Biomass by Ahhaproject

This rubbish bag by Ahhaproject of Milan and Seoul spells out how much energy the user can generate with each bag of kitchen waste collected.

According to graphics on the bags, each full pouch collected for biomass energy production could create enough power to make 100 cups of tea, 500 slices of toast or 1000 boiled eggs.

The information below is from Ahhaproject:


Biomass is a valuable energy resource, which we accrue in large amounts in our kitchens.

But only 40% of this waste in Germany ends up in the bio waste bin. For many people, it is inconvenient to separate the biological waste from residual waste.

A biodegradable bag crafted from PLA material which is easy to use and seal allows an easy replacement and removal of the bio bag.
It visualizes how much energy potential a single bag contains thus forcing us to reconsider Bio-waste disposal habits.

The content of this garbage bag is sufficient to drive 10 kilometers with your car, to do 30 kilogram of one’s laundry, to boil 100 cups of tea, or to use your fridge for 200 hours, to recharge your mobile phone 300 times,to use a energy saving lamp for 400 hours, to toast 500 slices of bread, to cool down 700 liters bear, to make 1000 boiled eggs for breakfast, to shave 10,000 times, to listen to 12,000 hours of music on your mp3 player, or to press out the juice of 20,000 citrons...

    Really puts things into perspective. Hard to believe how little waste can affect things.

  • kerim

    I think the affect can be true. Imagine when the gas explosion from biowaste…
    just my opinion..

    Amazing idea. I hope that it takes this kind of brilliant design to push people into realizing HOW they choose to trash things is important, too.

    PLA material is still way too expensive to be made. any material based on starch/corns is just being unrealistic; you never use food to produce disposable items because there won't be enough land to produce large amount of PLA. (in fact, many forest was cut down because of the ethanol myth).

    based on the "look" of it, it will require a 0.045 micron thickness (which is around twice/triple the thickness of normal shopping bags in the super market), which also means higher the transportation cost.

    The full size printing means high ink cost too.

    The cut out handle is not reinforced, and thus will break easily, PLA is pretty weak in terms of tension.

    So yes, the message is good, but this is more a unrealistic concept. This bag should cost around 500 to 900% more expensive than typical plastic bags. I don't think this bag will be feasible large production.

    All in all, this bag will use up more energy then it can save.

    BRILLIANT idea. and…. you can even take it further, not only write it on the bag….compost = methane = energy = money =….

    What's most shocking is that in the average household virtually everything that goes to the residual waste bin is actually biological waste… so they don't separate just because they're that obtuse. Here in Barcelona biological waste separation was implemented last year and it's sad to see the cans are always half empty but people dump all sorts of bizarre crap on the residual waste bins! Thankfully people do separate paper and aluminium, or at least enough people for the containers to be full.

    This bag is a bit weird, though. Who would buy bags that are more expensive than regular bags to take conscience of something you already know? (because if you buy these bags then it's because you DO separate…)

    Amazing that such a simple concept can have such a huge impact,

    Brilliant idea. Just wondering how big is the bag? What is the maximum weight we can fill the bag with?
