Environmental protection from the outset

Sustainability starts for us already with the product development. Our products and services also contribute to a great extent to the achievement of the climate change objectives.

From the founding phase to the present day, a sense of responsibility runs like a thread through HOPPECKE's history. 

In the interests of the environment, we focus on environmentally friendly product development, energy-efficient products and service solutions, waste avoidance and recycling, take-back and recycling. We act out of the conviction that we have to protect our planet for future generations. We are part of this society and make our contribution. In the same understanding, we are part of the UN Global Compact, the world's largest network for corporate social responsibility.



Thinking global & green

Our maxim is: "We are responsible for the careful use of the resources entrusted to us - people, capital, time, environment as well as raw materials - taking into account social aspects and promoting environmentally friendly processes, techniques and products".

Our take-back and recycling system for lead-acid batteries represents a significant contribution to the conservation of natural resources. But this is not the only way we define sustainability. For us, sustainability starts at the product development stage. Our products are specifically developed so that they can be used and recycled reliably for a long time. They should always meet the requirement to reduce energy consumption. In addition, we use environmentally friendly processes and techniques to conserve resources and the environment.

Recycling of waste lead
We have been operating our own metal smelter for over 60 years. This is a recycling plant for lead accumulators approved in accordance with BImSchG (Federal Immission Control Act) and an ultra-modern waste disposal plant certified in accordance with ISO - 9001/2000, ISO 14001, ISO 50001 and OHSAS 18001. The HOPPECKE metalworks symbolises two basic convictions of the owner family:

The careful handling of entrusted resources and the safeguarding of the company's independence. By taking back and recycling spent lead batteries, we ensure that a scarce raw material is conserved and brought into a closed economic cycle. We recycle almost 100% of the lead contained in the batteries. 

Today, we are the only European industrial battery manufacturer with a closed economic and battery recycling cycle.  Our standards exceed the legal requirements. Together with environmental authorities and environmental associations, we are constantly optimising our manufacturing techniques. 

Waste prevention
HOPPECKE's primary objective is to avoid waste of any kind. In our main plant in Brilon, waste is almost completely recycled. 

Water protection
We purify excess process water in our in-house waste water treatment plant. We strive to reduce water consumption wherever possible.

Emission protection
The HOPPECKE metal works has a modern exhaust air system equipped with a flue gas scrubber, textile dust filter system and automatic measuring system.

Energy management
Our production sites are certified according to the ISO 50001:2018 standard. Numerous measures pursue the goal of reducing gas, electricity and heating oil consumption.

Purchasing Policy


The purchasing function within the HOPPECKE Group is responsible for supporting the company worldwide through the selection, qualification and further development of the best-performing suppliers on its way to become an energy solutions provider and system supplier with a consistent brand quality at highly attractive prices. To this end, the purchasing function — in close collaboration with all stakeholders in the value-added chain— assumes worldwide strategic purchasing responsibility for all relevant goods and services, in compliance with our corporate business principles and based on ethical standards of business conduct, environmental protection and social responsibility (hereinafter "business ethics").

In accordance with its principles of ethical business conduct, HOPPECKE expects all suppliers to:

  • respect human rights and commit to observing them
  • reject any kind of forced or child labour
  • provide their workforce with a workplace that is free from hazards to life, limb and health, discrimination of any kind, violence or harassment
  • protect the right of workers to collective bargaining and recognize the core labour standards of the International Labour Organization (ILO)
  • comply with applicable environmental standards and use energy-saving processes during production as well as limit the emission of greenhouse gases
  • use natural resources carefully and take measures to minimize waste 
  • observe data privacy laws
  • comply with competition law requirements and reject any kind of corruption, and
  • observe and comply with all other statutory requirements applicable to them and applicable in their respective country.

In order to meet the procurement requirements in accordance with the principles of the HOPPECKE Group's business ethics, the individual HOPPECKE Group locations where procurement activities are carried out have corresponding purchasing guidelines and purchasing instructions in place. They define the rules, structures and processes to be adhered to when dealing with colleagues, customers, suppliers, other companies and authorities. The aim is to ensure legal and audit-proof processes and contract conclusion as well as the consistent consideration of the above-defined guidelines of business ethics. The purchasing guidelines or instructions form the basis for the preparation of additional specific instructions, checklists and procedures.

Particular attention is paid to the procurement of raw materials from regions or sources where compliance with the requirements of business ethics must be ensured through special procedures or efforts. Therefore, suppliers of so-called "conflict raw materials" for all plants worldwide are chosen exclusively by the central purchasing department of the HOPPECKE Group. Conflict raw materials, from today's perspective, are tin, tantalum, tungsten and gold from the Democratic Republic of the Congo or its neighbouring countries (Angola, Burundi, Central African Republic, Congo, Rwanda, South Sudan, Tanzania, Uganda and Zambia). The extraction of these raw materials in the above-mentioned countries is frequently associated with a violation of basic human rights and the income generated from it is used to finance armed conflicts.
It is therefore necessary that suppliers provide adequate proof of the origin of the above-mentioned raw materials to be supplied to HOPPECKE. Only suppliers who can provide adequate proof of origin may be approved for the supply of these raw materials. HOPPECKE recommends using the standardized reporting template of the Conflict-Free Sourcing Initiative (CFSI).

HOPPECKE reserves the right to assess its suppliers for compliance with the principles of the HOPPECKE Group's business ethics through audits. Such audits may be carried out by HOPPECKE, the HOPPECKE client or by a third party designated by HOPPECKE or its client.
Any breach of the HOPPECKE Group's principles of business ethics may constitute grounds for the extraordinary termination of the contractual relationship with the supplier. In the case of minor breaches, the supplier is given the opportunity to remedy the misconduct within a reasonable period of time by implementing appropriate remedial measures. In cases where the misconduct is not corrected within a reasonable period of time, as well as in the case of serious infringements, HOPPECKE reserves the right to immediately terminate the contractual relationship with the supplier and to assert possible claims for damages. 


Whistleblower and complaints system at HOPPECKE


For HOPPECKE, compliance with laws and internal regulations as well as ensuring open and trusting cooperation have highest priority. With this in mind, the whistleblower system at HOPPECKE is headed by an independent ombudsman and has been in place for several years. All employees and business partners can contact the ombudsman in confidence and, if desired, anonymously in the event of suspected violations of laws and/or contraventions of internal rules of conduct as well as in the event of other irregularities observed in their dealings with our company. In addition, the complaints procedure according to the German Supply Chain Due Diligence Act ("Lieferkettensorgfaltspflichtengesetz") is handled by the ombudsman. It offers the opportunity to point out human rights and environmental risks as well as violations of human rights-related or environmental obligations.
