LCA & material health results & interpretation Small Profile High-Efficiency Urinal UT105U(V)(G)

Scope and summary

  • Cradle to gate
  • Cradle to gate with options
  • Cradle to grave

Functional unit

10 years of use of a urinal in an average U.S. commmercial environment. One urinal in an average U.S. commercial environment. The period of 10 years is modeled as the period of application based on the average technical lifespan for commercial applications. The economical lifespan of commerical applications can be longer or lower due to aesthetic replacements or more intense use. The implication is that the LCA model assumes that the application ends at year 10 and that the materials will be treated in an end-of-life scenario.

Default use phase scenario

10 years of service in an average U.S. commercial environment with 0.125 gallon/use and 18 uses/day during 260 days/year resulting in 5,850 gallons of water.

What’s causing the greatest impacts

All life cycle stages

The production stage is dominating all impact categories. Results show that the use stage is less dominant than the production stage, yet it is still significant in most of the impact categories. This is mostly due to the embedded energy arising from acquisition, treatment and distribution of the water used during the operation of the product (4-26%). The contributions covered under the construction/installation stage are mostly associated with the product delivery to the market. The recovery stage includes recycling benefits by preventing the need to produce primary materials. Recycling is a relevant factor for some of the impact categories, offsetting a portion of the impacts caused by production. Additionally, the delivery of the product to the construction/installation site as well as the processes for dismantling the product and final waste treatment during the end of life stage are slightly relevant in the global warming impact category.

Production stage

The ceramic parts dominate all impact categories except for eutrophication, non-carcinogenics and carcinogenics. The brass parts together with the turning brass process have dominating contributions to the eutrophication, non-carcinogenics and carcinogenics impact categories. The remaining parts and processes contribute between 2% and 32% of the overall impacts in the rest of the categories

Sensitivity analysis

There are no sensitivity results that lead to variations greater than 10% in the LCA results.

TOTO programs improving environmental performance

  • Dual-Max®, E-Max®, Tornado Flush, 1G®, and EcoPower® reduce water consumption in the use phase
  • Energy efficiency programs optimize the firing process
  • 50% electricity from renewable energy
  • 100% of post-industrial ceramic waste is recycled

*Installation and deconstruction/demolition are mostly manual. The toilets and/or urinals should not need repair, maintenance or replacement during the modeled life time.

Operational energy use is irrelevant to the life cycle of the modeled product.

Reuse and energy recovery are not modeled for toilets and/or urinals.

Ecological damage

Impact Category Unit
Acidification kg SO2 eq Kilograms of Sulfur Dioxide equivalent
Acidification processes increase the acidity of water and soil systems and causes damage to lakes, streams, rivers and various plants and animals as well as building materials, paints and other human-built structures.

Ecotoxicity CTUe Comparative Toxic Units of Ecotoxicity
Ecotoxicity causes negative impacts to ecological receptors and, indirectly, to human receptors through the impacts to the ecosystem.

Eutrophication kg N eqKilograms of Nitrogen equivalent
Eutrophication is the enrichment of an aquatic ecosystem with nutrients (nitrates and phosphates) that accelerate biological productivity (growth of algae and weeds) and an undesirable accumulation of algal biomass which impacts industry, agriculture, drinking, fishing and recreation and causes death of fish and shellfish, toxicity to humans, marine mammals and livestock, and reduces biodiversity.

Global warming kg CO2 eqKilograms of Carbon Dioxide equivalent
Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere, which can contribute to change in global climate patterns and is caused by the increase of the sources of greenhouse gases and decrease of the sinks due to deforestation and land use. GW leads to problems in human health, agriculture, forest, water source and damage to species and biodiversity as well as coastal areas.

Ozone depletion kg CFC-11 eq Kilograms of Trichlorofluoromethane equivalent
Ozone depletion is the reduction of ozone in the stratosphere caused by the release of ozone depleting chemicals. Ozone depletion can increases ultraviolet B radiation to the earth which can adversely affect human health (skin cancer and cataracts and immune-system suppression) and other system (marine life, agricultural crops, and other vegetation) and causes damage to human-built materials.

Part B: Product Group Definition – Commercial Urinal

Transparency Reports™ / environmental product declarations enable purchasers and users to compare the potential environmental performance of products on a life cycle basis. They are designed to present information transparently to make the limitations of comparability more understandable. TRs/EPDs of products that conform to the same PCR and include the same life cycle stages, but are made by different manufacturers, may not sufficiently align to support direct comparisons. They therefore, cannot be used as comparative assertions unless the conditions defined in ISO 14025 Section 6.7.2. ‘Requirements for Comparability’ are satisfied.

Rating systems

The intent is to reward project teams for selecting products from manufacturers who have verified improved life-cycle environmental performance.
