Sustainability

Both in its manufacture and its application in construction, the Panel is the result of a strong commitment to sustainability, which is the backbone of all the projects undertaken by the Omega Zeta Corporation.

Reducing energy consumption:

  • 61.54% of total consumption has a direct influence on the panel.
  • 51.72% of direct consumption corresponds to machinery, while 48.26% corresponds to lighting.
  • Reduction of energy consumption of machinery 75% using photovoltaic energy.
  • Savings of 90,870 kW/year (based on the dimensions of a curing oven, a post-curing oven and manufacturing machinery).
  • Reduction of 36,348 kg of CO2 per year.
  • Reduction of energy consumption for light of 60% through the use of LED technology.
  • Savings of 60,800 kW/year.
  • Reduction of 24,320 kg of CO2 per year.

0 Waste technology

All waste generated in CIRCA during manufacture of the panel for different works are reused.

The useable petrous waste is ground up and separated from metallic, non-usable waste, and is used to make the panels to meet the aesthetic specifications as well as those of mechanical strength.

Reduction of contaminant gases

The mortar used for the manufacture of the Z Panel has photocatalytic properties, an active principle that can reduce the harmful organic and inorganic contaminants that are present in the air, and preserve aesthetic quality of the finished products over time.

This principle is based on a natural phenomenon in which the photocatalyst brings about the formation of highly oxidising reagents that decompose the organic and inorganic substances that can be found in the atmosphere.

With the application of this material, self-cleaning and decontaminating properties are achieved.

Re-engineering of the production process and the finishing area

As with manufacture, in the production process for the Z Panel processes that help to improve respect for the environment are also implemented. This is achieved by:

  • A reduced number of faulty panels and returns from the client.
  • La reducción de costes de nueva producción.
  • The reduction of new production costs Reduction of the cost of re-producing the panels that have been disposed of as a result of imperfections improving the extraction area.
  • Re-design of the extraction of the panel and the pre-stressing area.

By increasing the size of the uncut panel, consumption by m2 is reduced. This means the assembly area is redesigned to allow for the manufacture of bigger panels, which allows:

  • An increase of 14.3% of manufactured area.
  • Savings of 38,952 kW/year.
  • Reduction of 15,581 kg of CO2 per year.
  • Reduction of the curing time for the exterior layer of the panel.
  • Automated addition of the mortar accelerator to reduce the time required to cure the exterior layer.

Re-engineering strategies are also applied in the finishing area, by:

Automating the production process, which allows:

  • Reduction in energy consumption.
  • Reduction in paint consumption.
  • Reduction in waste panels as a result of poor quality.
  • Elimination of emissions into the atmosphere.

And the introduction of “eco-friendly” products:

  • Commitment to using ecological raw materials.
  • Organic content of less than 5%.
  • Products without biocides, plasticisers, organic solvents or preservatives.
  • Low Volatile Organic Content (VOC).
  • Elimination of toxic fumes during application.

Manufacture from construction waste

In the manufacture of the Z Panel, recycled aggregates from construction waste are used.

These are obtained via different processes for automated and manual cleaning, and classified using trommel screens to sort the non-petrous waste from the material that is suitable for grinding down to make quality aggregates.

This process allows waste to be recovered and used that up until now was discarded due to the difficulties that treating it presented.

The location of the recycling plant near to CIRCA’s production plant means that transport is cost-effective and sustainable in terms of energy consumption.

Self-cleaning constructions

One of the advantages in the construction of the Z Panel that the use of bioelectrophotonics provides is how they imitate the so-called “Lotus effect”, emulating the natural mechanism these plants use to clean their leaves. This consists of numerous tiny crystals made of natural wax that prevent droplets of water coming into contact with the surface of the leaves.

The Z Panel has a built-in nano-coating that effectively reduces the presence of dirt on the treated surfaces while simultaneously making them easier to clean.

Self-maintaining design

The Z Panel is pigmented with KEIM Soldalit-ME, a highly-specialised treatment for façades, with a sol-silicate bases and photocatalytic effects.

In addition to the total protection of the panel, this property allows for the reduction of contaminants in the air, such as nitrogen oxides. The treatment contains a specific titanium dioxide pigment, that acts as a catalyst and, when it comes into contact with light, it can decompose organic and inorganic gases through oxidation processes.

These substances are converted into smaller, harmless compounds that are cleaned by rainwater.

Other features of this paint are:

  • Binding base: Combination of silica sol and potassium silicate (“sol-silicate”).
  • Can be universally applied.
  • With photocatalytic effect.
  • Reduces harmful gases (NOx, COV) and organic dirt.
  • High level of resistance to adverse weather.
  • Stable when exposed to UV rays and acids, anti-static.
  • Alkaline, so free from preservatives.
  • Fireproof (class A2-s1-d0 according to EN 15501-1, and test certificate).
  • Pigments stable when exposed to light.
  • Matt mineral appearance.
  • Breathable, non-film forming, microporous.
  • Very waterproof.
  • No added solvents or plasticisers.
  • Prevents the growth of moulds and fungus, thanks to the optimal management of humidity.

Additionally the ease of reaplication eliminates the need for stripping, one of the procedures that causes the most contamination during the treatment cycle. Advantages and benefits:

  • Unparalleled durability.
  • Great principle of adherence (petrification).
  • Maximum permeability for steam from water.
  • Less mould and fungus.
  • Fireproof.
  • Regulates temperature Unbeaten stability when exposed to light.

Carbon footprint

CIRCA Omega Zeta follows a rigorous Carbon Footprint control process, which measures the amount of equivalent CO2 released directly and indirectly through its activity during the entire production process, up until construction work begins.

All of the different stages of production are considered from the generation of raw materials from natural resources (cradle) and their transportation, to making the product and packaging it (if necessary), up until the moment the Panel leaves the factory (gate). An additional advantage of this is that we can inform our clients about the impact of greenhouse gases associated with the products they use in their building works, allowing them to calculate the carbon footprint that their projects have.

The methodology developed is based on:

  • The ISO 14040:2006 standard Life cycle assessment.
  • The PAS 2050:2008 standard Specification for the assessment of the life cycle greenhouse gas emissions of goods and services.
  • Draft of ISO 14067 Carbon Footprint of products.
  • Draft of the WBCSD/GHG Protocol Product Life Cycle Accounting
 and Reporting Standard.
