Due to the existing pressure for a more rational use of the water, many public managers and industries have to re-think/adapt their processes towards a more circular approach. Such pressure is even more critical in the Rio Doce region, Minas Gerais, due to the large environmental accident occurred in 2015. Cenibra (pulp mill) is an example of such industries due to the fact that it is situated in the river basin and that it has a water demanding process. The current proposal is meant as an academic and engineering study to propose possible solutions to decrease the total water consumption of the mill and, thus, decrease the total stress on the Rio Doce basin. The work will be divided in three working packages, namely: (i) evaluation (modelling) of the mill process and water balance (ii) application and operation of a pilot scale wastewater treatment plant (iii) analysis of the impacts caused by the improvement of the process. The second work package will also be conducted (in parallel) with a lab scale setup in The Netherlands to allow fast adjustments and broaden evaluation of the setup/process performance. The actions will focus on reducing the mill total water consumption in 20%.
Tropisch hardhout voor bouw en interieur veroorzaakt veel schade aan kwetsbare tropische bossen (ontbossing, nutriënten-onttrekking, onvervangbare schade aan biodiversiteit en dierenleven, onwenselijke werkomstandigheden lokale arbeiders). Bamboe lijkt een goed alternatief, maar wordt nog voornamelijk geïmporteerd uit Azië met een negatieve impact op de footprint van bamboeproducten. Europees geteelde bamboe zou, als een bruikbaar alternatief voor de Aziatische bamboe en tropische hardhoutsoorten, de negatieve footprint aanzienlijk kunnen beperken. Het Centre of Expertise Future Makers van ArtEZ hogeschool voor de kunsten onderzoekt samen met bamboeproducent Bamboologic en ontwerper Floor Beckering of de in Portugal geproduceerde bamboe voldoende kwaliteit kan krijgen op basis van het natuurlijke bindmateriaal lignine. Belangrijke partner hierbij is Stichting Hout Research (SHR) die veel kennis heeft op het gebied van Aziatische bamboe en zeer geïnteresseerd is om de kwaliteiten van Europees bamboehout te testen en mee te denken over interessante toepassingsgebieden. Masterstudenten van Future Makers vaste onderzoekspartner Wageningen Universiteit & Research zullen deelonderzoeken voor hun rekening nemen. Het project past binnen de ambities ‘Nederland Circulair in 2050’ en sluit aan op de transitieagenda’s van ‘Bouw’ en ‘Consumptiegoederen, vooral waar het gaat om duurzame houttoepassingen in bouw, interieurafwerking en meubels. De uitkomsten van het onderzoek zijn dan ook relevant voor de gehele bouw- en interieursector. Deze KIEM-aanvraag hoopt een eerste aanzet te zijn in vervolgonderzoek naar mogelijke productie en implementatie van bamboe en bamboeproducten.
Synthetic ultra-black (UB) materials, which demonstrate exceptionally high absorbance (>99%) of visible light incident on their surface, are currently used as coatings in photovoltaic cells and numerous other applications. Most commercially available UB coatings are based on an array of carbon nanotubes, which are produced at relatively high temperature and result in numerous by-products. In addition, UB nanotube coatings require harsh application conditions and are very susceptible to abrasion. As a result, these coatings are currently obtained using a manufacturing process with relatively high costs, high energy consumption and low sustainability. Interestingly, an UB coating based on a biologically derived pigment could provide a cheaper and more sustainable alternative. Specifically, GLO Biotics proposes to create UB pigment by taking a bio-mimetic approach and replicate structures found in UB deep-sea fish. A recent study[1] has actually shown that specific fish have melanosomes in their skin with particular dimensions that allow absorption of up to 99.9% of incident light. In addition to this, recent advances in bacterial engineering have demonstrated that it is possible to create bacteria-derived melanin particles with very similar dimensions to the melanosomes in aforementioned fish. During this project, the consortium partners will combine both scientific observations in an attempt to provide the proof-of-concept for developing an ultra-black coating using bacteria-derived melanin particles as bio-based, sustainable pigment. For this, Zuyd University of Applied Sciences (Zuyd) and Maastricht University (UM) collaborate with GLO Biotics in the development of the innovative ‘BLACKTERIA’ UB coating technology. The partners will attempt at engineering an E. coli expression system and adapt its growth in order to produce melanin particles of desired dimensions. In addition, UM will utilize their expertise in industrial coating research to provide input for experimental set-up and the development of a desired UB coating using the bacteria-derived melanin particles as pigment.
