RECYCLABLE GREENHOUSE INSULATION ASSEMBLY
Description
The present invention relates to a greenhouse insulation assembly comprising multiple insulation screens of recyclable polymer and attachment means. The present invention further relates to methods for providing a greenhouse with a recyclable insulation screen assembly and use the recyclable insulation screen assembly for providing a greenhouse with insulation.
To improve the energy management and a more efficient climate control of a greenhouse, special energy screens or insulation panels are being used in order to reduce the energy needed to maintain the optimal climate and temperature in the greenhouse. These energy or insulation screens are stretched along the side walls and just below the roof construction and serve to prevent energy losses to the outside of the greenhouse. At present most of these insulation screens or panels for a greenhouse are comprised of polymer, such as polycarbonate, polyethylene, and polyurethane and may be a single twin or triple walled panel in view of degree of insulation, superior strength and excellent heat retention, durability, and light diffusion/transmission. One of the efficient, simplest and cheapest ways to insulate a greenhouse is to use polyethylene (PE) plastic foil.
Insulation screens such as PE foils are installed in a greenhouse by attachment of the screens to each other and to the inside of a greenhouse's frame using metal clips, drawing pins or a staple gun. However, once attached to each other, removal of the insulation screens (or forming an insulation deck) is time consuming and tedious effort, for example in the event that light, temperature or other climate conditions need to be adjusted inside the greenhouse. Furthermore, the insulation screens are removed as a whole including the attachment means such as the staples or clips that bind together the insulations screens. making the removed insulation screen unsuitable for recycling as a whole.
In order to reduce the carbon footprint of greenhouses, the insulations screens are being recycled. In the recycling process. the insulation screens are being shredded into small pieces, however the staples and clips that are also included herein lead to damage and clogging up of the extruders and filters being used in the recycling process. In order to recycle these insulation screens, first the attachment means including metal staples or clips, need to be separated from the
PE foils. This is a time consuming and costly process, making the recycling of such insulation screens less favourable.
Considering the above, there is a need in the art for an insulation screen assembly for a greenhouse that provides efficient, cost effective and simple solution to insulate a greenhouse while at the same time is fully recyclable when removed from a greenhouse as a whole. The insulation screen assembly should be recyclable without the need for further steps to prepare the material for recycling. In addition there is a need in the art for a method for the installation of such ingulation screen assemblies in a greenhouse.
It is an object of the present invention, amongst other objects, to address the above need in the art. The object of present invention, amongst other objects, is met by the present invention as outlined in the appended clauses.
Specifically, the above object, amongst other objects, is met, according to a first aspect, by the present invention by a greenhouse insulation assembly, wherein the assembly comprises multiple insulation screens comprised of polyethylene (PE) polymer, and one or more attachment means, preferably a polymer strip, comprised of a PE polymer for attachment of the multiple
IO insulation screens to each other, wherein each of the insulation screens comprise multiple apertures in its outline (or circumference) arranged for receiving said attachment means, and wherein the attachment means has a yield point of between 5 to 40 N/mm2, preferably 10 to 30 N/mm2, more preferably 15 to 25 N/mm?2, as measured by ISO1 184. The insulation screens are attached to one another by the attachment means, preferably PE strips, via the apertures in the circumference of said screen. The assembly comprises both screen and attachment means which are consisting of a thermoplastic PE polymer that is fully recyclable by heating up the assembly material as a whole, without the need for pre-processing steps to make the material suitable for recycling. This in contrast to the know insulations assemblies comprising either non fully recyclable materials including metals, staples and pins that need to be removed first before recycling of the screens.
Lower yield points result in less flexible and brittle material, unsuitable for the present purpose of providing a insulation screen in a greenhouse. The yield point is the point on a stress-strain curve that indicates the limit of elastic behaviour and the beginning of plastic behaviour. The polymer insulation screen and attachment means should have a yield point of at least 5 N/mm2. such that it will deform elastically at the exerted pressures in a greenhouse (wind, movement, during installation) and will return to its original shape when the applied stress is removed. Once the vield point is too low (i.e. below 5 N/mm?2), some fraction of the deformation of the insulation panel and attachment means are permanent and non-reversible leading to deformation and resulting in decreasing insulation properties and durability of the assembly in the greenhouse.
