Certificat environnemental

Votre contribution à la protection du climat !

Lorsque vous utilisez des plastiques recyclés à la place de résines vierge, vous réduisez l’émission des gaz à effet de serre nocifs pour le climat. Et dans des quantités non négligeables. L'université de Magdeburg-Stendal contrôle régulièrement ces faits : ainsi, en 2013, les 27 000 tonnes de granulés recyclés ayant été livrés par notre entreprise ont permis d'éviter presque 60 000 tonnes d'émissions de CO2, qui auraient été produites par la fabrication de produits neufs. Cette quantité correspond aux émissions d'un véhicule de catégorie moyenne qui ferait le tour de la Terre à 8000 reprises.

Depuis 2014, mtm établit un certificat à l'attention de ses clients attestant des réductions d'émission de CO2 réalisées en fonction de la quantité de granulés recyclés achetés auprès de mtm. Ainsi, vous disposez d'une preuve tangible de la politique respectueuse de l'environnement de votre entreprise.

Matière première

Matière utilisée pour notre « upcycling » (valorisation par le recyclage)

À l'heure actuelle, la société mtm est en mesure de traiter jusqu'à 75 000 tonnes de produits entrants par an. Ces matières premières proviennent de différentes sources. Concernant l'approvisionnement en matières premières, nous nous concentrons sur les déchets plastiques composés principalement de plastiques purs et de qualité supérieure. Il s'agit d'emballages en polyéthylène et polypropylène usagés, avec une courte durée de vie, ainsi que de plastiques issus de centres de collecte de déchets encombrants et industriels. Après notre transformation pour en faire des granulés recyclés, nos clients profitent finalement de produits durables et de qualité supérieure. C'est ce que nous appelons l'« upcycling », c'est-à-dire la revalorisation par le recyclage.

Fabrication

Une procédure respectueuse de l'environnement : à partir de produits usagés, nous fabriquons une nouvelle matière première qui protège le climat en économisant autant d'énergie que possible.

Nos procédures sont malheureusement relativement énergivores. C'est la raison pour laquelle nous apportons une attention toute particulière à utiliser tous les potentiels d'économie identifiés. Un système de gestion de l'énergie moderne, certifié selon la norme ISO 50001:2018 y veille. Notre processus de production est certifié selon la norme DIN EN ISO 9001:2015. En outre, nous avons également rejoint la norme de certification européenne EuCertPlast. Toutes les exigences posées par les directives REACh et CLP sont également satisfaites et surveillées à intervalles réguliers.

Lorsqu'ils arrivent chez nous, les déchets plastiques (généralement sous forme de balles) sont d'abord déchiquetés dans de grands broyeurs. Puis, nous retirons les impuretés éventuellement présentes dans les marchandises fournies sous forme de balles par voie sèche et mécanique (métaux, bois, verre, erreurs de tri, sable, cailloux ou papier). Après un premier tri et une nouvelle étape de déchiquetage, les plastiques sont triés par variété et lavés. Nous nous concentrons sur les polyoléfines que sont le polyéthylène et le polypropylène. Nous les séparons et les trions par couleur. Dans l'installation de lavage/séparation combinée, nous séparons également tous les plastiques indésirables, tels que le PET, le polystyrène et le PVC, de même que les résidus. Les matières broyées lavées sont ensuite séchées, avant d'être transformées en granulés recyclés. Lors de cette étape de transformation, la matière est compactée, fondue entre 180 à 240 degrés, mélangée avec les additifs nécessaires, pétrie (plastifiée), filtrée à 180 μm, dégazée à vide, entièrement mélangée (homogénéisée) et finalement formée en grains cylindriques caractéristiques sous l'eau. Ce composé/granulé recyclé est ensuite séché et homogénéisé une nouvelle fois dans des silos de malaxage, avant d'être emballé.

Les compounds recyclés produits de cette manière présentent une qualité supérieure et constituent une matière première idéale pour transformation.

Design for Recyclability

10 Codes of Conduct for Design for Recyclability (DFR)

Together with Borealis and in coordination with many other industry representatives, mtm has developed ten handy codes of conduct for recycling-friendly design. They are addressed to all packaging experts who are interested in the connection between their design decisions and plastics recycling. Following the "Ten Common Rules", you will find an FAQ catalogue that goes into more detail on a number of points. If you have any questions or comments, please feel free to contact us. We look forward to every exchange on this important topic.

