Introduction

Bio-based products from forestry and agriculture have a long history of application, such as paper,

board and various chemicals and materials. The last decades have seen the emergence of new bio-based

products in the market. Some of the reasons for the increased interest lie in the bio-based products’

benefits in relation to the depletion of fossil resources and climate change. Bio-based products may also

provide additional product functionalities. This has triggered a wave of innovation with the

development of knowledge and technologies allowing new transformation processes and product

development.

Acknowledging the need for common standards for bio-based products, the European Commission

issued Mandate M/492 , resulting in a series of standards developed by CEN/TC 411, with a focus on

bio-based products other than food, feed and biomass for energy applications.

The standards of CEN/TC 411 “Bio-based products” provide a common basis on the following aspects:

— Common terminology;
— Bio-based content determination;
— Life Cycle Assessment (LCA);
— Sustainability aspects;
— Declaration tools.

It is important to understand what the term bio-based product covers and how it is being used. The

term ‘bio-based’ means 'derived from biomass'. Bio-based products (bottles, insulation materials, wood

and wood products, paper, solvents, chemical intermediates, composite materials, etc.) are products

which are wholly or partly derived from biomass. It is essential to characterize the amount of biomass

contained in the product by, for instance, its bio-based content or bio-based carbon content.

The bio-based content of a product does not provide information on its environmental impact or

sustainability, which may be assessed through LCA and sustainability criteria. In addition, transparent

and unambiguous communication within bio-based value chains is facilitated by a harmonized

framework for certification and declaration.

The purpose of this European Standard is to provide a method for the determination of the bio-based

content of solid, liquid and gaseous products, based on the accounting of materials entering and leaving

the system and on traceability of the materials during processing, to ensure the physical presence of the

bio-based material in the output.

Although it is not the purpose of this method, the claimed bio-based content of the output could be

validated by analysis using EN 16785-1 [1].

1) A mandate is a standardization task embedded in European trade laws. Mandate M/492 is addressed to the

European Standardization bodies, CEN, CENELEC and ETSI, for the development of horizontal European

Standards for bio-based products.

EN 16785-2:2018 (E)
1 Scope

This part of EN 16785 specifies a method of determining the bio-based content in products using the

material balance applied to a representative product batch in a production unit.

This European Standard is applicable to any solid, liquid and gaseous bio-based product containing

carbon, obtained by chemical synthesis, mixing or assembling, provided that:

— for a product batch, the composition of the product and the bio-based content of each input, output

and loss in the production unit are known; and
— the bio-based content of the product is verifiable by analysis.

This method incorporates only the physical parts of the input and output stream as present in the final

product, and does not incorporate material inputs for the energy to be used during the production

process.

This method is not needed for the determination of the bio-based content in natural products wholly

derived from biomass.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

EN 16575, Bio-based products - Vocabulary
3 Terms and definitions

For the purposes of this document, the terms and definitions given in EN 16575 and the following apply.

3.1
material balance

comparison of physical quantities, expressed by mass, of inputs and outputs for a product in the

manufacturing process of this product, over a specified time period
3.2
product batch

identified collection of products, manufactured consecutively or continuously under the same

conditions, using the same materials conforming to the same specification

Note 1 to entry: The product batch is defined and identified by the product manufacturer.

3.3
representative product batch

product batch assumed to have the same characteristics as the production sampled when the latter is

considered as a homogeneous whole

SIST EN 16785-2:2018
EN 16785-2:2018 (E)
4 Principle

For a defined product batch manufactured in a defined production unit, this method, supported by rules

described in Clause 6, consists of:

a) the quantification of the inputs, by dry mass, of the materials used for producing the bio-based

product under consideration;

b) the quantification of the losses, by dry mass, in the production unit, for each lost material, if any;

c) the quantification of the output(s), by dry mass, and
d) the calculation of the bio-based content from these data.

The traceability system of the production unit provides necessary information and data to perform the

calculations.

This method requires that the bio-based content of each input and lost material for the defined product

batch in the production unit is known.
5 Natural products

It is not needed to apply this method for the determination of the bio-based content in natural products

wholly derived from biomass [e.g. wood (including pulp), flax, hemp, bamboo, sisal, coconut, rice].

The bio-based content of a natural product or constituent of a product is equal to 100 %.

6 Rules for allocation of elements

For a product or constituent of a product obtained by chemical synthesis, the following rule shall be

applied:

a) if the reactants are exclusively derived from biomass, the bio-based content of the product or

constituent of the product is 100 %;

b) if none of the reactants is derived from biomass, the bio-based content of the product or constituent

of the product is 0 %, and

c) if the reactants are derived from both biomass and non-biomass, the following convention applies:

If oxygen (O) and/or hydrogen (H) and/or nitrogen (N) element(s) is(are) bound to a carbon

structure derived from biomass, its(their) fraction shall be considered to be part(s) of the bio-based

content.

NOTE 1 According to the current state of the art, it is not possible by isotopic measurements to establish a

distinction between elements originating from biomass and elements originating from non-biomass, for elements

such as oxygen, hydrogen or nitrogen.

NOTE 2 Element(s) other than C, H, O and N are not considered in this European Standard.
