As part of the theme 13 and 14, our group have to realize a project in the field of the renewable energy. This project consist of the design of a bio-digester for the canteen of Zernikeplein. Gert Hofstede is our client. To produce energy, a bio-digester uses the anaerobic digestion, which is made of many processes where bacteria break down biodegradable material in the absence of oxygen. The organic garbage, like kitchen waste, are fed into the bio-digester with a small amount of water. We designed the bio-digester according to the specifications of our client, our teachers, some companies we met, and our own ideas. The bio-digester is built by ourselves, even if we ordered some parts of it. Therefore, this project made us creative because we had to design and to build. It also permitted us to use our skills gained the previous years of our studies.
The increase in renewable energy sources will require an increase in the operational flexibility of the grid, due to the intermittent nature of these sources. This can be achieved for the gas and the electricity grid, which are integrated by means of power-to-gas and vice versa, by applying gas and other energy storages. Because renewables are applied on a decentralized scale level and syngas and biogas are produced at relatively low pressures, we study the application of a decentralized (bio)gas storage system combined withMicro Turbine Technology (MTT), Compressed Air Energy Storage (CAES) and Thermal Energy Storage (TES) units, which are designed to optimize energy efficiency.In this study we answer the following research questions:a. What is the techno-economical feasibilty of applying a decentralized (bio)gas storage with a MTT/CAES/TES system to balance the integrated renewable energy network?b. How should the decentralized (bio)gas storage with MTT/CAES/TES system be designed, so that the energy efficient application in such networks is optimized?Note that:c. We verify the calculations for the small scale MTT unit with measurements on our proof-of-principle set-up of part of the system that includes two MTTs in parallel.Based on wind speed, irradiance patterns and electricity and heat demand patterns for a case of 100 households, we found the optimum dimensions for the decentralized (bio)gas storage based on guaranteed supply. We concluded that a decentralized (bio)gas storage of 85 000 Nm3 was needed to provide the heat demand. LNG was the most energy efficient storage technology for such dimensions.The use of (bio)gas directly in a CHP (P/Q ratio = 2/3) that was mainly heat driven, resulted in a continuous overproduction of electricity due to the dominant heat demand of the 100 households in the Netherlands.This does not leave any room for the increase in the application of PV and wind generators, nor is there a purpose for electricity storage.For that reason we will further investigate the application of a decentralized (bio)gas storage with MTT/CAES/TES as a solution to balance a renewable integrated network. Using an MTT in the system offers a more useful P/Q ratio for households of 1/5.
Verschillende maatschappelijke veranderingen dwingen de bouwbranche tot innovaties. Ondanks de potentie op het vlak van circulariteit en duurzaamheid van 3D-printen met kunststoffen kent deze technologie nog nauwelijks toepassingen in de bouw. Redenen hiervoor zijn achterblijvende materiaaleigenschappen en het verschil in cultuur tussen de bouwwereld en kunststofverwerkende industrie. Het bedrijf Phidias, richt zich op innovatieve en creatieve vastgoedconcepten. Samen met Zuyd Hogeschool (Zuyd) willen zij onderzoek doen naar het printen van bouwelementen waarbij de meerwaarde van 3D-printen wordt gezien in het combineren van materiaaleigenschappen. Zuyd heeft afgelopen jaren veel onderzoek gedaan naar het ontwikkelen van materialen voor 3D-printen (o.a. 2014-01-96 PRO). De volgende fase is de opgedane kennis toe te passen voor specifieke applicaties, in dit geval om de vraag van het MKB bedrijf Phidias te beantwoorden. Vanuit een ander MKB-bedrijf, MaukCC, ontwikkelaar van 3D printers, komt de vraag om de afstemming tussen materialen en hardware te optimaliseren. De combinatie van beide vragen uit het werkveld en de expertise bij Zuyd heeft geleid tot dit projectvoorstel. In deze pilotstudie ligt de focus voornamelijk op het 3D printen van één specifiek bouwkundig element met meerdere eigenschappen (bouwfysisch en constructief). De combinatie van eigenschappen wordt verkregen door gebruik te maken van twee (biobased) kunststoffen waarbij tevens een variatie wordt aangebracht in de geprinte structuren. Op deze manier kunnen grondstoffen worden gespaard. Het onderzoek sluit aan bij twee zwaartepunten van Zuyd, namelijk “Transitie naar een duurzaam gebouwde omgeving” en “Life science & materials”. De interdisciplinaire aanpak, op het grensvlak van de lectoraten “Material Sciences” (Gino van Strydonck) en “Sustainable Energy in the Built Environment” (Zeger Vroon) staat garant voor innovatief onderzoek. Integratie van onderwijs en onderzoek vindt plaats door studenten samen met een coach (docent) en ervaren professional aan dit onderzoek te laten werken in Communities for Development (CfD’s).
The textile and clothing sector belongs to the world’s biggest economic activities. Producing textiles is highly energy-, water- and chemical-intensive and consequently the textile industry has a strong impact on environment and is regarded as the second greatest polluter of clean water. The European textile industry has taken significant steps taken in developing sustainable manufacturing processes and materials for example in water treatment and the development of biobased and recycled fibres. However, the large amount of harmful and toxic chemicals necessary, especially the synthetic colourants, i.e. the pigments and dyes used to colour the textile fibres and fabrics remains a serious concern. The limited range of alternative natural colourants that is available often fail the desired intensity and light stability and also are not provided at the affordable cost . The industrial partners and the branch organisations Modint and Contactgroep Textiel are actively searching for sustainable alternatives and have approached Avans to assist in the development of the colourants which led to the project Beauti-Fully Biobased Fibres project proposal. The objective of the Beauti-Fully Biobased Fibres project is to develop sustainable, renewable colourants with improved light fastness and colour intensity for colouration of (biobased) man-made textile fibres Avans University of Applied Science, Zuyd University of Applied Sciences, Wageningen University & Research, Maastricht University and representatives from the textile industry will actively collaborate in the project. Specific approaches have been identified which build on knowledge developed by the knowledge partners in earlier projects. These will now be used for designing sustainable, renewable colourants with the improved quality aspects of light fastness and intensity as required in the textile industry. The selected approaches include refining natural extracts, encapsulation and novel chemical modification of nano-particle surfaces with chromophores.
