LIFE CYCLE ASSESSMENT.

A Life Cycle Assessment (LCA) measures the environmental impact of a product over its entire life cycle and results in a CO2 equivalent.

For our recycled filament and staple fiber yarns, we perform a calculation of the Product Carbon Footprint PCF (compared to virgin yarns), mainly using primary data instead of relying on databases. The basis for this is the ISO 14040 and ISO 14044 standards.

The data included in the calculation include:
 

  • all substantial raw materials

  • rejects during production

  • packaging materials

  • all transportation

  • energy consumption


The entire production process is modelled by using certified software. Based on the above data, direct and indirect greenhouse gas emissions are calculated, resulting in an honest and realistic carbon footprint of our products (PCF).

We would be pleased to inform you about our important findings, methodologies and values in the context of a closer cooperation.

LCA SERVICE.

Life cycle assessments and especially CO2 balances of products are increasingly demanded by the industry.

However, many companies see the high-priced purchase of LCA software, the lack of data on upstream products, and the lack of internal resources as a major barrier. Hiring expensive services to calculate the LCA is also not an option for many companies.

Carl Weiske therefore offers an additional service around Life Cycle Assessment and calculates your Product Carbon Footprint over the entire value chain of the product.

  • Analysis of the entire product life cycle

  • Collection of primary data

  • Modeling of specific processes

  • Calculation of customer-specific requests

  • Calculation of LCA using certified software

  • Lower price than external service companies

Methodology & Approach

  1. Contractual agreement incl. regulations on confidentiality and data protection

  2. Identification of the relevant production processes

  3. Collection of all input data, if necessary also from suppliers using individual Lifecycle Input Forms

  4. Modeling of the processes using certified software as well as calculation of the CO2 value by Carl Weiske

  5. Creation of a report with a realistic product carbon footprint and listing of optimization potentials

  6. Final consultation

  7. Regular updates of the product carbon footprint
