5 of the most common questions asked about cardboard

Will a cardboard box decompose?
Cardboard will eventually decompose, but it depends on how tightly the sheets are packed together. In the case of ‘mulch’ being used in a home garden, where cardboard is ripped into shreds and soaked in water and put on flower beds, it can take up to 3 months for it to be decomposed by microorganisms.
Can I put cardboard in the microwave?
We recommend that you never put any flammable material near an extreme source of heat or open flame. Cardboard is no different. You should only ever put dishes and utensils in the microwave if they have been labelled as microwave safe.
Is cardboard bad for rabbits?

Due to its cellulose content, rabbits often like to eat cardboard as it somewhat mimics the nutritional contents of the leaves and vegetables they eat in their natural environment. Giving small pieces of cardboard to your rabbit can be a great way for them to tear, shred and play, which helps with feelings on isolation and boredom if you’re not able to give them much attention in the day.
Rabbit owners must make sure that your pet doesn’t consume too much cardboard, as this will be harmful. Moreover, it’s always best to give your rabbit plain cardboard as opposed to products that have been heavily printed on.
Who invented the cardboard box?
Cardboard has been around for years, the first sheets of which are said to have dated back to 17th Century China. However, the modern day cardboard box as we know it has only been around since 1890, when inventor Robert Gair started producing flat pieces of cardboard sheet that where manufactured in bulk and could be folded into boxes.
Does cardboard float?

Cardboard is a porous material, which means when it is subjected to wet conditions it will slowly absorb liquid. Often times, cardboard may float for an initial period but once it absorbs too much, it’s density will increase above that of water’s, thus making it sink.
