This is a market activity. Each market represents the consumption mix of a product in a given geography, connecting suppliers with consumers of the same product in the same geographical area. Markets group the producers and also the imports of the product (if relevant) within the same geographical area. They also account for transport to the consumer and for the losses during that process, when relevant.;This market represents the gravel for construction in Brazil, delivered at the consumption point. Transport distance from gravel quarries to concrete block industries was used to represent gravel transportation to construction activities in Brazil (average distance 23,8 km). Gravel is a heavy material and as such, transportation distance must be as low as possible so that the product's price remains competitive. Also for this reason, there are no relevant gravel imports.;Lorry sizes were extrapolated from the market for sand/BR dataset, as the transportation activities of both aggregates are similar.;EURO 3 emission standard (equivalent to PROCONVE 5) is assumed to represent the prevailing Brazilian road cargo fleet (45%), according to the inventory of road transport vehicles in 2013.;Ministry of Environment. 1st National Inventory of atmospheric emissions of road transport vehicles. 2013 http://www.anp.gov.br/wwwanp/images/Emissoes-Atmosfericas-1Inventariodeemissoes.pdf
From gravel loaded into delivery trucks at quarry.
This activity ends with the delivery of gravel at consumption point (manufacturer of construction products or at construction site). |
