A Circularity Evaluation of New Feed Categories in The Netherlands—Squaring the Circle: A Review

“…Since 2001, in order to prevent BSE expansion leftovers form cattle have been banned as feed, the EU also restricted the processing of other animal waste streams such as meat, hides, and bones. Nevertheless, some of these streams were allowed as feed for fish and pets [69]. A change has been forced due to, among other factors, the discussions regarding deforestation for soya production and biomass efficiency usage (i.e., circularity).…”

“…The literature claims that biomass from marginal lands (i.e., less or unsuitable land for crop production due to rainfall, swampy conditions, or poor terrain limitations) grazed by ruminants might relieve pressure on arable land and on food-feed competition [73]. In The Netherlands, two thirds of the land area is used for agriculture and horticulture, of which 53% is grassland (mainly used by the dairy sector), and 12% is used to produce feed-crops, mainly maize [69]. As aforementioned, there are other biomass (grains, scraps, etc.)…”

“…and agriculture (by-)products that are being used as feed. However, the great majority of the raw materials for compound feed is being imported or could not be identified as a new feed source [69,94]. This category thus concerns the production of plants in The Netherlands that have not been traditionally used as feed source, or the local production of others that have been and are used for feeding livestock, but that have been traditionally imported.…”

“…Circularity thinking is also expanding the areas in which we search for biomass. Vijn et al [69] estimated that the amount of roadside clippings was around 240,000 to 250,000 tons of DM-i.e., between 800,000 and 1,200,000 tons of fresh biomass. However, residual flows of roadside management could be polluted.…”

“…Daarnaast blijkt dat alle nutriënten die Nederlanders via voedsel consumeren, niet meer terugkeren in de landbouw-voedselkringloop.Nederland, en Brabant in het bijzonder, zijn een goed voorbeeld van een maximale benutting van alle rest-en bijproducten die in de verwerking van plantaardige en dierlijke producten ontstaan. Keer op keer blijkt dat hier eigenlijk niets meer valt te verbeteren(Vijn et al, 2019). Er zijn slechts enkele lastige reststromen, zoals slachtafval en swill, die om voedselveiligheids-en diergezondsheidsredenen niet gebruikt mogen worden als veevoergrondstof.De verspilling bij de consument is een grote uitdaging.…”
