THE BWA
The Bitumen Waterproofing Association (BWA) was created to provide an
authoritative voice for the Bitumen roofing and waterproofing membrane
manufacturing industry across Europe.
The BWA is Europe’s central source of advice and information on all
Bitumen membrane roofing and waterproofing matters, both to the
industry and to its user groups. Sustainable and environmental issues
are, quite rightly, matters of great importance to us all in construction. A
full understanding of ideas once rarely mentioned – like ‘global warming’,
‘waste recycling’ and ‘life-cycle analysis’ – is now core to maintaining our
reputation as a responsible industry.
As the voice of the European Bitumen Waterproofing membrane industry,
BWA represents manufacturers who are committed to ensuring their
industry is sustainable and environmentally and socially responsible. It
represents manufacturers who consider that this document –
Environmental Declaration for Bitumen Roof Waterproofing Systems – is
an important step in achieving that aim. This declaration contains key
information to help anyone involved in construction deal knowledgeably
with the environmental impact of the building materials and systems they
specify and use for bitumen waterproofing – be they architects, project
developers, contractors, legislators, roofers or specifiers. This
commitment to environmental issues can also be seen in BWA’s
involvement with several European platforms, like CEN TC 350
‘Sustainability of construction work’ and the publication of a Product
Category Rules (PCR) document for Environmental Product Declarations
of ‘bitumen waterproofing sheets’ as defined in the present ISO and CEN
standards.
BITUMINOUS MEMBRANE
The principal task of bituminous waterproofing is to protect buildings
against water in its various forms e.g. rain, humidity, snow and hail.
Beyond this, its waterproofing qualities preserve and sustain a building’s
capital value. In fact, its ability to protect thermal insulation from rainwater
penetration ensures those thermal properties – the measure of
sustainable economy – will remain effective. Bituminous waterproofing
can also make the roof accessible to pedestrians, even vehicles, and is
the optimal, durable, solution to creating vegetation systems on the roof
that can help keep a building healthy and support biodiversity.
PARTICIPANTS
Since the environmental impact for the same system is comparable from
one manufacturer and from one factory, to another, BWA decided to
establish a common industry fact sheet that states the average impact
generated by systems that use bitumen waterproofing sheets produced
by BWA members. A total of 42 plants participated to the EPD data
collection phase (see Appendix); the involved counties were: Italy, Spain,
Germany, Belgium, Netherlands, Finland, Sweden, Denmark, Norway
and France. The EPD may not be representative for BWA
members/production locations from other countries.
PRODUCTION PROCESS
Bituminous waterproofing membranes are produced by a continuous
process as outlined in the Figure below.
Raw materials (bitumen and polymers) are mixed separately at a specific
range of temperature and successively reinforced with polyester fleece or
glass mat (Glass mat, glass grid, glass fabric) by impregnation. After
calendering and cooling, the membrane can be finished for practicality
and aesthetic reasons by means of different alternative materials , such
us polypropylene films, (colored) slates, etc. , Membranes are installed
on many different type of building roofs as waterproofing, either, as a
single or multi-layer, depending on the type of selected product.

02 THE MEMBRANE
Single Layer System
Multilayer System
Fully torched
Mechanically fastened
Ballasted
Depending on roof typology, design and building structural variables,
membranes could be installed in three different modalities:
Fully Torched : by heating the bottom surface of the membrane;
Ballasted: the membrane is torched and covered by ballast;
Mechanically fastened: in which membranes are fixed by stainless
steel fasteners and the joints, together with the top layer, are sealed
by torching,
PRODUCT SPECIFICATIONS
BWA has developed, in close co-operation with Life Cycle Engineering
(LCE, Italy), a Life Cycle Analysis (LCA) on-line software tool for all BWA
members, giving them the ability to continuously optimize the
environmental performance of all their bitumen waterproofing products.
Data was collected by means of the customized on-line software tool for
the following six systems.

03 ENVIRONMENTAL PERFORMANCE
CALCULATION
The environmental impact of the six bitumen membrane systems are
calculated at every point in the lifecycle of the systems studied – from
extraction of raw materials, through manufacturing and installation, to
demolition and end of life treatment.
In this LCA, the end of life treatment scenario is based on 68% to landfill,
24% to incineration (without energy recovery) and 8% to recycling.
DECLARED UNIT
The functional unit is 1 m2 installed roof waterproofing with flexible
sheets for roofing which also takes into account the following details:
the installation and maintenance phases (A5 -B5 in the table next right)
are based on a roof of 1000m2 (40x25 m2) as being representative for flat
roofs larger than 50m2, that fulfills as a minimum the national
requirements of country under the geographical scope of this EPD, with a
reference service life of 90 years. The maintenance, in particular,
requires the installation of a new top layer after 30 and 60 years
respectively, as common maintenance operations. This is considered and
included in the eco-profile calculations. More information about
installation and maintenance are available on page 6 - General
Hypotheses adopted.
SYSTEM BOUNDARIES
The processes belonging to the analyzed system were organized
according to following three phases, in compliance with the requisites of
the EPD system:
1. Upstream processes that include: all the impacts due to the
production of raw materials, such as bitumen and polymers as well
as recycled materials, are allocated to this module.
2. Core process that includes: all burdens of the membrane production,
such as energy, direct air and water emissions are taken into account
in this module. Impacts of waste delivered to final disposal are
considered as well.
3. Downstream processes, from the transportation of membranes to
the roof location, to the installation and reroofing phases. The end of
life of membranes and ancillary materials are also included in these
processes.
The unit processes considered in the study are reported in the hereinafter
table to highlight which activities are accounted in the processes. The EN
15804 module description is also reported.

