C.HAFNER stands for: preserving value, conserving resources and acting responsibly.

Sustainability has always been anchored in our company’s DNA. This concerns sustainable management as a company, responsibility for society and in particular for the environment. Against this background, C.HAFNER continuously implements measures to improve the company’s CO₂ footprint. When implementing the measures, we pride ourselves on maximum efficiency and the highest level of transparency.

VERIFICATION

CO2-reduced recycling

In keeping with our tradition, we process exclusively secondary gold – that is, scrap gold from old jewellery, production waste from the jewellery industry and dental waste – which we refine using state-of-the-art processes and renewable energy, thereby minimising our carbon footprint.

Co2-reduced gold

For companies seeking to reduce their climate-related impacts, C.HAFNER offers CO₂-reduced gold as a precious metal solution associated with lower emissions compared to conventionally produced gold.

Traceability in accordance with the RJC Chain of Custody Standard documents the origin and processing along the supply chain. This enables companies to better track emissions across the value chain and to implement measures to reduce their CO₂ footprint without relying on additional carbon offsetting.

THREE STEPS TO CO2 NEUTRALITY

01

AVOIDING CO2

Avoiding CO2 emissions takes priority over all other measures. Second-hand gold means sustainability as it has a significantly smaller carbon footprint than mined gold.

02

REDUCING CO2

C.HAFNER is committed to actively reducing CO2 and protecting the environment by using state-of-the-art technology, recycling processes and regenerative energies.

03

Protect the environment

In addition to measures aimed at reducing the company’s greenhouse gas footprint, C.HAFNER implements further initiatives to reduce its environmental impacts, such as lowering paper consumption.

The highest standards with Scope 3!

C.HAFNER balances according to Scope 3 (in accordance with GHG), which is the highest possible claim to CO2 neutrality! A Life Cycle Assessment (LCA) is a method of summarising environmental effects and making them available as information. Greenhouse gases are balanced according to the rules of the Greenhouse Gas Protocol (GHG).

Scope 1

includes the direct greenhouse gas emissions of a business or company. These include, for example, the annual CO2 emissions of their own heating systems and vehicles.

Scope 2

also includes indirect emissions from energy purchased by a business or company, e.g. through the annual CO2 emissions from purchased electricity or district heating.

Scope 3

also includes indirect emissions within the value chain of a business or company. This relates to purchased goods, such as externally produced preliminary products or chemicals, or services such as external transport.

CO2 REDUCTION MEASURES

To effectively reduce CO2 , we use both process technology and active measures to reduce the company's overall emissions.

  • Using thermal energy

    Heat exchangers feed the residual heat from the refining process back into the heating circuit.

  • Preserving resources

    Raw materials, such as nitric acid, are reprocessed and used in a recycling process.

  • Effective wastewater treatment and filter technology

    Wastewater is treated and any hydroxide sludge produced is recycled. Thanks to the most modern filter systems for exhaust air and wastewater, we not only meet the strict legal requirements but are well below them.

  • E-mobility

    The fleet and company vehicles are gradually being converted into electric drive. The conversion of private cars is being supported by a company-owned charging station.

  • Green Energy

    In both of our plants, we predominantly purchase green electricity from renewable energies - recycling plant: 100%; production & administration: 65%.

  • Photovoltaics

    C.HAFNER photovoltaic systems supply 8% of the electricity consumed today. The planned facility at the headquarters in Wimsheim will cover 50% of the annual demand in the future. For the recycling facility at the Pforzheim site, a photovoltaic system with 55 kKWp with an annual yield of 66 MWh and a coverage of approx. 20% of the annual electricity demand is being planned.

  • Energy efficiency measures

    We take numerous measures to reduce energy consumption, such as:

    1. Using timers for electric ovens in production and for ventilation systems
    2. Switching off facilities during the night
    3. Secondary machine cooling via free cooler
    4. Limiting heating temperatures to 21°
    5. Using economical LED lighting (currently 80%)
    6. E-bikes for employees
    7. Reducing paper consumption
    8. Sending invoices online
    9. Reducing flying and travel via online meetings
    10. Biodegradable shipping bags
”

For C.HAFNER, sustainability-related action involves a holistic analysis and continuous development of our processes, with the aim of systematically reducing emissions and gradually lowering the company’s CO₂ footprint.
