Purebag : Questions and Answers

What is bio-waste?

A bio-waste is a residue composed of organic matter (plant, animal) degraded by micro-organisms. Examples:

  • Vegetables: fruits and vegetables, bread, green waste...
  • Cooking products: tea, tea bags, coffee grounds and its filter
  • Animal products and by-products: meat, fish, egg, dairy products...
  • Biodegradable products from plants: cotton or linen clothing, paper, cardboard...

Depending on its final recovery (composting or methanisation), it is important to know which bio-waste you can or cannot use. See "how to compost"

Why sort my bio-waste?

Today, ecological issues are more important than ever. The European Union and the French government are proposing reforms and solutions to make slow progress. Sometimes too gently.

However, it should be noted that, on the one hand, all companies producing mass bio-waste are now obliged to revalue this bio-waste.

On the other hand, the Energy Transition for Green Growth Act, adopted in August 2015, contains provisions on sorting [...] :

->- ->- deploy incentive pricing for the collection of household and similar waste, i.e. introduce a variable part in the household waste collection tax to reward good sorters (target: 15 million inhabitants covered in 2020, 25 million in 2025, against 5 million in 2015)* ;

In this way, it will very soon be an obligation for all of us to recycle our bio-waste. While some have already been doing so for several years, for others, it is a whole new adventure. A new simple everyday gesture, just as the sorting of glass and recyclable waste has become.

Why not start now?


Why use a bag Pure Bag rather than another?


The bag Pure Bag is to date the only ecological solution to sort your bio-waste.

In fact, another "compostable" alternative has been available for some time to replace the single-use plastic bag, and it is the so-called "starch" bag. The latter is composed on average of 30-40% starch and 60-70% plastic called Polymer. So when you compost it, the plastic ends up in micro-particles in the soil. It is therefore not a viable solution for the respect of the environment. Finally, since this "starch" bag is mainly made of plastic, the latter is not methanizable and is therefore a residual waste in the same way as a plastic bag.

Use Pure Bag will allow you to have in your kitchen a special garbage bag for your bio-waste, moisture resistant and fully compostable or methanizable. If you already use a compost bin at home, using a Pure Bag bag will save you the hassle of having to clean this bin completely every time you empty it. A simple drying process will suffice before putting your new bag in the container.


Although Pure Bagwas first designed to receive your bio-waste, it is important to know that in your garbage can for "household waste", you can also use a Pure Bag rather than your usual black plastic garbage bag.


Because today, 10 million tonnes of residual waste (household waste remaining after sorting) are buried each year in France. This burial in the ground creates unnecessary additional pollution because it is essentially composed of garbage bags.

By replacing your usual bag with a Pure Bag, you limit your ecological impact to a minimum.

What are the sending conditions?

Packages are generally dispatched within 2 days after receipt of payment. We work with Packlink Pro, a parcel delivery service provider who will always offer you the most economical solution to receive your bags Pure Bag either at a relay point or directly at home.

Packages are shipped with a tracking number and delivered without signature. Packaging costs are included in the selling price of the bag. Preparation costs are fixed, while shipping costs vary according to the weight and total size of the package. We recommend that you group all your items in one order. We cannot group two orders placed separately and shipping charges apply to each of them. Your package is shipped at your own risk, however the dimensions of the boxes are appropriate and your items are properly protected.

To meet our zero-waste approach, your packages only contain recyclable and/or biodegradable materials.

To reduce shipping costs, remember to group your purchases with your neighbours or friends !

What are the points of sale?

Pure Bag does not have any sales points to date. However, to avoid shipping costs, you can, with prior request by phone, pick up your bags directly from our company in Cognac. 

What is methanisation?

Methanization is a process that, like composting, uses bacteria naturally present in bio-waste to reuse it.

Methanisation not only creates digestate (a natural fertilizing material just like manure or domestic compost - avoids the use of chemical fertilizers), but also the natural gas produced by this process (methane) is itself revalorized into energy: gas and green electricity!

