It represents the area of biologically biologically productive land and seaproductive land and sea (biocapacity) that an individual, population or activity requires to provide the resourcesresources it it consumes consumes and to absorb its CO2 and to assimilate associated waste

Biscol processes reduce also this indicator over a half on the average (8,48 / 19,9) and major savings are achieved thanks to pre-treatment phase

Data requirement for finalization of the analyses:

Conventional dyes lab/industrial scale synthesis (chromophore similar to selected bio-dyes)

Bio-dyes lab/pilot plant scale synthesis

Process parameters for the pre-industrial production of bio-dyes

Sensitivity analysis for transport and pilot scale production

Market and estimated costs for Life Cycle Costing Analysis (raw materials, labour, disposal,
