Modelo de cuantificación Construction and demolition waste (CDW) • Example Origin: Brick Wall (m²) = 630 m². Destiny: m³ ceramic waste. * Bricks dimensions: ? 24,00 x 11,50 x 7,00 cm³. * Change in volumen 30%. * Percentage that becomes waste 100%. 14
Modelo de cuantificación Construction and demolition waste (CDW) We are demolishing 630 m2 of a brick wall 15
Modelo de cuantificación Construction and demolition waste (CDW) 630 m² . CC = 0,1150 m³/m² Volume = 630 x 0,115 = 72,45 m³ pn 16
