Quarries are evolving
Quarries are buzzing with round-the-clock extraction operations which feed granite and aggregates into the construction and infrastructure industries. When versatile giant equipment operates with high productivity targets and tight deadlines, emission control in mines and quarries becomes a critical focus.
The EU and international emission regulations aim to create a low carbon and energy-efficient economy with goals to reduce greenhouse gases by 20%; reduce energy consumption by 20%, and meet 20% of EUs energy needs from renewable sources by 2030.
The face of mining and quarrying is changing with a keen focus on contributing towards reduced energy consumption and higher energy efficiency.
The changing role of construction equipment in quarries
From lighting to pumping to power generation, sustainable equipment profiles are becoming an integral part of the quarry portfolio. Here are a few key ingredients in the sustainability strategy for quarries.
Fuel efficiency
With Stage V and Euro 6 diesel engine regulations, advanced fuel-efficient engines are the need of the hour. Forward-thinking construction equipment manufacturers are gearing up to get their machines equipped with the latest technology engines while demonstrating their commitment to a better environmental footprint.
Electric models
With stricter emission regulations, the transition from diesel to low-diesel consumption equipment to electric models is gaining momentum. Not just electric cars, but also heavy equipment manufacturers are rolling out electric versions of their earlier diesel-driven models to meet their sustainability goals. Hence the push towards electrification in quarries is an important development which can be supported with standalone or hybrid options to cover unpredictable power loads.

Digitalization in quarries
In the quest to achieve sustainability goals, safe operations in quarries remain a priority while bringing in energy-efficient operations. Digitally connected intelligent machines dot the quarry landscape and reduce downtime while increasing efficiency in quarry operations.
Atlas Copco will be launching new intelligent controllers which will optimize energy generation, distribution and consumption through advanced data management to improve machine performance and efficiency.
Pumping solutions

Quarries are prone to flooding, as is the case for abandoned quarries or underground quarries when they are dug below the water table. Managing the water that is accumulated from heavy rainfall and groundwater seepage in quarries is a crucial task which must be done effectively in order to protect construction equipment and allow for operations to continue. The advanced pump portfolio from Atlas Copco offers electric submersible pumps under the WEDA pump umbrella, which has innovative features including a high performance-to-weight ratio, hardened high-chrome impellers and

The advanced pump portfolio from Atlas Copco offers electric submersible pumps under the WEDA pump umbrella, which has innovative features including a high performance-to-weight ratio, hardened high-chrome impellers and Wear Deflector Technology, which is designed to minimise wear, ensuring durability for a longer working life. By meticulously redesigning the pump range with the latest 3D modelling techniques, the pump’s efficiency can be increased while lowering unplanned downtime issues in tough working environments like quarries. Quarry owners will less often find themselves forced to replace pumps as service life and repairability are built in from the ground up. The future of pumps will be increasingly sustainable as electrical pumps will further reduce emissions when powered with fossil-free electricity.

In addition, Atlas Copco has recently launched a range of fully electric self-priming dewatering pumps. The E-Pump range, which comprises the E PAS and PAC electric models, offers an exciting electric, no CO2 emission alternative to diesel-powered surface dewatering pumps during pumping operations. This allows customers to reduce their emission footprint and operate no fuel consumption. They are ideal for a wide variey of applications, like sewage bypass, in the municipality sector, construction sites and quarries.
Our E-Pump range is quick and easy to install, making it a Plug and Pump solution. Both the E PAS and PAC electric models have a tremendous impact on the overall productivity of the units, lowering the total cost of ownership compared to their diesel counterparts and ensuring high performance for longer periods of time.
Energy Storage Systems
Atlas Copco's ZBC energy storage system
As the use of energy storage systems becomes more popular, new sustainable innovations will continue to bring more energy efficiency in quarries as well. Atlas Copco’s technologically superior Li-ion battery energy storage systems, when paired with its low fuel-consuming generators, redefine hybrid technology for smart load management resulting in reduced emissions, better operational efficiency, lower total cost of ownership and higher ROI.
When operating standalone in Island mode, with zero emissions and zero noise, these modular energy storage systems operate as a primary source of power and accelerate the journey towards clean energy with practically no maintenance.
Design innovation
With skilled design engineers and expertise in both generator and pump product development, a combined green solution engineered to dramatically reduce fuel consumption and CO2 emissions is an expected outcome. New emerging technologies like submersible pumps operating with medium-sized battery packs will transform the hybrid canvas and further reduce the total cost of ownership in quarry operations.

With renewable energy generation gaining momentum, solar power has made its way into Atlas Copco light towers and battery pack development. The HiLight S2+ solar-powered light tower taps into solar energy to reduce CO2 emissions by up to 6 tonnes as compared with other technologies. This is a great asset in quarries for night extraction operations where bright and safe light enable operations to continue for 11 hours at a stretch. By reducing electricity costs in quarries with solar energy options, compliance with CO2 emissions and noise regulations allows work in quarries to carry on autonomous operations all year round when the solar power is adequately tapped.
HVO – biodiesel hydrotreated vegetable oil is a next-generation fuel that further nurtures sustainability goals into construction equipment DNA, reducing the carbon footprint of the machines. This renewable fuel offers a 90% CO2 emission reduction compared to diesel and lasts longer in the tank, which in turn reduces the risk of water ingress, microbial growth, and overall risk of contamination to equipment, making power and pumping operations cleaner and greener.
For Atlas Copco, a quarry is not just a pit in the ground. It is a highly productive worksite which plays a crucial role in core infrastructure development such as roads, metros, expressways, airports, and highway expansion with its aggregate output. As quarries aim to complete the production cycle with as low as possible carbon footprint and with high productivity outcomes, Atlas Copco will focus on continuous innovations in engines, fuel, renewable energy, product design and other ways to calibrate a better balance between energy production and consumption.
With the ever-evolving new clean energy technologies from Atlas Copco’s generators, energy stoage systems, pumps and light towers, the journey towards more sustainable quarries is more well-defined and achievable.
Atlas Copco is committed to contributing to low carbon emissions with state-of-the-art advanced equipment serving various worksites, including quarries.
