Application of a high purity formation process to manufacture AGM battery separators (Absorbed Glass Mat) with microglass fibers, fit for high basis weight (up to 350 gsm) and without chemical binders

Innovative features:
Process optimization has allowed to obtain lower density products, compared to average of market AGM media, as well as a wider range of raw material choice. This enables taylor made developments, for example using functionalized fibers (e.g. nanoalumina) or higher percentage of microglass fibers produced with rotary process with better energy efficiency. Key innovation factors have been the improved product formation and the use of a multi-stage cleaning system applied to microglass fibers impurities

Io Scarico is a web and app platform (ios and android) that simplifies the management of goods unloading. The platform provides an innovative communication tool between the actors of the logistics process: paper mill, suppliers, freight forwarders. Through the dedicated sections of the platform to the single actors, the user has the possibility to plan more efficiently the management of the unloading goods.

Innovative features:
The "Io Scarico" Platform was developed to meet the need to make logistics organization more efficient and faster and to improve the interaction between paper mill, suppliers and freight forwarders. Platform management is possible both via web and app (ios and android) "Io Scarico" is developed with sections dedicated to each actor involved in the logistics process with different functions and clear and intuitive screens. For example, in a "typical" logistic process: Paper Warehouse - sets the number of unloading slot that can be managed in a day for a given product Suppliers - indicate the number of loads to be withdrawn by product type Transporters - require the booking of the unloading Paper mill warehouse - sets the acceptance of automatic or manual bookings and organizes the day of discharges in the best possible way The Platform takes into account and is able to manage the many variables of the logistic process: delays, anticipations, urgency.Furthermore, the Platform can be used as a tool to support logistics in the Comieco case, also in the monitoring of timely withdrawals and the correct provision of material.

Fibre recovery from pulper waste for the production of recycled cartonboard

The disposal of production waste of a paper mill generates significant environmental and economic inefficiencies through their transfer to landfills and incinerators. The sustainability strategy of RDM Group sets among its foundations the reduction of environmental impacts. This concept, which goes well with production efficiency and cost optimization, means for the Group the minimization of waste and, at the same time, the maximization of the incoming raw materials’ use. And it could not be otherwise, considering the importance and size of RDM Group, which is the second European producer of recycled coated cartonboard, and the first manufacturer in Italy, in France and in the Iberian Peninsula. The process of converting urban paper waste into recycled cartonboard requires intense purification activities aimed at eliminating all non-fibrous materials (e.g. plastics, metals, etc.) from the mixture. This process, however, generates also a physiological amount of fibres that are wasted along with non-fibrous materials, causing inefficiency from an environmental, but also economic point of view. In 2018, the Group decided to install the separation system “Tiger Depack® PPS” at the Santa Giustina (Italy) mill to recover the fibrous material present in the pulper waste that the pulperization phase failed to separate from the poly-component materials (e.g. laminated boards). The result is a reduction in the amount of fibrous material present in the pulper waste from 20% to 5%. It is not surprising that during the “Waste Forum” organized by “Legambiente” and “Ricicloni Veneto” Municipalities in November 2018, the mill of Santa Giustina received a special mention for “Circular Innovation” thanks to the Tiger Depack® PPS technology. The latter manages indeed to separate the cellulosic fibres, generating a clean plastic waste that can thus potentially be used for new applications.

Innovative features:
The fibre recovery system allows to obtain a pulper waste that features a limited presence of fibrous material. The waste characteristics are such as to allow its recovery, avoiding thus the transfer to landfills or to waste-to-energy plants. Moreover, the development of downstream practical applications would allow a complete exploitation of urban separate waste collection: in addition to the high efficiency recovery of fibres (which is already in place), it would be possible to reuse the plastic waste and the other impurities contained in the urban waste paper for a potential goal of "zero waste in landfills".

