Comprehensive waste, water, and energy solutions

Preseco’s approach to solving the water, waste, and energy challenges faced by its customers is based on comprehensive solutions and innovative state-of-the-art technology – designed to help customers enhance their competitive advantage by turning waste streams into added value.

Waste, water, and energy have been seen traditionally as separate sectors, both from a business and a technological standpoint. Preseco sees this as a wasted opportunity.

By overcoming conventional boundaries and integrating waste, water, and energy technologies under one roof, Preseco believes it can generate significant economic and environmental added value for the customer.

This is particularly highlighted in a new-generation solution that the company has developed for slaughterhouses. Combining biogas, composting, and wastewater treatment units, this enables all the waste and wastewater from a slaughterhouse to be treated on site in one integrated plant.

The solution is compact and generates energy for the slaughterhouse and any residential areas nearby, while reducing the costs normally associated with waste transportation and service outsourcing.

Preseco received the INNOFINLAND award in December 2008 for a turnkey integrated waste treatment solution designed for slaughterhouse use.

Waste to energy

Biowaste from households and kitchens, food processing residues, slaughterhouse waste, by-products from fruit and grain processing and distilleries, liquid and solid manure, and wastewater treatment sludge can all be used as inputs for Preseco’s processes – turning waste into energy, compost soil, and/or clean water. Municipal solid waste (MSW) can be easily separated into energy and other fractions.

The company’s industrial biogas plants are based on patented Anaerobic Digestion Accelerator (ADA) technology, and perform particularly well with energy-rich biowaste, such as fats and animal proteins. A customised version can produce biogas for heating or generating electricity, or refining into vehicle fuel.

For composting purposes, Preseco offers its patented Accelerated Composting Unit (ACU) technology. This continuous, drum composting process requires no chemicals, additives, or additional energy input, and generates zero runoff and emissions. The ACU process can be easily combined with other Preseco technologies, such as biogas, water treatment, and biodiesel plants to create integrated solutions.

Whatever the configuration, all solutions are designed to match customers’ needs and waste volumes. Drawing on the project know-how of its ISO 9001-certified organisation and strong network of partners, Preseco acts as a process integrator, handling customised planning and design, construction, and operation of completed plants for customers.
