Environmental Monitoring Systems
Monitoring the airCimentos Liz has an environmental monitoring program with the goal of systematically following the results of atmospheric emissions at the sources – the stacks. Cimentos Liz has an environmental monitoring program with the goal of systematically following the results of atmospheric emissions at the sources – the stacks. For that purpose, opacimeters that measure the concentration of dust at the outlets of the exhaust stacks operate 24/7 at strategic spots such as: bag filter installed at the clinker kiln, at the rawmill and solid fuel grinding processes, at the clinker cooler, at the cement silos, among others. Equipment like the Hi-Vol sampler that monitors the Suspended Particulate Matter (SPM) and the PM-10, comprise a set of monitoring stations that manage the quality of the air in the cities of Vespasiano and Lagoa Santa. Measurements are taken by specialized firms and the results are analyzed by the state environmental authorities. |
Noise MonitoringTo monitor those noises produced by our operations, Cimentos Liz has three reference points located in the proximity of the Plant to measure the level of environmental noise, in compliance with Brazilian norms (NBR). In the case of those noises generated by rock extraction at the quarry in Lagoa Santa (MG), Cimentos Liz takes measurements at the nearby city districts during every event, and the data are sent for assessment by the environmental authorities. Water MonitoringIn order to monitor the quality of water, Cimentos Liz collects samples from the Ribeir‹o da Mata river, which runs through the PlantÕs property. Monitoring stations are installed upstream (at the site where the creek runs into the companyÕs land) and downstream (at the site where the creek leaves the property). The quality of water in the artesian well is analyzed in detail. The quarrying activity is also an integral part of the underground water quality monitoring program for which piezometric wells are used.

CO-PROCESSING
The co-processing technique has existed since the Ô70s and is used to destroy industrial waste in a definitive and responsible manner without leading to any type of environmental liabilities.
Empresa de Cimentos Liz has utilized this technique since the year 2000 and has, at the same time, reinforced its commitment to the Environment and its respect for both federal and state Legislations that govern this activity.
The process consists of transforming the waste that is to be co-processed in kilns, at a temperature as high as 1600⁰C, into energy and into components that will be added to the clinker, an essential product for the production of cement.
Co-processing offers innumerous advantages such as the safe and definitive elimination of waste without the generation of byproducts, the reduction of CO2 emissions, the constant monitoring of operations and a reduction in the use of nonrenewable natural resources.
Conama Legislation 261, of August 26th, 1999 is enforced throughout the entire country and establishes the criteria for co-processing activities and determines which materials may be co-processed. On the other hand, State Legislation, norm deliberation 154, furnishes those provisions that restrict issues regarding co-processing in the state of Minas Gerais.
