The WASTEred project aims to promote the use and encourage the market penetration of LODOred, a new and ECO-Innovative product, in the food industry (slaughterhouses, meat processing and dairy companies) in order to reduce the large amounts of sewage sludge generated in their wastewater treatment plants. The expected reduction will decrease the environmental impact of these sectors, as well as the costs associated to the sludge management.

WASTEred Objectives


Since the WASTEred project is aimed to launch the ECO-Innovative product LODOred into the European Market, specifically in the meat and dairy industries, two lines of objectives have been defined: environmental and economic ones.


The environmental objectives are listed below:


Objective 1: Waste reducing in the targeted food industry sectors, reducing at least 35 % surplus sludge in the three pilot plants in order to demonstrate the applicability in the meat & dairy industry within the project duration, and covering 20 % of the target meat and dairy industry within the EU in the next 7 years after the project duration.


Objective 2: Improving water quality of receiving water bodies (lakes and rivers) through better treatment performance in the WWTPs, reducing pollution (eutrophication) on surface, enhancing water quality of effluents with at least 20 % less BOD/COD and 20 % less phosphates and nitrogen (esp. nitrates), by improving treatment performance in the three selected wastewater treatment plants through higher efficiency in the biological treatment step, during the project execution, and introducing LODOred to other potential clients (ca. 2.600 plants) leading to 20 % less phosphates and nitrogen pollution from these industries to open water bodies in Europe, after the project finishes.


Objective 3: Reducing the “ecological footprint” of the complete wastewater treatment process in the food industry: a reduction of 35 % in the production of sewage sludge in the three case studies and in ¼ of the potential market after the project duration could lead to the following results:





To reduce transport of sludge for disposal (km truck transport)

7,500 km

6.5 million km/year

To reduce polymer consumption for sludge dewatering (ton)

4 ton

6,500 ton/year

To reduce energy consumption for sludge handling, dewatering, drying and burning (%)

25 % less

25 % less

To reduce air pollution pollution through savings in transport (CO2) and burned sewage sludge (nitrogen oxides) (ton)

1,500 ton less

1.4 Mio ton/year


Objective 4: Facilitating access of SMEs to innovative "green" knowledge, increasing awareness and promoting nerworking, what will improve not only the competitiveness of these companies but the general access to new and innovative technologies and products too.


Besides all positive environmental effects, without giving a clear economic benefit to the potential users of LODOred, the targeted market share cannot be reached. The following economic objectives and markets will be targeted.


Objective 1: Reducing disposal costs for sewage sludge (35%), since the implementation of the Directive 91/271/EEC concerning urban waste-water treatment has generated an increasing volume of sludge all over Europe and less disposal routes are available. Based on its composition and its hygienic risks, most of the sludge generated from wastewater coming from the meat and dairy industry goes to incineration, whose costs per ton of sludge treated vary strongly in Europe, between 35 €/t dewatered sludge in Poland and 120 €/t dewatered sludge in Switzerland. For an average meat/dairy company (3,500 t/year) sludge disposal costs vary between 120,000 and 420,000 € per year. Taking into account the fast rising costs for sludge disposal, energy and transport in Europe and limited sludge incineration capacity these costs are most likely to rise even more in the next years. Applying LODOred would reduce the sludge disposal costs by at least one third for each client.


Objective 2: Reducing costs for polymers for sludge dewatering (50%), since these costs vary between 3-5 €/kg and an amount between 7-10 kg are needed to dewater 1 t of surplus sludge (average costs between 73,000 – 175,000 €/year/client), therefore a total saving of 50-55% of polymers could be achieved.


Objective 3: Reducing energy costs (25 % energy reduction), which is used in the handling, storing, transporting and incinerating of sludge. It is connected to high energy costs for pumping, dewatering, transporting, drying and burning. Taking into account the reduced transport, running time of centrifuges and presses and the energy needed for sludge drying a total energy saving of 25 % in each of the case studies and later for each client is foreseen.


Objective 4: Reducing pollution fees 20 % (pollution charge for quality of effluents), since many European countries, the producers of wastewater pay a specific pollution charge related to the water quality of their effluents. A 20 % better effluent quality (BOD/COD, phosphate and nitrogen content) of the treated wastewater is targeted and will lead to reduced pollution fees for the industry.
