ECOSPECIFIER ISSUES OF CONCERN / RED LIGHTS

Issue of Concern

The cellulose fibre used to make the panel does not come from Forest Stewardship Council (FSC) certified sources, tracking the fibres through the production process. Various timber certification schemes are currently in operation in regards to the sustainable and responsible management of forests as sources of wood. According to ecospecifier, an analysis of the various timber certification schemes reveals that the Forest Stewardship Council (FSC, Chain of Custody) is the most rigorous and robust certification, due to the stringent criteria followed. FSC is the only scheme based on a clear set of minimum performance based criteria, prohibits the conversion of forests to plantations, and also prohibits the use of GMO trees and toxic baiting.

ECOSPECIFIER LIFE-CYCLE ASSESSMENT

 

INTEGRATED DESIGN AND POLICY ISSUES

Internal noise levels can directly affect the comfort of occupants. High noise levels can adversely affect communication between occupants, concentration and hence productivity levels.

Ambient noise levels can be controlled by the addition of sound absorbing products and the minimising of exposed hard surfaces to reduce sound reflection (reverberation) in an internal space.

Specific acoustical performance requirements can be achieved by Au.diLux using a variety of available thicknesses, perforation patterns and acoustic properties. An acoustic engineer should be consulted before specifying requirements for a project.

High durability coming with low greenhouse emissions and embodied energy provide an acoustic panel suitable for harsh environments with minimised maintenance requirements and long term cost savings.

HUMAN HEALTH

Health

Panels contain crystalline silica (approx 10-30% b/w). In 1996, the IARC classified crystalline silica inhaled in the form of quartz, from occupational sources, as carcinogenic to humans (Group 1). This issue of concern relates to the sanding, grinding and other occupational production activities of products containing crystalline silica and is not an issue as installed.

Although fibre cement contains crystalline silica (which has associated human health impacts related to breathing respirable silica) this can only be produced during careless cutting or briefly during production activities, this is not an in-use issue. See ecospecifier Issues of Concern section below for further information on health issues. There are no specific health impacts associated with fabricated product.

Comfort

Acoustic panels contribute significantly to aural comfort due to their acoustic attenuation performance. Product can be specified to meet specific acoustical requirements. The product will also limit reverberation by reducing exposed hard surfaces in an internal space. By reducing ambient noise levels, products can help reduce stress levels and improve wellbeing and productivity.

Indoor Environment Quality

Fibre cement based panels do not contain any components that release VOCs to the internal environment, which is preferable for the indoor environment quality.

Electromagnetic Radiation

Not applicable

Safety

Au.diLuxfibre cement panel contains crystalline silica which is classified as a hazardous substance according to the criteria of Worksafe Australia. If dry-disc cutting is required, appropriate Personal Protective Equipment (PPE) mitigates potential safety issues as outlined in ecospecifier Issues of Concern section below.

Accessibility

Not applicable.

 

ECOLOGICAL QUALITY

Terrestrial

Emissions - The mining and processing of silica can produce emissions to land from surface impoundments of liquids, solids, slurries and from storage facilities.

The production of cement involves emissions to land on-site. This can include solid wastes, slurries, sediments, spills and leaks during the storage and distribution of liquids and may contain National Pollutant Inventory (NPI) listed substances. Emission sources can be broadly categorised as surface impoundment of liquids and slurries and unintentional leaks and spills.

Physical - The sourcing of cellulose fibre from wood pulp generates impacts to the terrestrial environment from forestry, such as loss of topsoil and reduced soil productivity due to nutrient loss.

Extraction of silica results in the removal and stockpiling of topsoil, sub-soil and sand, and from removing overburden and inter-burden, resulting in modified soil/sand profiles, topography and drainage.

Waste material is produced from manufacture of product including - autoclave dry scrap, fine solids from surface finishing, process sludge, other process wastes.

Aquatic

Emissions - The cement manufacturing process generates wastewater from the cooling of process equipment. Pollutants contained in these cooling waters are principally dissolved solids (potassium and sodium hydroxide, chlorides and sulphates) and suspended solids. Wastewater may not always contain NPI-listed substances.

Physical - The extraction of silica sand has associated minor localised physical impacts on physical environments around production facilities.

Atmosphere

Greenhouse (GHG) - Major GHGs are associated with cement manufacture and the extraction of raw materials.

Greenhouse intensity - Ecospecifier has received a report from Branz that has conducted a LCA cradle to gate assessment for Au.diLux products. The Greenhouse gas intensity of the products has an average of 50.0kg CO2e per panel (6mm thick 1200x2400mm sheets) or approximately 17.4kg.CO2 / m2 (6mm thickness) as calculated using cradle to gate LCA.