 

10 Codes of Conduct for Design for Recyclability (DfR)

At Borealis, we work closely with our value chain partners to develop polyolefin-based material solutions and concepts that accelerate the transition to the Circular Economy. There are promising opportunities for business growth in replacing the linear model of “take-make-dispose” with a more circular one focused on recycling. Polyolefins are an ideal material for designing packaging that can be recycled and these Design for Recyclability (DfR) codes need to be adopted to optimise their recyclability.

DfR incorporates recycling codes of conduct into the design process keeping in mind the end-of-life aspects after its original intended use. These DfR codes are an essential tool for delivering to market plastic packaging, with the right functionalities, yet also, helps conserve natural resources and minimise waste (including product waste) disposal or incineration and littering. DfR can maximise recycling rates for all kinds of plastic packaging because it makes separation and reprocessing more efficient. It also ensures the steady and affordable supply of high-quality recyclates, from so called “recycling-ready” packaging. Those recyclates also have a significantly lower CO2 footprint and require less fossil fuel in the manufacturing process versus production of virgin resin.

While there are many aspects of plastic packaging design that make packaging “recycling-ready”, we have identified three key overarching codes of conduct when designing the function of the packaging eg, preservation, safety, wastage

  • Use as few different polymer types, components and materials as possible in the design of the overall packaging. This applies to all packaging components such as the body, closures (caps, liners seals), lidding and any other additional components.
  • Make it easy to strip and wash off all decoration (e.g., labels or sleeves and adhesive, printing, ink etc) from the main functional part of the packaging
  • By no means, should packaging, designed according to the DfR codes, come at the detriment of food/product preservation/protection

The following “dos and don’ts” help our partners and customers navigate the relatively new and complex field of DfR in polyolefins. These codes are based on current circumstances and technologies used in European countries and we recommend that you regularly consult trade and industry bodies such as Plastics Recyclers Europe (PRE) and the Institute Cyclos-HTP in order to stay up to date on emerging technologies, waste stream evolutions, and new sorting and reprocessing capabilities

Questions and answers about Design for Recyclability

Here you will find answers from experts to general and specialist questions on the subject of the recyclability of plastic packaging:

 

1. General Questions

 

1.1 How can we improve economics of the whole system?

In Europe there is a trend to broaden the collection from cherry-picking (valuable PET- beverage bottles and PE-HD-bottles only) to other streams of low to no-value materials (PTT and film/flexibles). This will result in higher costs in the fist step. From a societal view these costs partly are occurring anyhow, because the streams will otherwise have to be treated and paid for as waste by municipalities. With these materials entering the EPR-scheme area of responsibility, the following standardization steps on all levels and for all players in the value chain become even more important:

  • Use of a few main polymers: PE, PP and PET (but only for beverage bottles), avoid low-market volume materials which are difficult to sort out and end up as bad yield 

  • Collect all plastic (packaging) separately 

  • Standardize sorting to create reliable, quality managed and larger input waste 
streams for recycling (do not re-invent the wheel in every country) 

  • Build larger recycling factories, like competing materials paper, metals, glass have 
already, using economies of scale 

  • Integrate recyclates into primary polymer production 
and compounding 

  • Reduce bad yield in sorting and recycling (see also 
5.1. below): 


    • Avoid paper/plastic combinations (composites, labels,...)

    • Reduce usage of pigments and inks (temperature unstable above 180 degrees)

    • design packaging in a way that marketing messages and main body of the pack can be separated in a mechanical recycling process (water soluble inks, density difference between sleeves/labels and main body)

    • Use markers to make fully body sleeve send sorting message for the specific polymer used in main packaging body
    • Design packaging that is easy to empty

    • Avoid density-modifying additives in plastic packaging

1.2 When will there be recycling solutions for PET blister packages?

Sorting and recycling of PET pots, tubs, trays and blisters currently still encounters difficulties e.g. identification of multilayer material, viscosity, contamination with labels, pigments, prints and filled goods. Clean monolayer PET–PTT and blisters could be added to a PET bottle recycling stream, but only to a lesser extent. It seems more fruitful to single out these packaging (at additional cost) once sustainable options are found. This is currently not the case with no light at the end of the tunnel. The problem would be solved if the above recommendation to concentrate on perfectly easy to recycle polymers PE and PP would be heeded for non-beverage bottles.

1.3 How can we introduce another driver than “light-weight” in sustainable policies?

Like safety, circularity needs to come first! Packaging design decisions are often backed up by Life Cycle Analyses (LCA). Given the current set-up of LCA, light-weight packaging and food waste reduction is favored over recycling issues, and LCAs do not take into account consumer behavior and littering. Either this changes or circularity has to become a separate, essential requirement on top.

  • I believe that LCA should not be used to favor unrecyclable options over recyclable options. 

