BRE Environmental Profile
Environmental profiles measure the impacts of a construction material, product or building system throughout its life – not only during its manufacture, but also its use in a building over a 60 year period. This includes its extraction, processing, use and maintenance and its eventual disposal.
VMZINC has been audited and reviewed by BRE Global. The Life Cycle Assessment (LCA) modelling derives a Certified Environmental Profile and a Green Guide rating has been produced.
A wide range of zinc roofing and cladding systems have been audited with the all systems receiving a Green Guide rating of between A+ and A. These profiles can then be applied to the BREEAM (BRE Environmental Assessment Method) allowing VMZINC to contribute to schemes such as the Code for sustainable Homes.
Additional Environmental Aspects of VMZINC Production
Post-consumer content: 17%
Pre-consumer (Post-industrial) content: 30%
Post-consumer content: Most VMZINC building products come from one smelting plant located in Auby, France. The plant uses 17% of recycled zinc to produce all VMZINC building and constuction products.
Pre-consumer content: VM BUILDING SOLUTIONS reclaims all the scrap generated during the manufacturing process. It is the world's number one producer of zinc products for building applications. VMZINC is also the world's largest zinc recycler, a position that reflects the company's goal to provide a "closed loop" for zinc products.
Long Life span
Zinc has an exceptionally long lifespan and has been successfully used for almost two centuries. When VMZINC recommendations are followed and based on empirical evidence, zinc roofs can last over 100 years in many areas.
Low maintenance material
In addition to its long life span, zinc is a low maintenance material. Zinc continues to build a protective layer (patina) over time and will self repair imperfections or scratches.
Zinc production is friendlier to the environment than other metals. For instance it takes much less energy to refine zinc than aluminium, copper, or stainless steel. The energy required to produce zinc from ore is 1/4 that of aluminium and 1/2 that of copper and steel.
Zinc is 100 % recyclable
Zinc is also beneficial at the end of its useful life. Scrap of VMZINC has a high metal content and is 100% recyclable. New zinc products are created from recycled zinc such as zinc oxides used in paint, rubber production, and pharmaceutical products.
Origin of zinc
Zinc exists naturally in water and soil. Many rocks and minerals contain zinc in varying degrees. One third of the zinc used by VM BUILDING SOLUTIONS comes from North America, another one third from Central and South America, and the remaining one-third from other locations worldwide.
Zinc an essential element for life
For humans to the smallest microorganism, animals and plants require zinc for metabolic functions.
In humans, zinc is essential for the proper functioning of more than 200 enzymes, for the stabilization of DNA and the expression of genes, and for the transfer of nervous signals. Zinc is a trace element, as important to the human body as iron, magnesium, or calcium.
In fact, the lack of zinc is a much greater concern than excess. Zinc deficiency can result in several health problems including: skin changes, stunted growth, loss of taste and smell, mental lethargy, loss of appetite, and interference with the functions of the spleen and liver.
"There is considerable evidence that zinc deficiency in humans is a serious worldwide problem…"
-Boston University School of Medicine 1995
"…normal, healthy, non-occupationally exposed individuals are at potentially greater risk from the adverse effects associated with zinc deficiency than from adverse effects associated with normal environmental exposure to zinc."
-U.N. Environment Program Health Criteria for zinc 1996
