Reduce, reuse, recycle

Α+ | A-

Every year, some 2 billion tons of waste - including particularly hazardous waste - are produced only in the EU Member States, and this figure is rising steadily. Stockpiling waste is not a viable solution and destroying it is unsatisfactory due to the resulting emissions and highly concentrated, polluting residues. The best solution is, as always, to prevent the production of such waste, reintroducing it into the product cycle by recycling its components where there are ecologically and economically viable methods of doing so.

Waste is an issue that affects us all. We all produce waste creating a huge impact on the environment, causing pollution and greenhouse gas emissions that contribute to climate change, as well as significant losses of materials - a particular problem for the whole world.

The amount of waste we are creating is increasing and the nature of waste itself is changing, partly due to the dramatic rise in the use of hi-tech products. This means waste now contains an increasingly complex mix of materials, including plastics, precious metals and hazardous materials that are difficult to deal with safely.

Following international standards and industry best practice, TITAN Group is fully aligned with the most recent EU waste management policies, aiming at reducing the environmental impacts of waste, achieve much higher levels of recycling and minimize the extraction of additional natural resources. Proper waste management is a key element in ensuring resource and energy efficiency, while it improves business sustainability in the long term.

One proved and well - established way to achieve reductions in energy and raw materials in the cement industry is by recycling waste and by-products of industrial processes. These materials are collectively referred to as alternative raw materials and using them means consuming fewer natural raw materials for the production of clinker. In the case of our manufacturing operations these alternative materials include:

  • blast furnace slag and iron lamination scale from iron works
  • pyrite ash from the production of sulfuric acid
  • wet fly ash and bottom ash from electric power stations
  • waste kiln refractory

In addition to the above, blast furnace slag, fly ash and industrial gypsum are also used for the production of cement reducing the quantity of clinker, natural gypsum and pozzolana required. Similarly, kiln dust removed from the circuit is used in cement production, reducing the need for its storage and disposal.

The use of alternative raw materials and fuels is also a key element in TITAN’s climate mitigation strategy. High temperatures in the cement rotary kiln enable waste management and resource preservation with the least negative impact and can lead to the utilization of waste, both industrial and municipal as fuel.
Moreover, TITAN has developed as a standard practice the reuse and recycling of concrete returns as an alternative raw material in the production of clinker and cement, saving valuable, non-renewable resources of raw material, reducing direct and indirect CO2 emissions and minimizing the need for landfilling.

Separation Technologies (ST), a subsidiary of our U.S.-based operations, is an example of our commitment to this philosophy. A member of the TITAN Group since 2002 and with facilities presently in Maryland, North Carolina, Florida, Pennsylvania and Mississippi in the U.S. (as well as in Canada and the United Kingdom), ST specializes in separating the fly ash produced as a by-product of power plants.

Rather than allowing it to contribute to already over-crowded landfills, ST separates, processes and sells it to other industrial users for the production of construction materials such as concrete and for processing to be used as fuel, thus minimizing environmental impact.

Today the company serves primarily two types of customers:

  • To power plant owners and operators, it delivers a commercially proven, flexible, least-cost, least-risk technology for processing coal fly ash.
  • To concrete industry users, ST and the ProAsh® brand deliver a consistent, high-quality fly ash that meets and exceeds customers’ needs and expectations
    for cost-savings, dependability, product strength and durability, and customer desirability as an environmentally friendly, “green” product. ProAsh can also contribute to acquiring LEED points from the Leadership in Energy and Environmental Design (LEED) Green Building Rating System, a nationally accepted benchmark for the design, construction, and operation of high performance green buildings in the U.S.

ST’s activity is important because it demonstrates that environmental awareness and protection is not only compatible with corporate commitments to shareholders and other stakeholders, but can also create entirely new business-models and opportunities for revenue generation.
