residues are generated continuously in many sectors of the agro-food industry. If these can be suitably processed, they are of great commercial interest to industry as potential raw materials for the production of biofuels and a variety of other high value-added products. The residual biomass of the agro-food industry typically has a high content in lipids, carbohydrates, proteins and other compounds of industrial interest. The only limitations to its use as a precursor of biofuel are the economic viability of the process for obtaining these precursors and their quality. One of the byproducts of special interest for this application is spent beer grain, also known as bagasse; given the existing lack of commercial value, this bagasse is widely available as a low-cost raw material. Currently, the principal application of bagasse is as feedstuff for livestock. In general, bagasse does not represent a source of income for breweries, and the reason why it is sold is to minimize the associated problems of waste management and disposal. The UCA research group on "Allelopathy in Higher Plants and Microorganisms" (FQM- 286) has developed an acid hydrolysis procedure whereby precursor materials for biofuels and other high -value-added products are obtained from beer bagasse. Its content in lipids and food fibre (equal to or more than 5% and 20%, dry weight, respectively), make it an ideal material for this application. This would represent a more attractive commercial outlet for many of the residues resulting from operations of the agro-food industry, and in particular, for beer bagasse. The object of the process is to obtain two different products. The first is an oil consisting mainly of the fats contained in the bagasse; the second is a substance rich in sugars or molasses. The oil is of interest as raw material for the production of biodiesel by the process of transesterification; the molasses can be employed as raw material for the production of bio-ethanol by means of fermentation. Molasses can also be formulated as sugar, after a crystallization process. The oil would be particularly useful for correcting the viscosity of biodiesel, thus achieving the optimum parameters for its use as biofuel. In outline, the process developed by the research group consists of a principal line, in which a series of operations take place for the conditioning of the bagasse, such as milling, extraction of lipids and the separation of the resulting solids. Downstream, this line divides into two secondary lines: in one line, for production of oils, the solvents from the prior extraction stage are separated out; in the other secondary line, for the production of molasses, an acid hydrolysis of the sugars is carried out. Another significant feature is that the optimum operating mode of the process is continuous operation, although batch loading is also accepted.
Universidad de Cádiz posted this:New procedure for the elimination of nutrients from waste waters by photobiotreatment with microalgasUCA researchers have developed a new process for the treatment of waste waters by using microalgae, specifically for the removal of nitrogen and phosphorus. This process is based on applying three fundamental findings made by the research group: • Before the microalgae start to grow, they are already consuming nitrogen and phosphorus when cultivated in waste waters. • The microalgae accumulate nutrients internally in such a way that the assimilation of nutrients commences before the growth phase, and at a rate that is considerably faster than the rate during the generation of biomass. • The initial elimination of nutrients prior to the growth of biomass takes place at a similar rate both in darkness and in the presence of light. To exploit this phenomenon, a procedure has been designed in which the two phases take place separately in two reactors: the first phase for elimination of nutrients from the waste water in darkness (known as ‘luxury uptake’) and the second for the growth of biomass under illumination. What this achieves is not only the efficient removal of the nutrients from the waste water but also, by means of a simple change of the mode of operation of the process, nutrients can be eliminated at night using the excess of biomass generated during daylight hours. To implement this advance, the research group has conceived a process for the separation of the biomass from the culture medium in both phases, by means of membrane technologies. The treatment plant can operate with cellular retention times very much longer than the hydraulic residence times. This, in turn, allows the same flow volumes of waste water to be treated in smaller reactors. • It enables waste waters to be treated at night without the need for a luminous phase. This cannot currently be done with the processes that employ existing photosynthetic organisms. • Simplicity of operation and reduction of costs in comparison with conventional technologies. It avoids the production of more solid residues, i.e. sludges, which require disposal. • The use of microalgae allows the treatment of waste waters with high levels of nitrogen and phosphorus but low content of organic matter (a characteristic of the waste waters of steelworks), since autotrophic organisms are involved. Thus the proposed process avoids the need to add organic matter from an external source, as is the case of other biological processes. • With the possibility of generating energy and capturing CO2, the biomass generated in the process represents value added in terms of energy consumption and environmental protection
