The figures are contained in the annual State of the Environment Report, released on Tuesday, which further found that 83 percent of all waste is not separated by people before its disposal.
Last year, land-filling of biodegradable municipal waste increased to 43 percent, two percentage points more than in 2016.
“This increase was in line with the growth in consumption, but was not accompanied by an increase in differentiated separation”, according to the Portuguese Environment Agency (APA), which issued the document.
Provisional data for 2017 indicates a 21 percent increase in total eco-value revenues (revenue generated by waste treatment manufacturers) to about €101 million.
This behaviour is due to “the coming into force of a new generation of allowances for systems of specific waste flows, which give management entities increased obligations to increase management transparency and reduce the recovery value of various materials”, explains the APA.
The number of products placed on the market has declined to 1.3 million tons, 20.6 percent less than in 2016.
The APA further states that producers and importers paid, on average, for the year 2017, around €76 per ton of product placed on the market.
The values furthest from averages were the flow of used tyres (€ 142 per ton) and end-of-life vehicles (€1 per ton).