The yield point must be at least 5N/mm2 to ensure elasticity of the attachment means, preventing or reducing the risk of breaking of the assembly when attached to each other to form a whole insulation deck in a greenhouse. The vield point value is related to a thickness of the polymer material and is determined according to ISO1184. For example, 10 N/mm2 is measured on a 15mm strip of 0. Imm thick; 15 mm x 0.1 mm = 1.5 mm?2, resulting in an absolute force of
I5N. At the same thickness, but having a strip of 30 mm, results in a surface of 3mm2. In order to withstand the same force of 15N, the yield strength of the attachment means of PE material should therefore be 5 N/mm2.
According to a preferred embodiment, the present invention relates to the greenhouse ingulation assembly, wherein the assembly consists of one or more PE polymer selected from the group consisting of linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), very -low-density polyethylene (VLDPE), high-density polyethylene (HDPE), ultra-high- molecular-weight polyethylene (UHMWPE), ulta-low-molecular-weight polyethylene (ULMWPE), high-molecular-weight polyethylene (HMWPE). high-density cross-linked polyethylene (HDXLPE), cross-linked polyethylene (XLPE), medium-density polyethylene {MDPE), chlorinated polyethylene (CPE), and ethylene acid copolymers. preferably LLDPE and/or LDPE.
According to another preferred embodiment, the present invention relates to the greenhouse insulation assembly, wherein the insulation screen is of 100% PE
According to another preferred embodiment, the present invention relates to the greenhouse insulation assembly, wherein the attachment means is of 190% PE
According to vet another preferred embodiment, the present invention relates to the greenhouse insulation assembly, wherein the multiple insulation screens and the attachment means are of identical identical PE composition.
According to a preferred embodiment. the present invention relates to the greenhouse insulation assembly, wherein the assembly 1s free from metal or wood. The greenhouse insulation assembly is for 100% recvclable in a single recycling step, without the need for further pre- treatment steps to improve or clean up the material before being recycled. There are no metals or wood materials in the assembly of the invention present that need to be removed, as compared to the known greenhouse assembly systems. The greenhouse insulation assembly provides a efficient, cost effective and simple solution to insulate a greenhouse. The assembly can be removed from a greenhouse as a whole and subsequently recyclable without the need for further steps to prepare the material for recycling.
According to yet another preferred embodiment, the present invention relates to the greenhouse insulation assembly, wherein the multiple apertures of the insultation screen are located opposite each other on the longitudinal sides of the insulation screen..
According to another preferred embodiment, the present invention relates to the greenhouse insulation assembly, wherein the attachment means has a thickness of at most 0.5 mm, preferably at most 0.25 mm, more preferably at most 0.1 mm. The thickness of the attachment means is important for handling. Too thin will result in a very elastic attachment means and will result in stretching the film, too thick will result in a very rigid material that is more difficult to handle. The attachement means need to be suitable for weaving through the apertures of the insulation screen and to form a knot. Therefore, too thick attachment means, i.e. a EP strip, of more than 0.5mm becomes too difficult to be knotted.
According to a preferred embodiment, the present invention relates to the greenhouse insulation assembly, wherein the attachment means has a length of at least attachment means has a length of at least 5 cm, preferably at least 50 cm, more preferably at least 500 cm. Short pieces of attachment means, for example PE strips of 5 cm can be used individually between insulation screens to be attached to each other, per set of apertures of both insulation screens. Furthermore, longer PE strips, for example >5 m, can be used as a long tread that can be used to weave the multiple insulation screens together as a whole via the apertures of said screens. When weaving of said attachment means trough the apertures of the insulation screens, the corresponding apertures of the insultation screens apertures are substantially vertically in line with each other, resulting in that the outlines of the insultation screen overlap with each other.
According to another preferred embodiment, the present invention relates to the greenhouse insulation assembly, wherein the apertures have a diameter of between 5 to 50 mm, preferably 10 to 40 mm, more preferably 15 to 30 mm. Apertures should not extend the 50 mm, since the insulation function of the screen will be affected due to the size of the apertures. Too small of aperture, i.e. below 5 mm result in a decreased handling and connectivity of the screens using the attachment means of the assembly of present invention.
According to vet another preferred embodiment, the present invention relates to the greenhouse insulation assembly, wherein the apertures are at least 1 to 100 cm from each other, preferably 5 to 75 cm, more preferably 10 to 60 cm, even more preferably 15 to 50 cm, most preferably 25 to 35 cm.
According to a preferred embodiment, the present invention relates to the greenhouse insulation assembly, wherein the width of the attachment means is at most corresponding to the diameter of the apertures, preferably the width of the attachment means is between 5 to 50 mm, preferably 10 to 40 mm, more preferably 15 to 30 mm.
