Biobased PEF (polyethyleenfuranoaat), de nieuwe grondstof voor flessen met koolzuurhoudende dranken (voor Coca Cola en Danone) is niet allen groen, maar ook goedkoper te maken dan zowel fossiel als drop-in groen PET (polyethyleentereftalaat). Het heeft ook nog betere eigenschappen.<\/strong><\/p>\n

\"PEF\"<\/a>Tom van Aken, CEO van Avantium, wordt niet moe het nogmaals uit te leggen. De barri\u00e8rewerking voor zuurstof van PEF is zesmaal beter dan die van PET, en die voor kooldioxide drie maal. Overal scoort PEF beter, niet allen tegen PET, maar ook tegen alle andere mogelijke concurrerende materialen. Bovendien is het ook nog op dezelfde manier en in dezelfde machines te verwerken als PET, de flessenblazers hoeven dus geen nieuwe apparatuur aan te schaffen. Het is zelfs gemakkelijker te verwerken door de lagere smelttemperatuur, en beter in gebruik door de hogere glastemperatuur<\/a>. En last but not least is het – bij grote hoeveelheden – ook nog goedkoper, zeker als je het gaat vergelijken met bioPET, de route die Pepsi Cola wil opgaan. Tom van Aken: Je hebt voor bioPET twee maal zoveel grondstof nodig als voor PEF, dus alleen al vanuit dat gezichtspunt is bioPET een onhaalbare zaak. En vergeleken met fossiel PET gaan de superieure eigenschappen van PEF vast en zeker de doorslag geven.<\/p>\n

Groot aantal fabrieken nodig
\n<\/strong>Tom is vol vertrouwen en lijkt daarin geen ongelijk te hebben. Ze weten, zo zegt hij, al lang dat furanen de enige hernieuwbare biomoleculen zijn met een ringstructuur, en dat dit de weg is naar grote hoeveelheden groene polyesters, polyamiden en polyurethanen. \u2018Wij doen dat via chemische katalyse, nu in onze proeffabriek in Geleen, Limburg die 40 ton per jaar maakt, en binnenkort in een kleine commerci\u00eble fabriek – hopelijk in Nederland of elders in Europa – van 30 tot 50 kiloton per jaar. Over vijf jaar moet er dan de eerste full commercial plant staan die tien maal zo groot is. Die gaat in licentie en dat is wel logisch want alleen al Coca Cola heeft een groot aantal van die fabrieken wereldwijd nodig om PEF flesjes voor haar producten te maken. Om nog maar te zwijgen over de vezel- en de foliemarkt die ook in miljoenen tonnen worden gemeten.\u2019<\/p>\n

Tenslotte kaatst Tom de vraag terug waar al die suiker dan vandaan moet komen voor de productie van PEF: de suiker in de grondstof die zij nodig hebben, is maar een vijfde van de suiker die in de fles zit.<\/p>\n
