Title Specific rates of emission of harmful substances into the atmosphere during the production of rubber shoe soles

Abstract Specific emission rates were calculated on the basis of material balances for each of the 6 operations in sole manufacture; the results are presented in a table. The largest quantity of gaseous pollutants are emitted during vulcanisation (85-95% of the total emissions for the process). Of the 4 types of sole produced, coloured porous rubber gave the largest amounts of gas, black solid rubber the smallest. The average composition of the gaseous emissions was: 1.2% aldehydes, 28% aromatic hydrocarbons (of which 2% styrene), 1.5% amines, 7% naphthenes, 8% normal and iso-paraffins (3-7 carbons), 7.5% normal and iso-olefins, 16% for 8-14-carbon paraffins, 12% for 8-14-carbon olefins, and 20.3% unidentified. An equation was derived for predicting the quantity of emissions from the amounts of natural rubber, blowing agent, regenerated rubber and mineral filler used in the process.