Contrary to composting, methanisation has the advantage of allowing the recovery of waste such as meat, blood, carcasses, fish, dairy products or any other animal material that cannot be composted at home (because they attract harmful animals such as rats). 

This technique is increasingly used by municipalities and companies. Check with your local town hall to find out if there are collection points near you!

How to methanize ?

Methanisation is currently used by municipalities and companies producing bio-waste. In order to be able to methanize your own waste, you can contact the town hall of your municipality or the nearest waste management centre to ask them if there are collection points (like a glass collector).

How to compost ?

There are several specialized websites that will help you find the best way to compost for you.

If you have a garden

You can install a compost bin directly in your garden. The latter will receive your bio-waste. Once the composting process is complete, you can use it to put on your plates and vegetable garden to replace chemical fertilizers. Economical and ecological !

If you are in town

Many cities provide collective compost bins. Feel free to call your husband to find out where yours is!

You can also make compost at home with home vermicomposters! The latter contain earthworms that accelerate the composting process. By harvesting the "compost tea" (juice at the bottom of the bin), you can water your plants with it, they will thank you for it!

Que composter ?

  • Milled dead leaves
  • Fresh grass clipping
  • Dried herbs

  • Apartment plants
  • Milled pruning wood, sawdust and chips
  • Conifer needles
  • Non-grained weeds, including whole nettle before flowering
  • Vegetable and fruit waste and peelings
  • Crushed citrus fruit skins (little)
  • Rest of meals (without meat or fat)
  • Tea leaves and tea bags

  • Dairy products
  • Plastics, metals, glass (use your sorting bins)
  • Glossy, printed or coloured paper
  • Disposable diapers

What is the composition of the Pure Bag bag ?

Pure Bag is a unique blend of vegetable oils not produced from the production of palm oil and paper from French eco-managed forests. Our paper has obtained the PEFC and FSC labels.

We only work with French producers and printing houses. 

Where are the bags made?

Les sacs Pure Bag sont entièrement fabriqués en Nouvelle Aquitaine. La pâte à papier est fabriquée à la papeterie Alamigeon à Ruelle (16) et le façonnage des sacs est réalisé dans la région de Limoges. Les mises en colis seront effectuées par un CAT local.



How to use Pure Bag ?

Pure Bag is a resistant paper bag, however, it is not invincible because of its biodegradability !

Use for bio-waste

To use Pure Bag, start by unfolding it completely. Place it in the container (compost bin, bin, holder...). Ideally, the container should be ventilated to allow the bag not to store moisture!

Fill Pure Bag with your bio-waste (coffee grounds, peelings, leftovers from meals, tea bags, used tissues, sawdust, stale bread, green waste...). Be careful, however, to remove the wet products from their water by first wringing them out (e.g. tea bag, coffee grounds).

We recommend using it for a maximum of 1 week, so that your Pure Bagdoes not tear when emptying. You can add a little sawdust or litter to the bottom of the bag to avoid tearing when using very moist foods (tomatoes, juicy fruit...). Do not fill your Pure Bagup! This will allow you to fold the top of the bag to close it.

Finally, take your bag in its container and pour it into the container/composer/ etc.

Use for the garbage can

In order to reduce plastic pollution, whether you sort your bio-waste or not, you can also use Pure Bag instead of your black bin bag, in the same way you already use it.

The majority of residual household waste is now buried in France. Thus, by using Pure Bag instead of your usual bag, you allow the burial of non-polluting waste.

How to participate in the Pure Bag adventure ?

Support our project on Kiss Kiss Bank Bank by clicking here !

This campaign de crowdfunfing (= participatory financing) aims to help us overcome the first order costs of pulp and shaping before orders are sufficient to sustain us.

The project Pure Bag has always been studied and developed with funds from the owners of F.C.S.E Environnement. Today, these funds are exhausted and that is why we have created this site and a participatory fundraising campaign to continue the research towards zero waste.
