New quantification and characterisation of Urban Solid Waste in General Alvear.


This week a new characterisation of the USW will be implemented, in this case, corresponding to the summer season.

The general purpose is to determine the quantity and the types of urban solid waste of Class A and Class B generated in the Department of General Alvear, their physical-chemical characteristics and seasonal fluctuation. Meanwhile, the specific objectives are, as INTI Engineer Martín Reynoso stressed, “to quantify the generation of urban, agricultural and industrial solid wastes that could be assimilated to the urban ones generated in the General Alvear Department and their seasonal variation; determine the material composition of the solid residues generated in the Department of General Alvear and their seasonal variation; determine the potential of the material and energetic valorisation  of the fractions of recyclable and marketable residues; determine the volume/weight of the residues that don't have material or energetic value.”

The proposed work methodology is to implement it in four stages in different periods of the year to get the results and conclusions that would provide reliable statistics on the rates of generation and composition of the present residues and trends. Currently, the second stage is under implementation - the Characterisation and Quantification of Class A and Class B residues.

“The work consists in weighing all the trucks that enter into the Plant of USW, choose some of them randomly and implement a classification of all the materials weighing them separately depending on their type: metals, plastics, wood, styrofoam, cardboard or paper. The goal is to define the characteristics of the USW of Alvear in order to elaborate long term policies of recollection and characterisation of the residues that aim at municipal technological development with the Biodigestor. In relation to that project, the Municipality received the sum of 1400000 $ARS, and the convention with the National University of Cuyo has been signed. This covers 70% of the expenses of the Municipality. The important thing is to determine how the wastes are separated in the households, that is why we encourage all the neighbours to segregate organic and inorganic wastes placing them into separate bags because this facilitates the Cooperative´s work at the Plant” - explained Carlos Pia, the Director of Environmental Management.
