Project description:

Background

Waste generation is a serious social and environmental problem for modern economies. Inappropriate waste management can impact on the climate, ecosystems and human health. However, when waste is correctly managed it can become a resource, helping to conserve natural resources and contribute to sustainable development objectives. In Spain, a high proportion of waste is still disposed of in landfill. However, the national plan for waste 2007-15 encourages new practices based on selective collection, recycling, and stabilisation and recovery of non-useful fractions.


Objectives

The DEMONSTRATION OF KDV TECH project aimed to develop the first full-scale demonstration of catalytic depolymerisation technology for the processing of municipal solid waste (MSW) produced in a Catalonian district of 177 000 inhabitants. This demonstration plant, designed to treat up to 30 000 tonnes of mixed MSW per year, used catalytic depolymerisation technology to convert mixed biodegradable MSW (i.e. the non-recyclable fraction) into a synthetic diesel, which can replace conventional diesel. Specific objectives included technical and feasibility studies of the new waste recovery technology, and the repositioning of the beneficiary company as a ‘neutral carbon emissions’ enterprise.


Results

The DEMONSTRATION OF KDV TECH project developed the first pilot plant with demonstrative capacity based on innovative DieselR technology. The DieselR process utilises a catalyst to break down long carbon chains (polymers) into shorter carbon chains that comprise a high-quality diesel fuel. The process represents a clean, quick and efficient treatment for biodegradable non-recyclable waste fractions of urban origin. The facility in Constantí has the capability of reducing the amount of urban waste sent to landfill by 40 000 tonnes/year and producing 15 000 tonnes tons/year of diesel fuel, which implies an annual reduction of 44 000 tonnestons of CO2 emissions. The beneficiary successfully modified the available catalytic depolymerisation technology for the treatment of solid waste, in a way that overcomes the technical limitations of other solutions implemented to date. Built to be consistent with the guidelines of the Waste Framework Directive (2008/98/EC) and Directive 1999/31/EC, which requires Member States to reduce the amount of waste sent to landfill, the pilot facility has sufficient capacity to treat around 30 000 tonnes of mixed non-recyclable waste, equivalent to that generated by 180 000 inhabitants in an urban area.

GRIÑO ECOLOGIC, S.A., the sole beneficiary, originally designed a progressive strategy in three stages to achieve the necessary modifications to an existing pilot plant. The first stage involved the fitting out of the existing plant to operate in continuous conditions, with a treatment capacity of 200 l/h. The beneficiary designed, as a second stage, a technological improvement plan to increase the treatment capacity to 900 l/h, while a third stage would see a second catalytic treatment unit added to bring the total treatment capacity to 1 800 l/h. The operating tests were started in September 2012 using mineral oil, with a capacity of more than 200 l/h being achieved. However, due to problems with pipe blockages, the subsequent technological changes were made gradually so that they could be closely monitored and modified whenever necessary. By October 2013, modifications were made to increase performance to the maximum 1 800 l/h. With the current production capacity of the pilot plant and the operating levels achieved, a production of over 11 000 cubic metres of synthetic diesel fuel can be expected per year.

During the modification stage, the beneficiary optimised the process by identifying the most suitable fluidisation liquids to be used, such as mineral oil or dried MARPOL residues, and by finding that the best results were obtained used by using a mixture of crushed solid waste with a 25-40% of Solid Recovered Fuel (SRF) enriched with low density polyethylene. Several adjustments in the heat exchanger were carried out to stabilise the process and these have improved its performance. In addition, the beneficiary reduced the coking time and prolonged the running time in continuous conditions. The inerts treatment module currently operates under continuous conditions for no more than 14 days in a row, so further redesigning is necessary to allow the plant to work continuously for longer periods.

Finally, aside from reducing 40 000 tonnes/year of urban waste that would otherwise end in landfills, the technology produces up to 15 000 tonnes/year of alternative fuel which implies a reduction of 44 000 tons of CO2, thus contributing to climate change mitigation and biofuel production (2009/28/EC Renewable Energy Directive). The project’s programme for disseminating and communicating project results focused on the advantages of the new technology compared to currently used technologies, with regard to environmental issues, economic viability and social acceptance. During the project’s implementation, more than 300 people (mainly from public authorities and private companies) visited the pilot facility.

Diesel R technology has a huge potential in terms of replication in other municipal districts. The project has given this technology a definitive step towards its future application in 100% profitable and exploitable commercial facilities. The new technology has found a higher public acceptance than conventional waste management technologies, due to the absence of nuisance smells and particles. In addition, the final product of the process, an alternative diesel fuel, has quite good commercial acceptance.
