Where can you take your recyclables? There are two maps from two websites that I have been using. I find atkritumi.lv very informative and most of the times the bins are actually there where they mention them. On the left hand side of that website you select the type of waste you are interested in and than select the district of the city you live in.
This map from L&T company is pretty good and you don’t have to select each of the type separately they show you straight away on the map which bin are where.
Also if you are outside of Riga or there aren’t any bins near by and you live in a private house, you can order them through L&T company. Obviously, you would have to pay a fee depending on the amounts of waste that is required to be collected.