The paper mills producing paper for corrugating from paper for recycling, in order to use this raw material must separate it from the many impurities present there that can not be reused in the production process. These materials, plastics, polystyrene, wood, fabrics and other materials are to constitute the waste of the pulper, a non-hazardous waste classified under code CER 03 03 07. In addition to these materials in the waste of the pulper there is also paper fiber that is discarded by the process both for normal loss due to the efficiency of cleaning machines, both because it is not easily pulpable and therefore not made usable in the process in normal pulping times. The plant consists of a belt that feeds the waste, as produced by the pulper, to a hopper-shredder that has the function of both reducing the size of the pieces of plastic and dosing the material as consistently as possible. The material itself then passes into a large reactor with two vertical agitators that have the function, with the help of process water, to "weaken" the plastic-fiber bond and to begin the separation, on the principle of gravity, of heavy bodies. After the reactor, a rubber belt of particular conformation transports the plastic and the fibre into a horizontal axis centrifuge cylinder with holes of appropriate size. The material, when the cylinder is rotating strongly, is completely separated and, while the water and the fibre pass through the holes and are recovered in the process, the plastics and the other larger components are directed to a press and constitute the outgoing flow of clean plastic.

Innovative features:
The innovative aspects of the project are many: one is certainly the synergy between technologies applied in the field of plastic reuse and plants for the treatment of waste paper pulper with recovery of raw material. With regard to the plant, the innovation is not so much in the individual sections of it, even if the so-called reactor, the heart that separates the plastic from the fiber, has a very particular conformation, but in having assembled them with technical solutions effectively new for the paper industry in order to obtain a difficult result (complete separation of the fiber from the plastics) with few machines, low energy consumption and especially the use of a wet technology efficient even with recycled water such as not to have increased by one liter the consumption of fresh water of the plant. Also the further study developed on the fraction of clean plastics to be able to classify them as "end of waste" or "by-product" such as to exclude them from the waste legislation is an important innovation that could have interesting effects and developments for the whole paper sector.

Over the last years, within a broader innovation and differentiation strategy, Sofidel has been working in developing new products, striving to meet customers and consumers’ new needs. In particular, the Group is committed to further reducing its environmental impact also developing more sustainable packaging by limiting the use of conventional plastic, to help fight pollution from mismanagement of that material. The new Rotoloni Regina Eco line joins the traditional product range and represents another step towards sustainable development by the Sofidel Group. Rotoloni Regina Eco, which retain the same product quality that Italian have learned to love over the past 30 years, are now packaged in kraft paper – a plant-based material that is renewable, biodegradable and easy to recycle – instead of standard polyethylene film. They are also manufactured using electricity from 100% renewable sources, generated at the Sofidel production plants. As part of a broader vision, the overall goal set by the Sofidel Group is a 50% reduction in the use of conventional plastic in its production by 2030 (compared to 2013). In particular, Sofidel undertakes to eliminate the equivalent of 600 tonnes of plastic a year from the product packaging of its main European brands (including Regina, Cosynel, Nalys, Le Trèfle, Sopalin and KittenSoft) by the end of 2020.

Innovative features:
• Product wrapped with kraft paper • Manufactured using electricity from 100% renewable sources

Thanks to the commitment of Lucart in the search for ecological and innovative solutions to reduce the environmental impact, the Natural line products (obtained from the recycling of cellulose fibers contained in Tetra Pak type beverage cartons) are now in recycled and recyclable paper packaging (produced in the Lucart Group plants) for a more sustainable choice. A major element of innovation is being able to boast a primary packaging made of recycled and recyclable paper printed with compostable and biodegradable inks. The Natural product line has thus achieved a completion of the Circular Economy project that Lucart has been pursuing for decades.

Innovative features:
Tissue paper products from the Natural line were launched on the market in 2010. It was a real product innovation as there was no tissue product on the market that derived from the recycling of Tetra Pak type beverage cartons (material that risked being disposed of in landfills). Today, in order to pursue the Group's objectives of reducing the number of wrapping plastics, the Natural line products are no longer packaged in plastic but with paper packaging (recycled and recyclable). In support of the innovation element, it is possible to boast a primary packaging made of recycled and recyclable paper printed with compostable and biodegradable inks. The sustainability path continues that saw Lucart boast the first Ecolabel certification in Italy in the tissue market and on this path we can boast of being forerunners with this new project. The project is also expanding because in addition to intervening in the primary packaging (paper wrapping the rolls) we also modify the secondary packaging with the intention of replacing the current plastic with a recycled derivation.

