With MOYU we have an impact calculator made to make it visible and easy to calculate the impact for your business. Broadly, there are 3 main variables that we used to calculate the impact. These are:
1) The savings at production level. The KIWA has conducted an independent study into the impact of stone paper production compared to alternatives.
1 ton 'normal'papier | 1 ton stone paper |
1431 kg CO2 | 474 kg CO2 |
18 trees | 0 trees |
20,2 GigaJoule Energy | 4,31 Gigajoule Energy |
2770 Liter water | 0 Liter water |
2) The savings based on long-term use of a MOYU. Due to the erasable character of the stone paper, the book can last indefinitely, because the paper hardly wears. We've been on the safe side and made an assumption that our MOYU will only last 5 years.
3) For each MOYU purchased, we plant a tree with the local trees for Kenya community. We have this component separatein out impactcalculator .
In order to arrive at the calculations, we have made the following assumptions:
This provides input for the calculator:
1 MOYU |
3,55 CO2 equivalents saved |
0,0675 Trees saved td > |
0.075725 GigaJoule Energy saved | 10,387 liters of water saved |
1 Trees planted |
€30 saved |
We are aware that this is an 'estimated guess' based on the available sources of KIWA, consumption within companies and ope nable price information. Ultimately, the impact is even more in the actual replacement of the notebooks at companies. However, this information will only be visible in a few years after companies have been using our notebooks for a number of years.
If you have any feedback on the above information, we are always open to improvements and conversation!