  • How can a valuable packaging be designed and still be recyclable? This paradigm shift can be introduced by industry itself, but might be set by the legislator (e.g. by changing the Eco Design directive). 

  • Changing the thinking in companies towards more circularity is a matter that has to be implemented top-down, e.g. by changing incentives for packaging procurement. 

  • Check how and which packaging is over-designed and over-functional at the cost of its circularity. Creativity of packaging designers has to be unleashed to find new and circular designs, which only give the functionality that is actually needed. 

  • Use circularity as a positive marketing message but beware of green-washing.


1.4 Are we all informed of all the full chain critical points? 


No, packaging chains are highly complex. Due to the sequential steps in creating a packaging, filling it, using it, etc., communication is also mostly sequential, i.e. between raw material supplier and packaging producer, between packaging producer and filler, collectors, sorters and recyclers. We need a more holistic communication approach in order to create a better understanding of sustainable solutions and their implementation. Platforms for this dialogue are e.g. PCEP (Polyolefins in a circular economy platform), CEFLEX, The Round Table for Eco-design of IK (Industrievereinigung 
Kunststoffverpackungen), but also NPEC (New Plastics Economy by Ellen McArthur Foundation).

1.5 Do you think that plastics recycling is possible all around the world?

Formal and informal structures already carry out plastic recycling all around the world. Of course, the level of technology and automation used is very different. However, even under very modest conditions people with entrepreneurial and engineering spirit do recycling of plastics. To get a better idea of it check out this video: www.youtube.com/watch or www.youtube.com/watch. The challenge is to expand these approaches to plastic packaging and items that, because of their design, do not easily find their markets after use: They are “not worth” collecting, sorting and recycling. Unfortunately, by volume, that is the vast majority of packaging. Even in developed countries in Europe there still is reluctance to expand collection and sorting to these (in many cases flexible and PTT) packaging streams.

 

2. Brand-Owners

 

2.1 How to engage more brand owners and retailers?

We would recommend inviting the brand owners and retailers to participate in circular economy platforms like PECEP and CEFLEX. It is here where decision criteria up and down the value chain are being discussed, knowledge is transferred and common ground is looked for. Implementing those learnings in participating companies will create a pull effect because they will act as role models for circular behavior and – via competition – make others follow.

2.2 What information is needed to help redesign packaging to improve recyclability?

Recyclability is just one piece of the cake. To understand how to redesign packaging in order to attain the highest degree of circularity possible it is crucial to know the general technical conditions of collecting, sorting and recycling. A, in theory on a lab scale, fully recyclable packaging is nice but we must also make sure that the sorting plants are able to identify this type of packaging and sort it into the right waste stream (fraction). If packaging designers operate within this framework, we would automatically increase the recyclable share and reduce bad yield in our waste streams. Information about Recyclability is provided by Recoup in their paper on “Recyclability by Design” (downloadable under http://www.recoup.org/downloads/info- required?id=478&referrer=http%3A%2F%2Fwww.recoup.org%2Fp%2F275%2Fpublications) or by the design tool “Recyclass” provided by PRE (Plastics Recyclers Europe – www.recyclass.eu)

 

3. Design

 

3.1 Design for Recyclability (DFR) is moving the responsibility to the designer / Brand-Owner. How can the raw material supplier be of help?

Raw material suppliers are also active in packaging material design and compounding. Their overwhelming knowledge of polymer technology and their R&D capacities can be useful when it comes to developing new, more circular materials. Blending virgin and recyclates on the producer level is an option, developing physical/chemical large scale processes may probably only be done by large petro-chemical companies.

3.2 What must product managers know to enable better recyclability?

Please check answers number 1.1, 1.3., 2.2

 

4. Collection


 

4. What is the biggest problem in collecting?

There are three major issues, which need improvement:

4.1  Availability of collection infrastructure: At a European scale, a lot of member states do not have their population fully covered in terms of collection infrastructure for PTT and flexible packaging. A lot of member states initially focused on bottle collection, regarding PTT and film collection as too costly. More and more collection schemes integrate PTT and flexibles, but there is still a long way to go. 


4.2  In 2017 it should have become common knowledge that plastics must be collected separately from (wet and dry) normal household waste. There are technical, legal and hygiene issues with the so called comingled collection which at the end of the day all reduce the willingness of the converting industry to use recyclates coming from that type of collection. Paper and glass are collected separately in the vast majority of regions, plastics deserve the same care. 


4.3  Education of citizens: Unfortunately, the quality of collected light-weight packaging is often low. The number of unwanted objects is high, packaging is often not (fully) emptied, and different packaging types are either not separated or stacked into each other. PRE-Schemes should educate their citizens in order to create a better input quality for sorting centers, which should then translate into better qualities for 
recyclers. Municipalities also need to focus more on educating instead of seeing collection and sorting as a business opportunity only and leaving the rest to the industry.

