Het Nieuwe Telen (HNT) heeft in haar theoretisch kader de teeltprocessen ingedeeld in zes balansen. De energiebalans, de waterbalans en de assimilatenbalans van de plant en de CO2 balans, de vochtbalans en de energiebalans van de kas. In dit project is onderzocht of de mineralenbalans, de ecologische balans en de hormoonbalans nuttige aanvullingen zijn op de bestaande balansen van HNT. Aanbevelingen: faciliteer onderzoek naar metingen die het mogelijk maken de status van de plant te volgen m.b.t. de mineralenbalans en ecologische balans.
Deze publicatie presenteert de resultaten van het Smartest Connected Cargo Airport Schiphol (SCCAS)-project: een tweejarig onderzoek naar logistieke innovaties die de concurrentiepositie van Schiphol op de luchtvrachtketen versterken. In dit project hebben KLM Cargo, Schiphol Nederland, Cargonaut, TU Delft en Hogeschool van Amsterdam samen met diverse partijen in de luchtvrachtketen nieuwe inzichten ontwikkeld om het afhandelingsproces op Schiphol te stroomlijnen en de productkwaliteit in temperatuurgevoelige ketens zoals bloemen en farma beter te beheersen.In Europa heeft Schiphol een sterke positie: het is de derde vrachtluchthaven na Frankfurt en Parijs. Door de beperking van het aantal beschikbare slots op Schiphol krijgen andere luchthavens zoals Brussel, Luik en Luxemburg de kans om extra lading aan te trekken. Het is daarom de ambitie van Schiphol zich te ontwikkelen tot de Europese voorkeursluchthaven voor logistiek hoogwaardige goederenstromen zoals e-commerce, farmaceutische producten en bloemen, en zich te onderscheiden door een efficiënt en betrouwbaar afhandelingsproces. Om die positie te bereiken zet Schiphol in op vier concrete innovatiedoelstellingen:- verbetering van transparantie in de keten door het delen van informatie;- inzicht in logistieke prestaties op basis van volledige en betrouwbare data over zendingen;- efficiënte en betrouwbare aan- en afvoer van luchtvrachtzendingen (landside pickup & delivery);- procesverbeteringen in de supply chains van temperatuurgevoelige producten.
Cut, cooled, packed, transported and traded all over the world, flowers represent a showcase of a worldwide integrated trade-logistics system. As one of the most perishable, vulnerable and time-critical products, speed is everything in harvesting, moving and trading of flowers. In the international trade of flowers and logistics of florticulture products, the Netherlands is the largest center of trade and logistics of flowers, taking a share of more than 40% in global cut flower export volume. When COVID-19 hit the world, this ever-moving system came to a full stop. What did this mean for the trade and logistics system? Which players were hit most? Did the crises change the system, just interrupt it or has it set the stage for developments already under way to strengthen and accelerate? This chapter presents and discusses the international position of the Dutch trade-logistics system as the most dynamic part of a worldwide flower industry. It sketches key trends in the industry over the last decade and draws a line towards possible post-COVID-19 scenarios for the worldwide flower industry and the international position of the Netherlands. The Dutch flower industry has shown incredible resilience to the external shock of COVID-19, but the crisis also has uncovered some weaknesses of the international flower industry. However, the chapter concludes that it is unlikely that these weaknesses will change the direction of developments in the sector, some of which already started to take shape in the 1970s. The chapter is based on pre-COVID-19 research and literature on the trade-logistics hub of the Netherlands, an analysis of trade and logistics data from around 2000 up to the first months of 2021, and existing economic scenarios for the flower industry and world trade.
Chemical preservation is an important process that prevents foods, personal care products, woods and household products, such as paints and coatings, from undesirable change or decomposition by microbial growth. To date, many different chemical preservatives are commercially available, but they are also associated with health threats and severe negative environmental impact. The demand for novel, safe, and green chemical preservatives is growing, and this process is further accelerated by the European Green Deal. It is expected that by the year of 2050 (or even as soon as 2035), all preservatives that do not meet the ‘safe-by-design’ and ‘biodegradability’ criteria are banned from production and use. To meet these European goals, there is a large need for the development of green, circular, and bio-degradable antimicrobial compounds that can serve as alternatives for the currently available biocidals/ preservatives. Anthocyanins, derived from fruits and flowers, meet these sustainability goals. Furthermore, preliminary research at the Hanze University of Applied Science has confirmed the antimicrobial efficacy of rose and tulip anthocyanin extracts against an array of microbial species. Therefore, these molecules have the potential to serve as novel, sustainable chemical preservatives. In the current project we develop a strategy consisting of fractionation and state-of-the-art characterization methods of individual anthocyanins and subsequent in vitro screening to identify anthocyanin-molecules with potent antimicrobial efficacy for application in paints, coatings and other products. To our knowledge this is the first attempt that combines in-depth chemical characterization of individual anthocyanins in relation to their antimicrobial efficacy. Once developed, this strategy will allow us to single out anthocyanin molecules with antimicrobial properties and give us insight in structure-activity relations of individual anthocyanins. Our approach is the first step towards the development of anthocyanin molecules as novel, circular and biodegradable non-toxic plant-based preservatives.
The Dutch floriculture is globally leading, and its products, knowledge and skills are important export products. New challenges in the European research agenda include sustainable use of raw materials such as fertilizer, water and energy, and limiting the use of pesticides. Greenhouse growers however have little control over crop growth conditions in the greenhouse at individual plant level. The purpose of this project, ‘HiPerGreen’, is to provide greenhouse owners with new methods to monitor the crop growth conditions in their greenhouse at plant level, compare the measured growth conditions and the measured growth with expected conditions and expected growth, to point out areas with deviations, recommend counter-measures and ultimately to increase their crop yield. The main research question is: How can we gather, process and present greenhouse crop growth parameters over large scale greenhouses in an economical way and ultimately improve crop yield? To provide an answer to this question, a team of university researchers and companies will cooperate in this applied research project to cover several different fields of expertise The application target is floriculture: the production of ornamental pot plants and cut flowers. Participating companies are engaged in the cultivation of pot plans, flowers and suppliers of greenhouse technology. Most of the parties fall in the SME (MKB) category, in line with the RAAK MKB objectives.Finally, the Demokwekerij and Hortipoint (the publisher of the international newsletter on floriculture) are closely involved. The project will develop new knowledge for a smart and rugged data infrastructure for growth monitoring and growth modeling in the greenhouse. In total the project will involve approximately 12 (teacher) researchers from the universities and about 60 students, who will work in the form of internships and undergraduate studies of interesting questions directly from the participating companies.
