Heinrich Feess GmbH received the coveted Deutscher Umweltpreis environmental award from the German Federal Environmental Foundation . Managing director Walter Feess received the award on behalf of the company , which recycles concrete , asphalt , and building rubble . In collaboration with CDE Global , Heinrich Feess GmbH developed an innovative recycling model for construction , demolition , and excavation waste . Before the CDE processing plant was installed at Kirchhiem , around 10 % of demolition waste collected on site was unrecyclable , being a mixture of demolition and excavation waste ( from building foundations ). Now , waste material is being processed successfully , reducing waste and increasing volumes of recycled sand and aggregates for reuse .

Maintenance means mileage at Chinese quarry
China ’ s Li Yu Shan Mining quarrying company produces small- and medium-sized aggregate of 20 – 25mm and 50 – 60mm . A third of its output is used as base material for the thousands of kilometres of China ’ s high-speed railway tracks .
Li Yu Shan Mining has built a solid reputation in China as a quarrying specialist , producing 1.5 million tonnes of material in 2015 .
Since 2010 , Li Yu Shan Mining has purchased seven EC210B and two EC240B excavators from its local Volvo CE dealer , Zhejiang Liyang Machinery . The EC210B and EC240B excavators are equipped with a highstrength boom and arm , allowing excavating depths of up to 6m . To maintain stability on the rocky terrain , the machines also feature robust X-shaped frames made of high tensile steel , to ensure a long service life .
Yuan Jian Zhong was impressed by the good fuel economy offered by the Volvo B-series excavators . “ Volvo excavators typically consume 14 – 15 litres per hour , which , when compared to competitor models that often average 19 litres , translates into significant financial savings ,” he explains .
Greater savings have allowed Li Yu Shan Mining to expand both its operations and fleet , and the company recently put down a USD450 000 deposit for the first three of a batch of 15 Volvo EC380D excavators for work on an upcoming mining project .
With over 15 years ’ experience of owning and operating quarry equipment , Yuan is satisfied with his decision to choose Volvo . “ I switched to Volvo on the advice of friends and colleagues who highlighted Volvo ’ s better performance and after-sales service ,” he adds .
Because of the relative slowdown and consequent lower equipment utilisation rates , contractors are keeping machines for longer , which requires them to take special care of their machines .
Zhejiang Liyang Machinery manages the maintenance of more than 1 000 machines in Zhejiang alone , using Volvo ’ s remote telematics , CareTrack , to alert customers of impending maintenance deadlines . “ The technology enables Volvo CE dealers to help customers extract an extra USD30 000 out of the lifetime of a machine , even in the harsh conditions of a quarry ,” says Cliff Zou , regional service manager at Volvo CE China .
