MSW collection, St.Petersburg |
There are a lot of publications that points out dependence between amount of
waste and GDP. i.e. the more money you have the more waste you produce (consuming increases with incomes increasing). Were there any GRP or GRP per capita decreasing these years? Nope. Look at the figure below - it only grows.
GRP and GRP per capita in St.Petersburg |
So the question "why?" remains. I can only conjecture:
- Changes in measurement system. As you may noticed, cubic meters are measuring units for waste amount. But volume is easily changeable as oppose to weight for solid waste (they measure weight in normal countries), so any changes in measurement affects result. For example they've started to measure weigh instead of volume and then calculate volume for statistics.
- Changes in equipment. Transporters could start to use more trucks with compressing option - volume is easily changeable.
- Illegal transportation and dumping. All this waste avoids statistics. There are over 200 licensed waste transporters (too much to control), but not every one acts completely legally.
