Environmental Performance


We take our environmental responsibilities very seriously, with close monitoring of the impact of our operations daily. Our goals are optimal production with effective management of emissions and efficient use of energy and raw materials. Through our Geocycle waste management team we are contributing to the removal of harmful wastes from society and the elimination of environmental risks associated with over-pressed landfills and illegal dumping.

We are pioneers in the region for the development of waste solutions and renewable resource utilisation. We were first to develop a destruction facility for handling ODS (Ozone depleting substances) including highly harmful CFC gases. We operate the largest biomass alternative fuel project under the UNFCCC's Clean Development Mechanism, and a first of its type for Holcim worldwide. In substitution for burning coal we use discarded rice husks and palm kernel shells, which otherwise would give off large amounts of CO2 emissions in natural decomposition. This is not only a contribution to saving coal stocks, but provides economic opportunities for local businesses to develop earnings from the regular supply of biomass.

We manage cement dust dispersal through electrostatic dust precipitators, we are cultivating fast growing trees in fuel forests to act as carbon sinks around our plant sites and we are reducing both the clinker level in final cement (saving heat and CO2 emissions) but also water usage and electricity per tonne of finished cement. Close attention is also paid to noise abatement.

Greening & Rehabilitation

Re-greening and land rehabilitation is ongoing throughout our operations. In 2012, we planted 51,000 trees around our operations on Java, and rehabilitated over 160 hectares of a former quarry. We established deer, bird and butterfly breeding sanctuaries in our Cilacap plant and Jeruk Legi quarry, and increased the tree species planted in the 46-hectare Cilacap city forest.

In 2010 we began a biodiversity study with conservation group Flora & Fauna International into the high-conservation forests on the 11,510-hectare Nusakambangan Island, on which we have a 112- hectare limestone quarry. Field surveys identified areas within our mining concession to be protected, and we consulted with local stakeholders on how to conserve the island’s wildlife.

Critically endangered species found on the island include the clouded and spotted leopards, as well as rare populations of eagles, wild boar, monkeys, civets, mouse deer, hedgehogs, armadillos and 23 species of bats – two of which are threatened. Our biodiversity study was completed in 2011 and is to form the basis of a planned island-wide conservation strategy.

The Tuban Expansion

Our Tuban Plant, expected to be operational in 2013, is a greenfield expansion project with coastal access and significant limestone reserves. A full environmental and social impact assessment has been completed and we have already completed two years of detailed community empowerment programmes that are making a difference to living standards, education and livelihood opportunities.
