Posting this just to show you what user office looks like. You can see how much waste you have got, your quota which is very important and, of course, the cost of your goods. Every time you refresh a page, the price of your goods is different, because it shows live stats.
Your 25% share is not very important if you are the beginner, however, if you are planning on making a lot of money that will have a big impact on your earnings. For the start you need to have at least 5000 kg of waste to start going deep into this. So let's forget it for now if you don't have 5 tones of waste.
Goods Volume is what you have in total. This might be your waste and ground material added together. On the right hand side you can see the number of days left before you can restart a cycle or sell your goods.
Tip: If your quota is not higher than 33%, you shouldn't even consider selling your goods, because it's always better to restart a cycle, other wise you'll lose your money.
