DISPOSAL AND RECYCLING For environmental and safety reasons it is important that users of protective clothing have a garment disposal and recycling programme in place. Many types of uncontaminated and unused garments can be recycled at standard recycling facilities. Contaminated coveralls should be treated as hazardous waste and be disposed of according to the nature of contamination and in accordance with national and local regulations. This will normally entail incineration or other approved method.
Tyvek® is a nonvowen sheet made of 100% High Density Polyethylene (HDPE). It is produced by DuPont de Nemours Luxembourg S.à r.l. Under an environmental policy veriﬁ ed to ISO 140011. DuPont is comitted to the efﬁ cient utilisation of reutilisation of resources and collaborates with designers, converters, manufacturers and others to help them meet their sustainability goals.
For safety reasons DuPont does not recommend the use of reuseable and launderable garments where a limited-use garment of equivalent or higher-performance is available.
1 Virgin, unpigmented Tyvek® can be 100% recycled back into equivalent quality product with no loss of properties or functionality whatsoever. DuPont has been carrying out this recycling process at its manufacturing plants for several decades.
MOST PREFERRED OPTION
LEAST PREFERRED OPTION
Using the right preparatory and processing equipment, used but uncontaminated Tyvek® can also be recycled at facilities accepting grade 2 HDPE. Reclaimed material can be repurposed into new quality products such as garden furniture, milk crates, wall cladding, toys, refuse containers and waste pipes.
If recycling or incineration are not options, Tyvek® can be safely landﬁ lled. Because it is chemically inert and
contains no ﬁ llers, binders or additives, Tyvek® will not leach into groundwater nor release contaminants into the soil.
Subject to local regulations, contaminated Tyvek® can be safely incinerated and, under optimal conditions, will only release water
and carbon dioxide, leaving no signiﬁ cant residues. It can be used a fuel yielding more than twice the energy value of coal , and as much
energy as oil, in terms of BTU rating.