GENERAL HYPOTHESES
ADOPTED ……………………………..
Here the main relevant hypotheses are presented. More details are available on the technical documents mentioned in the references.
UPSTREAM PROCESS ………………………………….
For bitumen, which is the main raw material of the membrane, the Eurobitume Life Cycle Inventory (LCI) was used (available on www.eurobitume.eu). For plastics, Plastics Europe LCI studies were used as reference data. In some other cases, already published EPDs were used (i.e. polyester fleece). No primary data was directly collected from the raw material suppliers.
MEMBRANE PRODUCTION …………………………………………
Primary data was collected from the 42 production plants. Data was collected by means of the BWA on-line tool and checked by industrial experts representative of each country involved (clusters). Data was primarily averaged by each cluster and finally delivered to BWA to produce the European average. Data collected by plants is representative of the average technology of each European country involved in the project. The European electricity mix was used as reference data for each production plant.
INSTALLATION & MAINTENANCE ………………………………………………
In the installation phase, the consumption of membrane, including the end of life treatment of membrane waste, is taken into account. The real membrane consumption and the ancillary materials needed for the installation are listed in the table below. Data comes from industry experts interviewed by BWA who have provided information based on their actual process knowledge.

The main phase involved in the downstream process is the reroofing for the renewal stage, in which all activities for the maintenance of the roof are included. This stage was modeled following the hereinafter indications:
The maintenance interval of the systems is every 30 years (re-roofing time). A new layer or top-layer, fully torched on existing system, is placed as renewal processes.
In the System 5, the bottom layer is installed with fasteners regularly placed through the first layer. Top layer is fully torched.
In the System 6, the bottom layer is loose laid and the top layer is fully torched. In case of maintenance the original gravel is re-used without additional treatment.
MEMBRANE END OF LIFE ………………………….………………..
Environmental burden due to waste disposal of membranes is calculated based on an average scenario, which represents the current European situation of this waste typology. The reference scenario considered for the roof membrane end of life waste management is 68% to landfill, 24% to incineration (without energy recovery) and 8% to recycling. For the elaboration of the waste treatment environmental burden, the following hypotheses have been adopted:
Transport to waste treatment: The transportation of membranes to waste treatments were assumed with a lorry 16-32t for the standard average distance of 50 km.
Waste processing for recycling or recovery: for collection of waste fractions it has been considered the transport of waste for 50 km (distance between building site to waste sorting facility). For the waste processing only the electricity consumption of waste sorting facilities has been considered.
Waste disposal: none physical pre-treatment has been considered for roof dismantled membranes but it has been considered their management at the disposal site. Gravel is supposed to be land filled

09 GLOSSARY .
GWP100: Global warming Potential is a measure of potential
contribution to climate change due to the amount of greenhouse
gases (GHG) released by production chain processes. This
contribution is measured in terms of mass of CO₂ equivalent and
is calculated by multiplying the specific GHG emissions (mainly
CO2, N2O, CH4) by the specific conversion factors defined by the
IPCC (www.ipcc.ch). Many protocols are available for its
calculation.
AP: Phenomenon by which atmospheric rainfall has a pH value
below the normal average. It can provoke damage to forests and
agriculture, as well as to aquatic ecosystems and manmade
structures. It is the result of SO₂, of NOx, and NH₃, that are
included in the Acidification Potential indicator (AP) expressed in
moles of H⁺ produced.
EP: Nutrient enrichment of flowing water bodies, which
determines unbalance in aquatic ecosystems due to excessive
flourishing caused by lack of nutrient limitation. The Eutrophication
potential (EP) especially includes phosphate and nitrogen salts,
and is expressed as grams of oxygen equivalent (g O₂).
ODP: Degradation of the stratospheric layer of the ozone involved
in blocking the UV component of sunrays. Depletion is due to
particularly reactive components that originate from
chlorofluorocarbon (CFC) or chlorofluoromethanes (CFM). The
substance employed as benchmark measure for OPD is
trichlorofluoromethane, or CFC-11.
POCP: Production of compounds that foster oxidation due to
interaction with light, resulting in ozone formation in the
troposphere. The POCP indicator mostly encompasses VOC
(volatile organic compounds) and is expressed as grams of
ethylene equivalent (g C₂H₄).
ADP: Abiotic Resources are natural resources, such as iron ore,
which are regarded as non-living. ADP is derived for each
extraction of elements and is a relative measure with the depletion
of the element "antinomy" as a reference.
ADP for fossil resource: The ADP for fossil resource is the sum of
the overall fossil resources extracted for both, material and energy
purposes. It is measured in MJ. Uranium energy is not taken into
account.
