CO2 and air pollutant emissions from biocoal briquettes
EFs of CO 2 and air pollutants (including CO, CH4, NO and PM ) are presented in Fig. 4, and a summary of the data is detailed in Table S2. As seen, CO 2 emissions for the three biocoal briquettes were obviously ( p< ) lower than that for the bituminous briquettes, and close to that for the anthracite briquettes.