Transport intensity - Product is manufactured in Hallam, Victoria while the boards come from Rosehill, New South Wales. Transport intensity of 8.6 kgCO2e per panel (6mm thick 1200x2400mm sheets), or approximately 3.0kg.CO2e / m2 (6mm thickness) as calculated using cradle to gate LCA.

Table below provides land transportation greenhouse intensity figures to help calculate the greenhouse gas intensity of land transportation from shipping port.

0.000169 kgCO2e / kg.km

Transport intensity figures sourced from Australian National Greenhouse Gas Inventory 1990, 1995 and 1999 and WWF International, Inland Navigations and Emissions, 2005.

Operational efficiency - Panels are energy and greenhouse efficient in operation as they require minimal, if any, maintenance apart from normal surface cleaning.

Re-use Efficiency - Fibre cement products are recyclable back into fibre cement products by grinding and addition to the mix (as a minor component-and only if not painted) for reforming.  Alternatively, they might also be suitable as a feedstock for cement kilns where the fibre content would (to a small degree) contribute to the firing energy of the kiln and the uncarbonated cement content would reduce the energy needed to calcine the limestone feedstock.

Toxics and Pollutants - The cement production may emit particulate matter, oxides of nitrogen, sulphur dioxide, and carbon monoxide. Trace quantities of volatile organic compounds (including benzene and phenol), ammonia, chlorine, some metals and hydrochloric acid may also be emitted.

Ozone Depletion - No ozone depleting substances are used at any stage in the cradle to gate production of fibre cement panels.

Urban Heat Island Effects - Not applicable

Noise - Panels are for reducing unwanted reverberation within a space, thereby improving the quality of sound in an internal environment.

Biodiversity

The process of extracting mineral based additives, particularly silica and sand (constituent of cement), are sourced as a result of sand mining, a high biodiversity impact process.

Timber and wood products (used for the cellulose) can be among the most environmentally destructive from a biodiversity and ecological quality point of view, due to some forestry practices that lead to the loss and fragmentation of vegetation and habitat for ecological communities.

RESOURCE DEPLETION

Resource Efficiency

Portland cement is manufactured from feedstocks of limestone, solid fuels and waste derived fuels. Silica sand is a non-renewable, but abundant, resource mineral. The cellulose fibre used in fibre cement originates from Radiata Pine, a softwood species and therefore more rapidly renewable than hardwood species.

Resource efficiency is improved by the waste mix slurry from James Hardie's Hatschek process that is recycled back into the fresh fibre cement mixes.

Embodied Fossil Fuel Energy

Ecospecifier has received a report from Branz that has conducted a LCA cradle to gate assessment for Au.diLux products. The embodied fossil fuel energy of the products has an average of 44MJ per panel (6mm thick 1200x2400mm sheets) or approximately 15MJ / m² as calculated by manufacturer using cradle to gate LCA.

While cement has high embodied energy and greenhouse gas generation as a material, the percentage used in fibre cement means that compared to other materials such as hardboard, or brick it is a low embodied energy product on a par with plasterboard.

Embodied Water

Ecospecifier has received a report from Branz that has conducted a LCA cradle to gate assessment for Au.diLux products. The embodied water of the products has an average of 542L per panel (6mm thick 1200x2400mm sheets) or approximately 188L / m² as calculated by manufacturer using cradle to gate LCA.

Durability

Life expectancy is 30-40 years for most applications although no accelerated life testing has been conducted. Product longevity is highly dependent on the installed environment and quality of finish, ventilation (in high humidity environments) and maintenance. Panels installed in exposed high traffic areas may not last as long as panels installed in standard internal ceiling applications. The resistance of fibre cement substrate to most known substances and conditions improves product's durability.

Reusability

Product is mounted with self-embedding screws which are flushed or painted over and is better suited for material recycling than direct reuse.

Repairability

Panels are easily repaired as any holes, scratches or cracks in the fibre cement substrate can be bogged up with standard plastering compounds and sanded and repainted.

Design for Dematerialisation

Not applicable

Design for Disassembly

Au.diLux is mounted with self embedding screws which are flushed or painted over and is therefore not directly designed for disassembly.

Recyclability

Fibre cement products are recyclable back into fibre cement products by grinding and addition to the mix for reforming.  Alternatively, they might also be suitable as a feedstock for cement kilns. Product is mounted with self-embedding screws which are flushed or painted over and is better suited for material recycling than direct reuse, but it is not deemed practical or economical at this point in time because the contaminants from any paints or surface finishes used after purchase, would adversely affect the properties of new products.

There is some potential, however, for use as filling, road base or in low-strength recycled concrete.

Maintenance

No specific maintenance requirements. Maintain in the same manner as standard fibre cement or plaster surfaces.
