Waste as a raw material

EVVA sees waste as a raw material that must be used as sparingly as possible. As of 2020:

  • EVVA finished products are made from 68.8% used materials,
  • 26.5% is recyclable waste (swarf, solid waste, etc.), which EVVA also reuses 100%! That is why we refer to "recyclables', not to "waste',
  • 3.46% is non-hazardous waste such as plastics or wood
  • and 1.24% is hazardous waste such as oil, electronic waste, galvanic waste or batteries.
  • The input/output analyses under Recycling & Resources Overview contains comprehensive data on waste

Potential and measures for less waste:

Despite the measures, our waste volume has only decreased slightly in recent years: From 0.55 kg per kg of product in 2015 to 0.54 kg in 2019 and also in 2020. The reason for this is that EVVA is producing more and has increased output by 14.5% between 2015 and 2019, by 12% between 2015 and 2020 (2020 reduction due to pandemic). However, the following measures could and can keep the amount of waste at a constant level:


Paper

By increasingly shifting to digital processes (e.g. for construction drawings, order documents, etc.), EVVA has been able to save around 9 tonnes of paper since 2015. However, the paper waste at the headquarters has declined from 6 tonnes in 2019 to 5.5 tonnes in 2020. EVVA would like to further reduce its paper requirements – see targets below. Paper consumption will be reduced in the next few years due to the gradual transformation to paperless production. From order entry to production to goods delivery, many processes are to be digitised. More on this under Digitalisation.

Banish plastic/paper cups: In 2019, all plastic cups from the 8 coffee machines at the headquarters were banned and initially replaced with paper cups. Here, too, EVVA once again pressed ahead. In 2019/2020, employees were asked on the intranet and via stickers affixed directly to the vending machines to always use their own coffee cups instead of paper cups. To promote this action, all employees received an EVVA-branded cup as a gift, which they could then personalise. The campaign was a great success. With around 15,000 portions of coffee consumed every month, the savings are impressive:

Environmentally friendly thermal paper
In 2021, EVVA switched its till paper for issuing goods and internal logistics to a blue thermal paper (Blue4est), which has won several environmental awards. It is produced without bisphenol A, can be disposed of with the waste paper (the previous white paper only with the residual waste), does not fade and is also cheaper.
 

Bulk waste, residual waste

From 2019 to 2020, the proportion of bulky waste in the headquarters was reduced by around 1 ton to a total of 6 tonnes. In 2020 also numerous old machines, tools and furniture were finally disposed of as part of lean management measures. The proportion of residual waste has remained roughly the same since 2010 and is around 30 tonnes.


Input/output keys

In 2013, an input of 185,388 kg of key blanks was balanced by an output of 145,132 kg of finished keys. EVVA was able to significantly improve this ratio in the last few years and thus avoid a lot of scrap and waste. We have achieved this through more efficient and accurate production processes as well as lean management tools (value stream mapping, Kanban, etc.) that target wasting.

This positive development continued in 2020: 158,323 kg of input (including: key blanks 151,313 kg and finishes such as magnetic pills 110 kg and plastics for keys of around 6,900 kg) faced 152,235 kg of output. The total numbers have decreased in 2020 due to the pandemic

 

Hazardous waste

such as oil or electronic waste. These materials are required for electroplating and for production. They are disposed of professionally by specialist companies in accordance with legal requirements. No leakage of harmful substances has occurred. Electronic waste has increased from 1 tonne in 2013 to 5.4 tonnes in 2020. This is amongst others related to the replacement and disposal of old lighting fixtures, (see LED changeover). Also old monitors, electronic machine components and cables were replaced. Another reason is also the increased demand and production of electronic and mechatronic security systems. The battery requirement has therefore increased from 42 kg in 2010 to 89 kg in 2020. The further changeover to oil-free Clean Production machines will continuously reduce EVVA’s oil requirements.


Plastics

Our plastic output (e.g. for thumbturn covers for electronic access systems) has increased due to the greater demand for electronic products – from 174 kg in 2010 to over 1,523 kg in 2013 to 2,477 kg in 2019. In 2020, the value fell to 2,266 kg due to more efficient packaging processes.


New electroplating processes

From 2020, EVVA has partially converted electroplating processes (for the surface treatment of our mechanical safety products) at the headquarters from powder to liquid. This simplifies the automated feeding of substances and thus an efficient and quantity-reduced supply.


Lifetime

Products and components such as batteries with a longer useful life also generate less waste and sets an example against the throwaway society. For more information, see Quality and Permanent Innovation.

Our targets

Fulfilment date: 2024

How: EVVA will be pushing ahead with paperless production and digital order processing in the coming years.

  • An example from internal order processing: Only one delivery note form per order will be necessary instead of the previous 3 delivery note copies. The data flow for shipping is provided digitally, thus savings of around 100,000 sheets of paper could already be achieved in 2021
  • Another example from order processing involving partners/customers: The new digital EVVA ordering platform for trade partners will further reduce the need for paper. As of 2021, already 6,000 less sheets of paper were required

Positive effects: The current paper requirement at EVVA headquarters is 43 tonnes per year. The planned reduction to 30 tonnes results in a saving of around 30% per year.

Fulfilment date: 2022

How: EVVA has been transforming electroplating processes in production since 2020. This will allow a more efficient introduction of substances.

Positive effects: The chemical consumption should thus decrease from 7,784 kg in 2019 to 6,600 kg in 2022. This would mean approximately 15% reduction in the amount of waste to be disposed of.
