When buildings are demolished, a lot of rubble is produced that is recycled to save resources. (© CL-Medien/Shutterstock.com).

From demolition to house: sustainable recycling of construction rubble


Recycling of building materials is becoming increasingly important in times of increasing sustainability. When buildings are demolished, recyclable rubble accumulates. This is crushed, sieved, sorted and processed. Recycled rock can then be reused as a building material. And even the construction machinery used can contribute to a circular economy, as buying and selling used machinery gives i

Quiet humming instead of loud hammering: Electric mobility on construction sites

Construction sites are one of the largest sources of carbon dioxide emissions. The machines used in construction also contribute to these “gray emissions”. Many companies are currently switching to electromobility to improve their carbon footprint. Selling their old diesel machines can make it easier to invest in this new drive technology.
The construction industry accounts for almost 8% of g

Portal milling machines have large dimensions and are therefore expensive to buy. But they are available cheaper on the second-hand machine market. (© Surplex).

Big, bigger, portal milling machines


54 m long, 14 m wide and 12 m high – these are the workspace dimensions of the largest portal milling machine in the world. But how are such giant milling machines used? What advantages do portal milling machines offer? And how can the high investment costs be reduced?
To be able to process large workpieces, you need large machines. With a clearance height of 12 m and a width of 14 m as we

Cleanliness and quality assurance take priority when packing tablets. This is also possible with used production systems. (© Cergios/Shutterstock.com).

How do tablets actually end up inside their blister packs?

41.1 million packages of Ibuprofen were sold in Germany alone in 2020. While they’re something we often have close at hand, very few people know how the individual tablets actually end up inside their blister packs. Speed, safety and affordability are a must when it comes to production. This is where used blister machines can come in.
A blister pack is a display packaging that allows the custom

Balancing between optimism and caution

The opportunities and challenges the metalworking industry is facing in 2023
In recent weeks, many companies have been looking to the new year of 2023 with mixed feelings. The coronavirus pandemic, which dominated the past two starts to the year and caused major restrictions, has faded in significance. Even China, which had, until recently, operated the strictest “no covid” strategy, has began

Fully automatic production lines are already standard in automotive engineering. Suppliers now need to catch up. After all, the drive transition will require maximum flexibility. (© Jenson/Shutterstock.com).

Suppliers: Achieving the drive transition with used industrial robots

Switching to electromobility is among the greatest challenges facing automotive suppliers. They currently lack certainty about investments, which are nevertheless necessary. Used automation systems can be purchased in order to minimise expenditure during the transitional phase from conventional to alternative drive systems.
Still a long way to go for climate-neutral vehicles
It will take qui

The EU economy in 2022: Rising energy prices and inflation rate. However, the used machinery market is not so dependent on this. (© Leonid Sorokin / Shutterstock.com).

2022 in retrospect: the used machinery market remains stable

2022 is over. But its impact is far from over: the outbreak of war has further exacerbated the industry's insecurity and already existing problems have been compounded. Despite all the uncertainty, business has been good for some industries, such as the used machinery market: it can benefit from supply chain problems and threatening inflation.

Insulating the outer walls increases a building’s energy efficiency. Energy-based renovations to existing buildings form a key part of a climate-neutral Europe. (© Canetti / Shutterstock.com).

No building renovations, no energy transformation

As an old proverb puts it: “Anyone who has money and buys an old house and renovates it is a fool.” But is that really the case? From an ecological standpoint, renovating houses instead of tearing them down and building them anew makes sense. Many construction measures aimed at boosting energy efficiency are promoted and are technically advanced. But the ancillary building trade is suffering from

Energy crisis in Europe: a balancing act for the industry

The EU’s pioneering role in climate protection matters is not without its disadvantages, with its energy supply hugely dependent on gas. The Ukraine War has resulted in sharply rising gas and electricity prices and while a way out of the crisis is currently being discussed on the political stage, things remain unclear for the industry. A wave of insolvencies currently looms, triggered by rising co
