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 

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; 

CONTENT OF MATERIALS AND CHEMICALS 

 

Ballasted: the membrane is torched and covered by ballast; 

SUBSTANCES 

Single Layer System 

 

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. 

The main materials that are required for the production of an average

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 m 2 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 1000m 2 (40x25 m 2 ) as being representative for flat 

roofs larger than 50m 2 , 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. 

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. 

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 END OF LIFE 

………………………….……………….. 

 

 

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. 

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 

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.

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). 

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. 

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.
