Western-European consumers have become not only more demanding on product availability in retail outlets but also on other food attributes such as quality, integrity, and safety. When (re)designing food supply-chain networks, from a logistics point of view, one has to consider these demands next to traditional efficiency and responsiveness requirements. The concept ‘quality controlled logistics’ (QCL) hypothesizes that if product quality in each step of the supply chain can be predicted in advance, goods flows can be controlled in a pro-active manner and better chain designs can be established resulting in higher product availability, constant quality, and less product losses. The paper discusses opportunities of using real-time product quality information for improvement of the design and management of ‘AgriFood Supply Chain Networks’, and presents a preliminary diagnostic instrument for assessment of ‘critical quality’ and ‘logistics control’ points in the supply chain network. Results of a tomato-chain case illustrate the added value of the QCL concept for identifying improvement opportunities in the supply chain as to increase both product availability and quality. Future research aims for the further development of the diagnostic instrument and the quantification of costs and benefits of QCL scenarios.

Binnen het projectonderwijs wordt nog vaak drooggezwommen. Enerzijds door de verstrekte projectopdrachten anderzijds door de suboptimalisatie van oplossingen. Deze zijn namelijk sterk afhankelijk van de verbonden modules en docenten. In de praktijk zijn de oplossingen echter altijd een afweging van tijd, geld en kwaliteit. Onze Human Engineers leren om daar op een goede manier mee om te gaan. Dit door de integratiemodule Integrated Product Development (IPD). IPD is een multidisciplinair project waarbij studenten van verschillende Fontys Instituten werken aan de commercikle en technische uitwerking van een bedrijfsopdracht. Marktonderzoek, doelgroep bepaling en productspecificatie zijn een vast onderdeel van een IPD project evenals het ontwerpen en bouwen van een prototype en het financieel onderbouwen van een Go/NO go advies aan de ondernemer. Het project vindt plaats in het laatste onderwijssemester, net vssr het afstuderen en is dus te zien als een open project met een bedrijf als opdrachtgever. De Human Engineering studenten zijn in deze projecten de verbindende schakel. De specialisten in de projectgroepen, de technische studenten, willen nogal eens zoeken naar mooie oplossingen vooral in technische zin. Daarbij gaan ze vaak volledig voorbij aan het belang van de ondernemer (winst maken) en het belang van de klant (kwaliteit en bedieningsgemak). Ook het projectwerk heeft een enorme sprong vooruit gemaakt door het team uit te breiden met Human Engineers. De Human Engineering studenten focussen vooral ook op het halen van targets (kosten) en deadlines (tijd), het maken en nakomen van afspraken en de communicatie binnen de groep en naar buiten toe (ondernemer en klant). Huidige studenten en alumni geven aan dat het project zeer realistisch is en dat het vergelijkbaar is met problemen die ze in hun werk tegen komen. Zeker blijven doen is hun advies. Organisatorisch vergt het wel een en ander omdat er bijvoorbeeld afstemming dient te komen tussen de verschillende instituten met betrekking tot: beoordeling van de studenten, afstemmen van lesroosters en vergoeding voor docenten. Ook het onderhouden van bedrijfsrelaties om bijvoorbeeld aan de opdrachten te komen blijft een moeilijke, tijdrovende zaak.

There are lots of definitions of quality, and also of quality in education. Garvin (1984)discerns five approaches: the transcendental approach, the product-oriented approach, the customeroriented approach, the manufacturing-oriented approach and the value-for-money approach. Harvey and Green (1993) give five interrelated concepts of quality as: exceptional, perfection (or consistency), fitness for purpose, value for money and transformative. A new definition of quality is needed to explain recent quality issues in higher education. This article describes a quality concept with four constituents: object, standard, subject and values. The article elaborates on the values. Four value systems derived from Beck and Cowan (1996) are transformed into four value systems on quality and quality management: control, continuous improvement, commitment and breakthrough. These value systems make it possible to explain some recent developments in quality management in higher education.

Goal: In 2030 the availability of high quality and fit-for-purpose recycled plastics has been significantly increased by implementation of InReP’s main result: Development of technologies in sorting, mechanical and chemical recycling that make high quality recycled plastics available for the two dominating polymer types; polyolefins (PE/PP) and PET. Results: Our integrated approach in the recycling of plastics will result in systemic (R1) and technological solutions for sorting & washing of plastic waste (R2), mechanical (R3) and chemical recycling (R4, R6) and upcycling (R5, R7) of polyolefins (PE & PP) and polyesters (PET). The obtained knowledge on the production of high quality recycled plastics can easily be transferred to the recycling of other plastic waste streams. Furthermore, our project aims to progress several processes (optimized sorting and washing, mechanical recycling of PP/PE, glycolysis of PET, naphtha from PP/PE and preparation of valuable monomers from PP/PET) to prototype and/or improved performance at existing pilot facilities. Our initiative will boost the attractiveness of recycling, contribute to the circular transition (technical, social, economic), increase the competitiveness of companies involved within the consortium and encourage academic research and education within this field.
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%.
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.
