In this masterclass, HAS lector Rob Bakker and teacher-researcher Annelies Verspeek-van der Stelt explain wat is the definition of food waste, what is a food waste hotspot, en what entals food waste measurement en monitoring. Examples are given of food waste measurement at HAS green academy.

In this masterclass, Fontys teacher-researcher Jos Pieterse explains human behaviour concerning creating food waste (throwing away good food) using behaviour models such as Dynamo and Triade. Presented are also a list of questions that can be used to assess a person’s willingness to change his/her behaviour.

In this masterclass, Toine Timmermans, director Stichting Samen tegen Voedselverspilling (Foundation Together against Food Waste), explains what is food waste , what the effects of food waste are on our environment, how much we waste and what we can do about it. He also gives many examples how we can reduce food waste.

The valorization of biowaste, by exploiting side stream compounds as feedstock for the sustainable production of bio-based materials, is a key step towards a more circular economy. In this regard, chitin is as an abundant resource which is accessible as a waste compound of the seafood industry. From a commercial perspective, chitin is chemically converted into chitosan, which has multiple industrial applications. Although the potential of chitin has long been established, the majority of seafood waste containing chitin is still left unused. In addition, current processes which convert chitin into chitosan are sub-optimal and have a significant impact on the environment. As a result, there is a need for the development of innovative methods producing bio-based products from chitin. This project wants to contribute to these challenges by performing a feasibility study which demonstrates the microbial bioconversion of chitin to polyhydroxyalkanoates (PHAs). Specifically, the consortium will attempt to cultivate and engineer a recently discovered bacterium Chi5, so that it becomes able to directly produce PHAs from chitin present in solid shrimp shell waste. If successful, this project will provide a proof-of-concept for a versatile microbial production platform which can contribute to: i) the valorization of biowaste from the seafood industry, ii) the efficient utilization of chitin as feedstock, iii) the sustainable and (potentially low-cost) production of PHAs. The project consortium is composed of: i) Van Belzen B.V., a Dutch shrimp trading company which are highly interested in the valorization of their waste streams, hereby making their business model more profitable and sustainable. ii) AMIBM, which have recently isolated and characterized the Chi5 marine-based chitinolytic bacterium and iii) Zuyd, which will link aforementioned partners with students in creating a novel collaboration which will stimulate the development of students and the translation of academic knowledge to a feasible application technology for SME’s.
De horeca-sector en het toerisme worden zwaar getroffen door de huidige crisis. Omzetschade is historisch groot; tegelijkertijd zijn er vanuit de praktijk veel vragen over hoe nieuwe werkwijzen moeten worden ontwikkeld en toegepast. Voor onze sector voorziet onderzoek in het kader van de Impuls-regeling daarom onmiskenbaar in een grote maatschappelijke behoefte. Hotelschool The Hague (HTH) zet strategisch in op het behoud en de versterking van praktijkgericht onderzoek en op het onderzoekend vermogen van haar studenten. Onderzoekend vermogen is, voor toekomstige afstudeerders in een snel veranderende arbeidsmarkt, door de HTH gedefinieerd als cruciale kernvaardigheid. In dit kader zijn recent de onderwijs- en onderzoeksprogramma’s van de HTH hervormd rond de principes van Design Oriented Research. Door de COVID-19 crisis is de continuïteit van het praktijkgericht onderzoek van de HTH, misschien nog wel meer dan bij brede hogescholen onder druk komen te staan. Met het hier voorgestelde Impuls 2020 bestedingsplan wil HTH de onderzoeksfunctie van haar praktische outlets — haar schoolrestaurants en -hotels— verder versterken zodat deze kunnen worden ingericht en gebruikt als ‘test-beds’ of HTH Labs. De schoolrestaurants en -hotels worden hiermee een faciliteit voor experimenteel, praktijkgericht onderzoek waar in commerciële bedrijven vaak geen mogelijkheid voor is. Dit Impuls 2020 voorstel behelst de visievorming voor de HTH Labs en de netwerkvorming met andere kennisinstellingen en met bedrijven als beoogde afnemers van de kennis die in de Labs ontwikkeld zal worden. Het voorstel voorziet tevens in de uitvoering van 3 pilotstudies die de mogelijkheden van de HTH Labs inzichtelijk maken voor het bedrijfsleven. De Impuls financiering zal uiteindelijk resulteren in een operationele onderzoeksfaciliteit in de schoolrestaurants en -hotels van de HTH, en in drie onderzoeksrapporten met bijbehorende disseminatie-activiteiten.
The expanding world’s population challenges the way we produce and supply food. The ever-increasing production of food and its subsequent generated biomass forms immense risks to the environment and, eventually, public health. Aside from developing innovative food production methods (hydroponics, non-toxic pesticides, resistant species), the generation of waste biomass remains a challenge. Large volumes of food waste are processed in animal food, biofuel or used as a composting source, while these by-products are valuable sources of bioactive compounds (BACs). The processing of fruits and vegetables generates a variety of biomass such as peels, seeds and pulp that contain high-value compounds such as polyphenols. These BACs are implemented in pharmaceutical products or food supplements for their beneficial influence on human health, such as antioxidant or anti-inflammatory properties. The valorization and extraction of these compounds originating from agricultural waste streams is a key strategy for recycling and reusing food waste and, subsequently, reducing the environmental impact caused by waste streams. Additionally, the ability to further process food waste into valuable compounds can provide an extra source of income for the agricultural sector, supporting local economies. Local pharmaceutical companies are interested in developing methods to extract BACs from local sources since the current market is strongly dependent on the Asian market. Phytopharma finds the production of local food supplements crucial for the local circular economy and their sustainable business. During this project, the consortium partners will investigate sustainable extraction methods of BACs from local waste streams (duurzame chemie: bronnen en grondstoffen). More specifically Zuyd, CHILL and Phytopharma will pursue the “green” extraction of quercetin (BACs) from locally sourced onion waste. The partners will explore various extraction and purification methods needed to evaluate a potentially sustainable business model. Furthermore, the bioavailability of quercetin will be enhanced by encapsulation.
