Using food waste for dyeing in a DIY workshop in Central, Hong Kong 

Lol

This is not true but very short minded The colour you buy has to get produced too As a consumer you do not see the whole process behind the colour you buy Colour extracted from food can be sold the same way so the consumer as you will not see any difference

@@wongogubongo8844 Yes thank you very much for explaining the difference... "You do not see the whole process behind the color you buy". Exactly why this video is interesting for people to see. You have explained it yes... Otherwise this would have no significance. If this was prepared and made in some factory nobody would buy it because 1. it is not efficient 2. expensive 3. no filters and small scale production means a lot of fire and energy for very little color. But yeah... here we can see how he does it so we feel cool about it... so hipster right? Just give me a break... This has nothing to do with ecology...

@@TeacherFlash for the last thousands years it was efficient enough until today What he is doing is not a new miracle science but known since nearly ever If you are in pastel tones or easter eggs this is what you use until today What do you want to filter? Its just food and non toxic You think it is not efficient because he is using foodwaste instead of new resources? Yes he is doing it in a small scale.. this can chance any time and get combined with other production steps like bio fuel or fertilizers from foodwaste, i think its just you thinking in a smal scale So he is trying some stuff, its normal to do this in a small scale Before the international space station or the first man on the moon they did just send some dogs to space... with your logic they should have sent the whole menkind to the moon just to test if it works? To be honest i think your just ranting.. maybe you are working in a paint company and fear to loose your job or mere likely you are a shareholder... this guy will shred your worthless bitcoins.. haha

@@wongogubongo8844 Okay you are right... a man cooking in his kitchen is just as efficient as a factory with filter systems on its chimney and waste water recycling systems and large scale optimization of the production and energy spending. You are right... I take back what I've said.

@@TeacherFlash if filtering is as efficient in his kitchen or in a factory... what does it matter? What exactly do you need to filter? If you want brown easter eggs you boil the skin of onions put the egg in this water that looks like tea and if you take the boiled eg out it is brown Its non toxic at all, its done with foodwaste, it does not need additional resources, if you like it you can drink the water unfiltered, if you dont like it you can use the rest in a bio feul composter There is nothing to filter at all... factory or kitchen... what are you trying to filter? If you take the red beetroot... what do you try to filter... its just red juice as in a salad... eat it, drink it, or use it to make your clothes red There is nothing to filter

Why?

You eat Out of the rest you extract colour The rest you use as fertiliser Just because you extract some colour the waste does not disappear magically
