Radici Plastics Source of Recycled Polyamides
Waste from Radici Chimica polymerization plants and
Radici Yarn spinning plants are used as raw material for
post industrial compounds

Radici Plastics Source of Recycled Polyamides
Main Sources of Radici waste :
• Off-spec polymers
• Fibers scraps
• Polymerization scraps
Radici Post Industrial compounds sold
with Heramid® brand in all industry
sectors
Specific grades developed and sold
for the automotive industry. Some of
these grades sold with Radilon®
brand (the trade name of Radici’s
prime grades)

Use of recognized and certified methods for the
'analysis of the environmental impact of its materials
from "cradle" to “gate”. This approach is an integral
part of the Radici Group's policy aimed at improving
the "environmental performance" of its products and

The function provided by the products to compare,
the data and metrics, are governed by the Product
Category Rules (PCR) and reported in Environmental
Product Declaration (EPD) implementing the
methodology and performing measures in accordance
with LCA.

Radici Novacips SpA, has become the first company
in Europe to obtain “certificate of conformity” for
its Product Environmental Footprint (PEF).
This achievement represent not only a trial test of
a new methodology for calculating the Product
Environmental Footprint recently introduced by the
European Commission, but also a test of the Sustainability
PCR-EPD
approach
GRI Certified
Sustainability
Report
European Commission, but also a test of the
possibility to draw together defined, well-known
rules with experimental approach.

Radici Plastics has obtained Environmental Statements for the
Radilon® and Heramid® compound certified by an
independent body
(EPD, Environmental Product Declaration + Process
Certification)
Objective :
Connect the technical performance to the environmental
impact, choosing between different alternative formulation
and / or process that can lower environmental impact

Radici’s Eco-Design Approach
- Next to the technical performance, the environmental
performance of polyamide engineering plastics are
considered at the initial stage of product development
- Among feasible alternatives, the formulation with lower
environmental impact may be chosen. EPD certificate canenvironmental impact may be chosen. EPD certificate can
be released on request.
- Selection of the best solution with respect to:
- Environmental impact;
- Recyclability
- Required Technical Performance

RadiciGroup, Officine Maccaferri and
SAMP team up on LIFE-Inno.Pro.Wire
Objective of LIFE-Inno.Pro.Wire: to design an innovative
process and products with a lower environmental impact for
producing extruded steel wire to be used in metal net protection
and containment structures

The sustainability aspect of the project is the use of polyamide 6
(PA6 engineering plastics from the Radilon® range) for coating
the steel wire

Emissions are taken up by atmospheric precipitation called “acid
rain”. This may lead to an increased take up of heavy metals or
reduced take up of some plant nutrients and hence negatively affect
the growth of plants.

The enrichment of bodies of fresh water by inorganic plant nutrients
(e.g. nitrate, phosphate). These typically promote excessive growth
of algae. As the algae die and decompose, high levels of organic
matter and the decomposing organisms deplete the water of
available oxygen, causing the death of other organisms, such as fish.

In the smoke generated from the combustion of oil and its derivatives
are present both unburned hydrocarbons and nitrogen oxides. In the
presence of solar radiation these substances react with one another
to form ozone, considered dangerous for health when in the
troposphere

Destruction of the stratospheric ozone layer which shields the earth from
ultraviolet radiation harmful to life. This destruction of ozone is caused by
the breakdown of certain chlorine and/or bromine containing compounds
(chlorofluorocarbons or halons), which break down when they reach the
stratosphere and then catalytically destroy ozone molecules.