The present invention, according to a second aspect, relates to a method for providing a greenhouse with a recyclable insulation screen assembly as defined above, comprising the steps of; a) positioning of multiple insulation screens adjacent to each other such that the apertures in the outline of the insulation screen are substantially in line with the corresponding apertures of the adjacent insulation screen, b) connecting the positioned insulation screens to each other using the attachment means and the apertures in the outline of the insulation screen arranged for receiving said attachment means forming a strip of connected insulation screens, c) Optionally, repeating steps a and b providing multiple strips of connected insulation screens in a greenhouse.
The apertures in the circumference of the insulation screen are substantially in horizontally and/or vertically line with the corresponding apertures of the adjacent insulation screen such to be connected with each other to form whole deck or strip of insulation screens,
According to a preferred embodiment, the present invention relates to the method for 5 providing a greenhouse with a recyclable insulation screen assembly, wherein connecting the positioned insulation screens is achieved by weaving of the attachment means through the apertures thereby connecting the multiple insulation screens to each other.
According to another preferred embodiment, the present invention relates to the method for providing a greenhouse with a recyclable insulation screen assembly, wherein the method further comprises the step of positioning of the multiple strips connected insulation screens (comprising multiple insulation screens in connection with each other) and connecting said multiple strips to each other to provide an insulation cover inside the greenhouse comprised of multiple strips of connected insulation screens.
According to vet another preferred embodiment, the present invention relates to the method for providing a greenhouse with a recyclable insulation screen assembly wherein the multiple strips are positioned adjacent to each other such that the apertures in the outline of the insulation screen of the strip are substantially in line (horizontal and/or vertical) with the corresponding apertures of the adjacent strip, and subsequently connecting the positioned strips to each other using the attachment materials and the apertures in the outline of the strips arranged for receiving said attachment means forming an insulation cover.
According to a further aspect, the present invention relates to the use of the recyclable greenhouse insulation screen as described above for providing a greenhouse with insulation.
The present invention will be further detailed in the following examples and figures wherein:
Figure 1: Shows an insulation screen (1) comprising multiple apertures (2) in the outline of the screen. The multiple apertures of the insultation screen are located opposite each other on the longitudinal sides of the insulation screen.

The insultation screens (1, 17) may be connected to each other via knotting of the attachment means (6) using the corresponding apertures of the insultation screens. The insultation screens are positioned adjacent to each other such that the apertures in the outline of the insulation screen are substantially horizontal in line with the corresponding apertures of the adjacent insulation screen. Then the insulation screens are connected to each other using the attachment means and the apertures in the outline of the insulation screen arranged for receiving said attachment means. In case multiple screens, for example 6 screens are attached to each other they form a strip of connected insulation screens that can be arranged as such in a greenhouse providing optimal insulation over the entire length of a greenhouse.

Example
Example | — Installation, removal and recycling of greenhouse insulation assemblies
Greenhouse insulation assemblies have been tested for their easy of installation in a greenhouse, ease of removal from the greenhouse and subsequent recycling of the insulation assembly after use and removal from the greenhouse.
Multiple 100% PE insulation screens are installed in a greenhouse via A) staples or B) via the attachment means, being a strip of 100% PE. and using the apertures in the insulation screen according to present invention. When using staples (A), installation of the screens took about 0,22 minutes per m2 of greenhouse. In case of using the attachment means by providing a knot per aperture, installation of the screens took about 0.28 minutes per m2 of greenhouse. In case of using the PE strip and weaving the insulation screens to each other, installation of the screens took about 0,21 minutes per m2 of greenhouse. Therefore, installation of system A or B is comparable in time, were weaving seem to be the most preferred option. However, removal over the woven PE strips is very easy and will safe a lot of time in case the insulation screens need to be replaced/removed in comparison to staples screens.
When recycling system A, the staples resulted in problems during the recycling procedure.
The majority of the staples that have been used to attach the insulation screen to each other do not sink during washing since they are still attached to the insulation screen. The staples are floating in the washing assembly (used for recycling) and are subsequently fed into the extruder, resulting in damage to the machinery, a slow filtering process and impurity of the recycled polymer as end product. The loss of speed during the recycling process, impurities of the polvmer and damage to the recycling machinery do not occur with recycling of the insulation assembly of the present invention. The assembly was washed and filtered very fast by the screen pack and the recycling extruder without any impurities.
