FORMER WINNERS


  • Lactips
    A new plastic made from animal products.

    The French company Lactips manufactures plastic pellets derived from milk protein that is unfit for consumption. This new plastic has the advantage of being soluble in both hot and cold water, printable, produced using existing plastic industry processes (blown film extrusion, injection, thermoforming, etc.) and it also acts as an effective barrier for different gases. It is used to produce flexible films.

     

  • Slimbox
    Customized packages

    Slimbox has invented a machine that manufactures cardboard packaging to fit the size of the product to be transported. This solution reduces wastage, storage needs and transportation costs and provides better product protection. The start-up is already targeting SMEs (30 to 150 parcels / day) and plans to expand into post offices and supermarkets.

    Pili
    Les colorants textiles renouvelables à base de micro-organismes

    PILI propose aux industriels du textile deux gammes uniques de colorants renouvelables issus de micro-organismes : l’une pour les fibres synthétiques et l’autre pour les fibres protéiques. Ces nouveaux colorants, per- formants et compétitifs, permettront à la filière textile de limiter son empreinte écologique grâce à des produits biosourcés. 

     

THE CONTESTANTS


Project presented 

A connected wristband that allows refuse workers to pass on data related to sorting bins. The data is then analysed and interpreted to assist local authorities in optimising their awareness-raising actions. 

The start-up 

Project presented 

New processes for producing biodegradable films. 

The start-up 

Launched in October 2014, InoFib is positioning itself as an innovation platform dedicated to cellulose fibre applications. It operates a technology transfer between producers of cellulose microfibrils (MFC) and potential customers in various sectors such as the paper industry, packaging or composites, with the aim of generalizing the use of this innovative and bio-based material. 

Project presented 

A solution combining two modes of eco-friendly consumption: bulk, and returnable and reusable bottles. 

The start-up 

Jean Bouteille provides food stores (grocery stores, supermarkets, etc.) with:

1) organic liquid food products (wines, oils, vinegars, spirits) and non-food products (shower gels, shampoos, laundry care products, etc.)

2) specialised equipment for the bulk sale of liquid products;

3) glass bottles for foods and reusable bottles for other products 

Project presented 

Lactips transforms milk casein into water-soluble, biodegradable and edible plastic film. 

The start-up 

Project presented 

The publication in open data of information on the collection of household waste at voluntary drop-off points in local communities. 

The start-up 

Open Data Soft (ODS) is developing a data publishing platform designed to facilitate all the operations required for data recovery - collection, sharing and reuse. 

Project presented 

A standard sheet of paper that, without using adhesives, incorporates electronic circuits printed with conductive ink. Papertouch provides an alternative to conventional electronic circuits that use plastic and glues. 

The start-up 

Project presented

The best of plastic and paper in one material

The start-up
Paptic has invented a flexible packaging material made from wood fibre, that also provides beneficial plastic-like properties. Products made from this recyclable and bio-based material are designed for re-use, and it can be used to replace e.g. single-use bags, reusable shopping bags and e-commerce mailers. Its manufacturing process uses 20-30% less water than traditional paper-making processes.

Project presented 

The first range of renewable textile dyes made from microorganisms. 

The start-up 

Founded in 2015 by Jérémie Blache, the PILI start-up is made up of 10 employees (with 4 recruitments of people with scientific backgrounds planned for 2019). Its headquarters are located in Paris and the research team is based in Toulouse. 

Project presented 

'Recycled Park' is a project that consists of two elements: a passive waste trap placed in rivers to recover floating plastics, together with a floating park made from collected and recycled plastic that allows plants and wildlife to become re-established. 

The start-up 

Project presented

Reusable packaging for e-commerce

The start-up
Repack has invented reusable plastic packaging (up to 20 times) for e-commerce. Online purchasers can opt for this innovative solution. On reception of their parcel,  users fold up the packaging and return it free of charge by post in exchange for a voucher. The start-up is partnering with e-commerce sites in Northern Europe and Australia.

Project presented

Customized packages to wrap up parcels

The start-up

Slimbox has invented a machine that manufactures cardboard packaging to fit the size of the product to be transported. This solution reduces wastage, storage needs and transportation costs and provides better product protection. The start-up is already targeting SMEs (30 to 150 parcels / day) and plans to expand into post offices and supermarkets.

Project presented 

Innovative flexible packaging, partially bio-sourced & compostable. 

The start-up 

Created in 2010 in Israel by Daphna Nissenbaum and Tal Neuman, TIPA produces a range of partially bio-sourced and compostable plastic packaging for food (snacks, cereals, dried food, coffee, etc.) and non-food (clothes packaging, zipper bags, stand-up bags). The company employs 30 people. 

Project presented 

Application and connected box to ensure waste is properly sorted and to promote better ways of consuming. 

The start-up 

To improve the sorting process and enhance quality, Eugène revolutionises the way we sort waste at home. A box turns the kitchen bin into a smart object that saves time and money by recycling. For users: transforming the tedious business of sorting into a simple, fun game. For brands: connect brands to their customers all along the consumer pathway, from food shopping to recycling packaging.
