Abstract

The invention relates to methods for converting extruded expanded polystyrene by compacting the material using a heat source, reducing its volume and facilitating transportation, storage and handling. A method of cold conversion of the material obtained by the addition of solvent, producing a basic resin. A method of hot conversion of the material obtained, by the addition of fat and vegetable resin and by melting these products, results in a compound having the same appearance and the same properties as ivory.

Description

PROCED@ DE RECYCLAGE DE DECHETS
DE POLYSTYRSNE EXPANSE
La présente invention concerne une méthode de récupération, de recyclage et de transformation de déchets du polystyrène, expansé, estrudé qui encombrent souvent les entrepôts des grands magasins, des chantiers de construction, et que l'on retrouve parfois jusque sur les plages.WASTE RECYCLING PROCESS
OF EXPANDED POLYSTYRSNE
The present invention relates to a method for recovering, recycling and transforming waste polystyrene, expanded, etched which often clutter the warehouses of department stores, construction sites, and which is sometimes found even on the beaches.

La collecte (dochets volu @neux et encombrants), et la destruction de ces matières non piodégradables (dégagement des Sazs et substances toxiques et polluantes) posent des problèmes aux services d'enlèvement et de destruction des ordures et déchets industriels. The collection (bulky and bulky waste), and the destruction of these non-biodegradable materials (release of Sazs and toxic and polluting substances) pose problems for the services of removal and destruction of industrial refuse and waste.

L'agence atonale de Récupération et d'Elimination des Déchets, a signalé un procécé de recyclage du polystyrène expansé par une méthode de broyage mécanique puis l'incorporation à des terreaux et composts en vue de les alléger. Il n'a pas été signalé å'autres applications connues par cet organisme. The atonal agency of Recovery and Elimination of Waste, announced a process of recycling of the expanded polystyrene by a method of mechanical grinding then the incorporation in compost and compost in order to lighten them. No other applications known to this agency have been reported.

Le procé'é technique employé est le suivant.The technical process used is as follows.

- Première phase : Collecte, tri, lavae, séchage. - First phase: Collection, sorting, washing, drying.

- Deuxième phase : Transformation mécanique et thermique. - Second phase: Mechanical and thermal transformation.

fusion de la matière sous l'action d'une source de chaleur (phénomène de liquéfaction passager puis de compactage : perte importante de volume).melting of the material under the action of a heat source (phenomenon of temporary liquefaction then of compaction: significant loss of volume).

Broyage mécanique de cette matière solide et dense (obtension de granulés de taille diverse en fonction des caractéristiques des opérations de broyage) facilitant le stockage et le transport.Mechanical grinding of this solid and dense material (obtaining granules of various sizes depending on the characteristics of the grinding operations) facilitating storage and transport.

Transformation chimique à froid.Cold chemical transformation.

élange de ces granulés finement broyés mécaniquement, avec un dissolvant puissant (toluène). Celui-ci pouvant être associé å divers autres solvants (distillat de pétrole, essence de thérébentine) ou d'origine végétale (alcool) dans une proportion minimale de 30 G ce quidonne une résine de base. Suivant la densité de cette résine on obtient une gamme de produits, dont la consistance va du liquide à la pâte. Les matières obtenues sont
- Vernis, colles, revètement ~perméables.mixture of these finely mechanically ground granules, with a powerful solvent (toluene). This can be combined with various other solvents (petroleum distillate, essence of therebentine) or of vegetable origin (alcohol) in a minimum proportion of 30 G which gives a basic resin. Depending on the density of this resin, a range of products is obtained, the consistency of which ranges from liquid to paste. The materials obtained are
- Varnishes, glues, coating ~ permeable.

A ces produits peuvent être incorporés des adjuvants liquides et des colorants.Liquid additives and colorants can be incorporated into these products.

A la résine de base on peut ajouter des charges.Fillers can be added to the base resin.

- Sables et granulats pour la fabrication d'enduits et de produits utilisables dans le bâtiment (moquette de pierre). - Sands and aggregates for the manufacture of plasters and products usable in the building (stone carpet).

- Tissus de verres, fibres composites, colorants, sciures de bois, charges granulés plastiques pouvant trouver application dans l'industrie.  - Glass fabrics, composite fibers, dyes, sawdust, plastic granule fillers that can be used in industry.

Transformation à chaud. La matière première finement broyée mécaniquement est mélangée avec des produits gras d'origine animale ou végétale. Les meilleurs résultats obtenus sont avec les huiles de table. La matière grasse utilisée est mélangée à chaud avec 10 ç de résine de pin. Le tout est filtré à chaud à l'état liquide. Le mélange obtenu est additionné à la matière première broyée dans des proportions de l'ordre de 15 et portée à une température de 200 à 2300 C. On se trouve en présence d'un produit liquide nacré, ayant l'aspect d'une huile épaisse, pouvant être coulée aisément dans un moule. Aprés refroidissement ce produit se démoule sans problèmes, et présente l'aspect et les caractéristiques de l'ivoire.  Hot transformation. The finely mechanically ground raw material is mixed with fatty products of animal or vegetable origin. The best results are with table oils. The fat used is mixed hot with 10 ç of pine resin. The whole is filtered hot in the liquid state. The mixture obtained is added to the ground raw material in proportions of the order of 15 and brought to a temperature of 200 to 2300 C. It is in the presence of a pearly liquid product, having the appearance of an oil thick, which can be easily poured into a mold. After cooling, this product can be removed from the mold without problems, and presents the appearance and characteristics of ivory.

Recyclage de déchets actuellement jetés et détruits avec des conséquences néfastes pour l'environnement. Recycling of waste currently discarded and destroyed with harmful consequences for the environment.

Création d'une activité de collecte, transformation par ce procédé, puis élaboration d'une gamme de produits dérivés. Ces produits seraient ensuite diffusés par les canaux habituels en fonction des marchés visés (bricolages, bâtiment, industries chimiques et plastiques ammeublement, scultures).Creation of a collection activity, transformation by this process, then development of a range of derivative products. These products would then be distributed through the usual channels depending on the target markets (DIY, construction, chemical and plastic industries, furniture, sculptures).

Les opérations de prétraitement et éventuellement la transformation chimique préliminaire du polystyrène expansé pourraient être effectuées par des moyens mobiles déplacés sur les lieux même de collecte.  The pretreatment operations and possibly the preliminary chemical transformation of the expanded polystyrene could be carried out by mobile means moved to the same collection site.