Essity, which has made sustainability one of its pillars, has designed a project, in symbiosis with FAVINI, that shows effectively how a company can work in the context of a circular economy. Essity manufactures high-quality tissue paper by reusing secondary raw material coming from the agro-industrial sector – for example the orange peel, corn-cob and skin coffee bean leftovers that, otherwise, would be going to disposal. This material can replace the virgin fiber coming from trees up to 15% and its origin is wholly Italian. In this innovative process this secondary raw material is given a ‘second chance’ as primary source for the production of high-quality, eco-friendly tissue paper. Essity is able to both reuse sources destined to scapping and reduce at the same time its impact on forests, in a virtuous cycle. Essity uses this innovative idea to produce napkins, kitchen rolls, hankies and toilet paper, all biodegradable, biocompostable and 100% Italian.

Innovative features:
Reuse of raw material from agro-industrial cycles - UPCYCLING Saving of pure cellulose fibers without impacting the total quality of the finish product Opportunity to give value to an Italian supply chain Offer an opportunity to manage material before it is scrapping A natural appearance of the product based on the material used

Bartoli spa has recently developed a molded fiber plant for the production of disposable tableware made out of virgin pulp, creating Naturanda® the new consumer division. A new range Colors has followed the standard white product line, an absolute worldwide novelty. Using renewable virgin wood fiber, jointly with virgin pulp from sugar cane and the post-consumer – where the product can be sent to the waste paper cycle thanks to Aticelca certification A and A+ or to the organic cycle having a TUV OK Compost Home and OK Compost Industrial certifications - make Naturanda® an excellent alternative to the plastic single use tableware. Furthermore, thanks to an efficient production process and a deep survey on virgin fibers mix it has been possible to realize an Ecodesign line, where the weight of single product (plate) has been reduced of 20% in comparison to the competitors, keeping the same mechanical properties of the products. The product, thanks to innovative thermoforming process, it has a very high rigidity and it can be used in the electric oven as well as in microwave one.

Innovative features:
The line of colored Cellulose pulp plates is an absolute worldwide novelty. From the use of 100% renewable raw materials (vergin wood fibers, including sugar cane fibers) to post-consumer, where the product can be sent to paper collection (Aticelca A and A + certification) or to the organic fraction (certification Tuv OK Compost Home and Industrial), Naturanda® is a valid alternative to plastic single use tableware. Moulded pulp plates have high mechanical strength, cutting resistance and they can be used for hot food. White plates can be used in the traditional or in the microwave oven.

SICEM SAGA is a producer of pulp, selling in Italy, Europe, Middle and Far East. Raw materials come from national poplar plantations and about 70% of pre and post-consumer wood.In this absolutely innovative circular economy project, the wastewater, currently treated in a conventional aerobic plant, will be used as a substrate for an anaerobic process for the production of advanced biomethane. Main results will be:• Polluting load per product unit will be reduced. • Wastewater will be treated and purified in completely closed reactors, significantly improving the impact on the close environment. • The specific production of waste (such as excess sludge and carbon dioxide) will be dramatically reduced. • The obtained high quality biomethane will be completely sustainable, helping to reach the objectives of greenhouse gases reduction, energy recovery and circular economy. Furthermore, in this case no further dedicated raw materials will be required. • Reduced specific resources consumption will be obtained, e.g water cycle in the pulp production process will be further closed.The project has already been validated at pilot scale, through a more than 6 months experimentation, showing the efficiency of the technology in reducing the organic load of the waste water and producing more than 100 cubic meters of advanced biomethane.

Innovative features:
This is the first project in Italy for the production of advanced biomethane, from industrial waste water, for the injection in the transport public grid. Selected digestion technology is a great improvement of traditional anaerobic treatments, using dedicated granular microorganisms with high selectivity towards methane production and completely recyclable within the process. Moreover, the membrane processes selected for the purification of biogas are very recent, and are simpler and less energy consuming than traditional water or chemical absorption.
