Sustainability

Sustainability day by day

In our daily processes and procedures, we have been endeavouring for years to reduce waste and to procure and use goods and operating materials in a resource-saving and sustainable manner. Where technically possible, we are constantly replacing consumables and packaging materials with environmentally friendly alternatives. Constant dialogue with suppliers, partners and customers on the subject of sustainability is part of our daily work and in line with our ecological responsibility.

Our merchandise means that we are very positive about sustainability per se: 
Preserving, fermenting, homemade products and baking in jars reduce packaging waste and lower global transport costs.
Jars and bottles are durable and reusable. If damaged, they can be simply and easily recycled.
The same applies to metal packaging, which has the highest recycling rate in Germany.
Commercially used plastic packaging is returned to the recycling cycle (keyword: Packaging Act). In addition, many of our suppliers already offer packaging made from reclaimed or recycled materials as well as ‘ocean plastic’. Plastics are now more than 95% recyclable, in contrast to the new paper composites, which are less than 90% recyclable and therefore increase the amount of waste by a good ⅓! (Dr Karras, materials scientist, expert in eco-design).

We supplement well-known ‘everyday items’ such as 100% recyclable WECK preserving jars (with a recycled glass content of 40%) with stainless steel handles, for example, to turn them into sustainable cups and cocktail glasses, or by adding wooden lids to turn the jars into attractive storage containers for use at home or for ‘unpackaged shopping’. This is also an active contribution to reducing disposable items and putting sustainable awareness into practice with concrete products.

Examples for already implemented internal optimisations

  • Continuous reduction in paper consumption with general use of FSC-certified paper
  • Use of water dispensers to use fewer disposable and returnable bottles
  • Waste reduction through secondary/third party use of supplied packaging material, e.g. to secure loads, as filling material, etc.
  • Use of night-time electricity to charge electric industrial trucks
  • Switching from multilayer material to composite-free goods (e.g. wrapping film)
  • Separate disposal circuits/recycling for sheet metal (10 tonnes), glass (14 tonnes), plastic, cardboard (58 tonnes) and film (13 tonnes) p.a.
  • Printer cartridges etc. as exchange/return goods (recycling system)
  • Lighting control via motion detectors and use of LED lamps

Good recycling quota for metal packaging

The raw material (tinplate = tinned sheet steel) of metal packaging is sustainable and often recyclable. Most metal packaging can be recycled as a secondary raw material to make something new out of metal - without any loss of quality, i.e. without downcycling. Metal packaging has the highest recycling rates of all packaging materials. Packaging steel is recycled up to 85.5% in Europe (APEA Press release 8th June 2022).

Sustainable glass

Glass is the oldest packaging known to mankind and has constantly evolved in line with modern requirements. 
In terms of both economic and ecological aspects.

Conservation of resources during production

  • Use of predominantly natural raw materials in glass production (available in large natural deposits; largely biodegradable in Germany).
  • Increasing energy efficiency in glass production through economical melting technology, by reducing the weight of glass as packaging and by utilising used glass (60%).
  • Today's lightweight glass products consume less raw materials and energy in the manufacturing process while maintaining the same stability.


Recycling after use

  • Glass is 100% recyclable without downcycling (loss of material) and therefore has a closed material cycle.

Characteristics of glass as packaging

  • Glass is inert - there is no interaction between the material and the contents, the flavour of the food remains untouched.
  • Glass is ideal for preserving food and therefore helps to reduce food waste.

Facts about plastics

Recyclability
Today, almost 100% of household packaging is recycled in Germany. Of this, 56% is recycled and reprocessed as secondary raw materials. According to the Federal Environment Agency (UBA), the recycling rate for plastic packaging waste was 48.4% in 2021 (an improvement of 3.8% compared to the previous year).

Material efficiency
Today's plastic packaging is characterised by its very low weight. At the same time, their performance has been increased. By 2025, a 90% share of recycled plastic (e.g. PCR) is specified for the production of plastics in Germany.

Product protection
Optimised plastic packaging reduces food waste in the retail sector by better protecting food. Plastic packaging also reduces losses during transport and storage in the non-food sector, thus saving valuable environmental resources. The aim is to maximise protection with as little packaging as possible.

Consumer protection
Plastic packaging protects its contents from spoilage and damage. They ensure quality, shelf life and hygiene. Conversely, UN hazardous goods packaging can protect the environment from toxic or highly flammable contents. Tamper-evident seals on plastic packaging serve to protect against theft and counterfeiting.

Microplastics / macroplastics
According to a study by the Fraunhofer Institute for Environmental Technology in Oberhausen, 446,000 tonnes of plastic emissions are produced every year. These consist of 26% macroplastics (larger plastic parts, such as plastic bags or other larger plastic waste) and 74% microplastics.

Causes/sources of microplastics

  • Abrasion from car tyres, bitumen in asphalt, road markings, plastic packaging, shoe soles
  • Pellet losses
  • Blowing from sports fields and playgrounds
  • Release on construction sites
  • Fibre abrasion during textile washing
