The invention belongs to the technical field of magnesia carbon
brick production environmental
impact evaluation, and relates to an environmental
impact evaluation method for magnesia carbon bricks and waste magnesia carbon
brick resource utilization products. Firstly, an evaluation object, a function unit and a
system boundary are determined; dividing the life cycle of the evaluation object into a plurality of unit processes according to a
system boundary, and establishing an input and output data
list of each
unit process; a corresponding characterization model is selected, a
list analysis result is analyzed according to characterization factors of the model, and an
evaluation result of the life cycle environmental influence is obtained and represented by environmental influence potential values of different environmental influence types; explaining the environmental influence result of the evaluation object and proposing suggestions according to the contribution degree of each element; then,
investment cost, operation cost and environment
cost calculation is carried out on several
resource utilization paths; and finally, calculating the total income of different waste magnesia carbon
brick resource utilization products, and analyzing the total economic benefit.
