From agricultural greenhouses to water bottles, together with a recipe for a bread sandwich, the plastic deeply reworked all of the agri-food business. Confronted with a rising drawback of plastic air pollution, we will draw inspiration, thru get entry to to “urban metabolisms”, from what used to be performed at first of the 20 th century.
Huge plastic manufacturing has turn into a marker of the second one part of the 20 th century, which is continuously referred to as “the age of plastic”. Their access within the chains of agro-eating values dates from the Nineteen Thirties. It used to be the results of two dynamics.
The primary is the expansion of the oil and automotive and automobile business: plastic is a co-product of oil taking pictures, Petrochemical firms actively wish to make bigger the plastic marketplace, which is used as their identify.
The second one intensification of agriculture, after the 2d Global Struggle, handle the galoping of demographics.
Sluggish, however the mass use of plastic has modified meals and agricultural practices deeply, and to say meals themselves.
These days, the affects at the surroundings and affects at the surroundings, particularly within the type of micro and nanoparticles, had been confirmed. Control (together with recycling) plastic waste isn’t the one factor in query: it is only the life of the plastic this is involved.
However measures to cut back or prohibitions of plastic fabrics within the agricultural business, from the sector to area client, can’t be implemented with out world enthusiastic about present manufacturing practices, distribution and meals intake.

Packaging meals used to be first and stays the primary use of plastic within the meals business. This corresponds to the ancient second of trade in the best way meals is stored and transported, particularly due to cooling.
It is usually the time of reconfiguration distribution circuits with grocery store building. Plastic then turns into essential and contributes to the structuring of the worldwide meals marketplace as we all know nowadays.
Certainly, the packaging permits for the extension of the meals’s closing date and above all, facilitate the intake of meals and drinks.

Plastic even trade meals. That is the case for a sandwich bread this is offered in plastic baggage. In 1937. Dupont corporate has introduced analysis and building (R & D) a undertaking that resulted in the addition of “Mykoban”, antifungal, to flour, to cut back the danger of molds.
The plastic due to this fact modified the best way we devour or even the character of what we devour. They preferred meals that processed the multitude of intermediaries and contributed to increasing the distance between manufacturers and shoppers packed, frozen or packed meat or fish.
Learn how to get out of “agriplasticy”?
Introductory from supermarkets, agricultural practices became in flip through plastic. The primary presented within the Fifties instead for glass in horticultural greenhouses, changed into standard for the reason that Seventies for gardening available on the market underneath tunnels and hay.
In Europe, the growth of plastic has facilitated a not unusual agricultural coverage (CAP). Introduced in 1962. yr through the Ecu Financial Group (EEC), to start with used to be supposed to inspire extensive and productive agriculture.
On the other hand, plastic tunnels permit fruit or vegetable manufacturing in irrelevant soils, to increase the manufacturing seasons and cut back insecticides. Since then, surfaces coated with plastic greenhouses or tunnels in Spain and France are nonetheless expanding.
However those plasticification of sure cultures additionally track socio-professional adjustments. In large plains coated with plastic tunnels housing (or different) vegetation with top added, hard work is continuously used, which is international, seasonal and inexpensive. Works in tricky prerequisites.

On this approach, the plastic attacked manufacturing practices and meals distribution circles. The phrase “agriplastic” testifies to the intricate, financial and technical components, whose dynamics most often strengthens over the years. Those effects, after a couple of a long time, in what shall we describe as a socio-technical lock.
What are we able to do to become independent from from this dye plastic within the meals business? Since plastic represents the values described, it could be naive that you’ll want to take care of this business group whilst getting rid of plastic fabrics.
This commentary, on the other hand, must now not suppress resolution makers inactiveness. As a substitute, he requires a perfect mirrored image on imaginable reorganization of Agri-Meals chains. With a purpose to get started this mirrored image, we recommend that we go back to a couple historical past categories.
Plastic and discovering waste
Firstly of the 20 th century, the financial system of meals flows between rural and concrete populations used to be operating in virtually closed loops. Fabrics which have been rejected have been used, as an example within the type of fertilizers, through others.
In that context, the very perception of waste nonetheless does now not exist, as a result of not anything used to be rejected or handled as without equal waste (because of this it may now not be additional processed in present techno-economic prerequisites).
Human feces are then noticed as agricultural fertilizers, cloths can turn into paper, and hard work animal corpses are used once more to make glue and different day-to-day merchandise.
The get a divorce of those “urban metabolism”, as described through Sabine Barles, is traditionally becoming the illusion of artificial chemistry. The commercial advanced is then set which produces fertilizers, plant coverage merchandise, 3 classes of goods representing present agricultural chains.
It’s not at all imaginable – neither even fascinating – to identically reproduce city metabolisms of the start of the 20 th century. They relied closely relied at the mobilization of a big overpaid staff dwelling in poverty, equivalent to a material fabric.
However, we will stay the theory of systemic, world and metabolic get entry to as a substitute of merely looking for the substitute of plastic fabrics that may flip very similar to difficulties. Subsequently, the problem of second look, with stakeholders, all sectors of agro-food meals that goal to extend on plastic sobriety.
This newsletter is in keeping with a “plastic used in agriculture and for food” INRAE / CNRS, revealed in Might 2025. years.