 

5. Recycling Technology


 

5.1 What are recyclers’ biggest problems today?

  • See 1.1.

5.2 Sleeves materials to be chosen for HDPE, PP, PS, else?

As long as sleeves cannot convey a sorting message related to the packaging’s main body material:

Given the availability of markers needed to communicate via a PET-sleeve that the packaging’s main body is e.g. PP, there should be a significant density difference between sleeve and main body. 


5.3 Level of residue? Complete emptying?

It is obvious that residue will not be recycled at the recycler’s and hence reduces production yield. With packaging getting thinner and thinner, yield drops even further. It is therefore highly recommended to design easy to empty packaging, also to prevent general waste of packed products. How can you justify the following packaging for liverpaté:

  • super efficient, down gauged film 

  • highly functional PET/PE/..../barrier 

  • paper-label for marketing information, PET-Layer for gloss 

  • extended shelf-live


if it is so flexible that it cannot be emptied and not be conveniently handled any more by the consumer? Prevention of food waste is not only measured in shelf life. 


5.4 What is the critical point or points in recycling PTTs?

Compared to other packaging types (like films or PP/PE-bottles) PTT (incl. smaller flexibles) are much more versatile when it comes to their design. In that fraction, all circular design flaws are concentrated. Please read 1.1.

5.5 What shall be the message on Black containers?

Optical sorting devices work with near infrared light being reflected into a camera lens and analyzed. Black and very dark colored items absorb that light instead of reflecting it. Hence, the container will not be detected as to polymer type and end up in bad yield or in a black fraction that consist of all black items be they PE, PP or PET. The resulting recyclates will be bad in yield, quality and achievable price.

There might be solutions in the future (better optical sorting, tracer-based sorting, etc.). However, these will still create a black stream suitable only for black recyclate applications. Therefore, today and in the future, black containers should be avoided.

5.6 What is better: rPET Trays or PP Trays?

Today, PET bottle recyclates find one of their larger markets in PET-Thermoforms (PTT made of rPET). Unfortunately, these containers are not being recycled (see above 1.2.) whilst, at the same time, they replace perfectly easy to recycle PP and PE-PTT.

We would therefore recommend the use of PP trays rather than rPET trays.

In France Valorplast is trying to force PET-Bottle-recyclers to accept trays in their streams. It remains to be seen how this works out.

5.7 Is separation by density (water bath) still needed in the future?

Density separation helps separating unwanted material from wanted material. In addition, the water has a cleaning effect on the flaked material. Even with optical sorting improving at high speed, we believe that the identification of multilayer packaging, sleeved packaging, additive-filled packaging, or other packaging combinations (e.g. plastics/paper), without density separation will not work efficiently.

5.8 Are multilayers a NO GO for recycling?

Multilayers are a no go for recycling if layers are of different polymer types and compounded physically or not mechanically separable. Even if a certain degree of compatibility is given, the glues used will have a negative effect as well. Different polymer types will contaminate recyclates and reduce quality if not separable in the recycling process. Certain barrier-layers can be accepted. Please see “Recyclass” for further details.

5.9 What is the problem with opaque PET? What is the solution?

Opaque PET is, because of its color additives, a contaminant of other streams and the most unwanted material in PET recycling. If opaque PET was separated into a single stream, recycling options would still be scarce. Separating opaque into a single stream adds additional costs to the system at currently little gain in recycling options. Today, opaque PET mostly ends as sorting waste and is incinerated.

If opaque PET spreads further into the market, it should be singled out and recycling should be found, all this at additional costs.

5.10 In which application are the PTTs recyclers no way?

The legislator has created high barriers for certain product applications:

  • Packaging with food contact
-
  • Children’s toys

  • Medical appliances

OEMs have additional requirements as to odour and colour. There are still a lot of challenges to be tackled which will take more R&D than in the past.

5.11 Ability to recycle PE and PP together? Markets?

PE and PP can be and are currently recycled into recyclates replacing virgin material. Typical end markets are transport & logistics (pallets, crates etc.), construction (buckets, tools, spacers etc.), household & garden (buckets, composters etc.) and various other technical applications.

5.12 How can we keep functionality using monoresins instead of multilayers?

Packaging designers have been very creative designing today’s packaging. We do not believe that packaging will become simple again, but more design efforts have to focus on the circularity of packaging. We support and contribute to a more intense communication between packaging designers, brand owners, and recyclers.
