At the beginning when our first forge started, this term did not exist as it was self-evident to act and operate sustainably. Today sustainability is more important than ever. In recent years, LEMKEN has made a considerable contribution to ensuring that this attitude is once again taken for granted. For efficient Ecos!

Sky blue sustainable and economical

Factories are either environmentally friendly or profitable. LEMKEN disproves this prejudice, because machines are manufactured in the Lower Rhine region in an energy-efficient, sustainable and cost-conscious manner.

2004 – The journey begins

Viktor Lemken commissions his daughter Nicola to build a new office building. Nicola Lemken takes unusual paths for this and visits the pioneers in this field. A low-energy building with offices, reception and exhibition and training halls will be constructed, which will be completely heated and cooled by the waste heat from the neighbouring forge. The consumption costs of the “low-energy building” are approx. 77 % lower than the costs of conventional office buildings.

2009 – A push forwards

An energy network system and the construction of a new painting plant are being launched, the core of which is formed by so-called energy rings that recover and reuse energy at various points in the plant via heat exchangers. In addition, the waste heat can be used for the underfloor heating of the adjacent production halls and a social building. If too much energy is generated than is needed, it is stored in underground storage facilities where it can be used, for example to power up the painting plant. As a result, central energy circuits and storage facilities ensure significantly lower consumption of conventional energy sources such as gas and water. The annual savings amount to approximately 500 tons of CO₂ .

2012 – As big as a football field

This is the size of the photovoltaic system with over 2000 solar modules and more than eleven kilometres of cabling on two of the hall roofs. The installed total output of 500 kilowatts is fed into the public grid and is sufficient to supply around 100 four-person households. In addition, the LEMKEN photovoltaic system saves 250 tons of CO₂ per year . Further systems on the remaining hall roofs are being planned.

2015 – Another energy duo

Because LEMKEN likes its role as an energy producer and saver so much, the construction of two combined heat and power plants with a refrigerating machine and district heating network has now started. With an overall efficiency of 87 percent, the plant with its meter-high chimneys runs almost loss-free. The CHP duo and the refrigeration system generate a thermal and electrical output of 1800 kilowatts, providing the halls with heat in the winter and cool air in summer.

2018/19 – A machine grey beauty

The latest project is a fully automated hardening and bending plant operated by two robots. It can process up to one ton of steel per hour and produce the familiar DuraMaxx wear parts, for example. Hardening is one of the core competences of a plough manufacturer and tempering the special steel purchased is LEMKEN’s best-kept secret. In contrast to conventional furnaces, the furnace technology, which is insulated with ceramic fibres, can be shut down at the weekend to save energy. The required cooling capacity for the entire plant is provided by the company’s own CHPs. In this way, up to 728 tons CO₂ can be saved.

2019 -A blue and white flag is waving

The climate protection flag has been flying at the reception building since spring 2019. LEMKEN received the award from the Climate Alliance of the municipalities of the Wesel district for its commitment to energy efficiency and climate protection. LEMKEN will continue to develop its processes and technology continuously and efficiently in the future, because Nicola Lemken wants to remain a few steps ahead of the legislation.

Factories can be both environmentally friendly and profitable.
In addition to ecological and economic considerations, LEMKEN is also fully aware of its social responsibility.

Saving energy with plough and cultivator

Once the machine and work result have been determined by the farmer, there are various ways of saving fuel without having to sacrifice work quality with the LEMKEN pull point adjustment with OptiQuick on mounted reversible ploughs and OptiLine on semi-mounted ploughs. By adjusting the pull point to an optimum range, diesel consumption can be reduced by nine percent. Positive side effect: driving without side draughts reduces wear on the ploughing equipment and relieves the driver.

Without changing the quality of work, traction boosters also offer elegant saving opportunities. At LEMKEN, these are also installed on diamond ploughs and carat cultivators with Contour Track. This relieves the load on the front axle and applies pressure to the rear axle of the tractor. Tyre slip is reduced and energy is saved.

Incorrectly used cultivator coulters unnecessarily increase diesel consumption. From around 15 centimetres upwards, wing shares are often ineffective. However, each change of coulter means time consuming. With the LEMKEN quick-change system the coulters can be changed within a short time without tools. In this way, the cultivator can quickly be equipped with the right tool every time – for shallow cultivation with wing shares and for deep cultivation with a narrow share. You save time and energy!

The new E-Mobile

Due to the approaching change in mobility and ever more everyday products of the manufacturers, but also as “The Agrovision Company”, we have decided to jump on the bandwagon and expand our fleet with a modern electric car.

A drive in the BMW i3 is a silent pleasure, which is accompanied by a good portion of go-kart feeling thanks to the direct steering, 170 hp and direct full torque. The kinetic energy recovery during braking additionally charges the battery while driving.

Conservation of resources & biodiversity

“Our vision is to develop and improve machines and processes that provide healthy food and energy for the ever growing world population.

Digitalisation, cobotics and sustainability of the processes for the purpose of conserving resources and ensuring biodiversity represent a completely new challenge”.”

Prof. Dr.-Ing.Thomas Herlitzius Director of the Institute for Natural Product Technology at TU Dresden

Into the future with GPS

LEMKEN has been following this path for some time.
And the Swiss Urs Niggli, former director of the Swiss Federal Office for Agriculture, is also convinced that traditional knowledge must be combined with high-tech.
While monocultures such as wheat and rapeseed are still being planted today, in the future several crops will grow on the same field: trees, shrubs, vegetables.

On the one hand, this brings biodiversity back to the fields. And on the other hand it is good for the harvest.
The 66-year-old Niggli predicts up to 150 percent more yield. “All this is made possible by technology: GPS-controlled tractors can drive around bushes and trees. In the harvester, sensors look to see that the wheat grain is scooped to the left and the pea grain to the right. The geometry of the field will also change. Today we have square fields. In the future we’ll grow crops in strips along contour lines.”
