The main objective of the research is to quantify the main factors controlling bio-drying and the quality of SRF using a semi-industrial rotary drum bio-reactor. The project also aims to optimise the bio-drying process and the quality of the end product and also assess the effect of using SRF in cement production on the quality of cement. The research is carried out using the bio-reactor developed and owned by ISOTECH ltd

Co-composting of animal manure and sludge, with trimming from municipal waste. Production of soil conditioner
The aim of this research project was the identification of the best conditions for the production of a marketable soil conditioner, by composting municipal trimmings with chicken and goat-sheep manure, as well as with sludge from a wastewater treatment plant. Special focus was given to the reduction of pathogens and the activity of weed seeds, throughout the composting-maturation process and the final product.
The project was co-financed by Research Promotion Foundation (Pr. No: AIEFO/1104/16). The Research Team, included scientists and representatives from the organizations: Isotech Ltd (host organisation), Research and Consultancy, National Technical University of Athens-Greece, Imperial College of London-UK, Proplan Ltd, Industrial Consultants, Ecozoe Ltd, Bio-cultures and Ergates Community, Nicosia, Cyprus.
The research was mainly executed at the premises of Proplan Ltd, where windrows of different ratio between the four organic substrates (trimmings, goat, chicken manure, sludge), were created. Based on the activity of the microorganisms, as monitored by the temperature of the pile and the concentration of oxygen, the piles were turned regularly to avoid reduction of humidity less than 35% and oxygen concentration less than 10%.
The research was based on a factorial experimental design, out of which the scientific team proceeded with the development and assessment of 60 experiments with piles and 18 experiments with the bioreactor (in vessel composting).
From the seasonal experiments, the following results were conducted, as far as it concerns the best performing composting piles:
1. Trimmings – Goat and Sheep manure
a. Spring: Best analogy 30% manure and 70% trimmings, with 50% moisture
b. Summer: Best analogy 30% manure and 70% trimmings, with 40-50% moisture
c. Autumn: Best analogy 35% manure and 65% trimmings, with 40-50% moisture
d. Winter: Best analogy 40% manure and 60% trimmings, with 40% moisture
2. Trimmings – Chicken manure
a. Spring: Best analogy 20% manure and 80% trimmings, with 40% moisture
b. Summer: Best analogy 15% manure and 85% trimmings, with 50% moisture
c. Autumn: Best analogy 25% manure and 75% trimmings, with 40-50% moisture
d. Winter: Best analogy 30% manure and 70% trimmings, with 40% moisture
3. Trimmings – Sludge-Municipal Wastewater Plant
a. Spring: Best analogy 15% sludge and 85% trimmings, with 40-50% moisture
b. Summer: Best analogy 15% sludge and 85% trimmings, with 50% moisture
c. Autumn: Best analogy 20% sludge and 80% trimmings, with 40-50% moisture
d. Winter: Best analogy 25% sludge and 75% trimmings, with 40% moisture
The above results with minor differences were produced by both the windrow composting process and the in vessel composting process. The in vessel composting was less vulnerable to fluctuations in temperature and moisture, and easier to control, while the composting period for most of the successful experiments, was approximately 20 days, while the windrow active composting phase lasted for more than 40 days.
The experimental series dedicated for the identification of the minimum quantity of a windrow composting pile, revealed that for the climatic conditions of Cyprus, 500 kg of trimmings during winter time (mean daily T= 10oC) and 300 kg of trimmings during summer time (mean daily T= 30oC). This quantity, with the addition of one of the three organic substrates in the percentage prescribed, presents the minimum amount of organic substrate, necessary to support and maintain the thermodynamic and biological parameters of the composting process, in order to produce a stable and of acceptable quality final product-compost. Smaller piles will not support elevation of temperatures more than 40 oC, especially during winter time.
The germination of weed seeds in organic substrates, especially in goat and sheep manure, minimizes its value and poses extra cost in agriculture. Several experimental series revealed that the piles with the analogies in trimmings and manure, as presented above, could reduce the germination of the four most usual weed seeds of Cyprus, from 90 to 100%. The same piles showed a reduction of pathogens (E.coli) during the process, up to 100%.
The results of the application of the final product from the above mentioned successful piles to several agricultural plants, showed a raise in productivity of vegetables, up to 100%, compared to the productivity of the soil without soil amendments.

“Development and pilot application of innovative techniques for the treatment of industrial sludge, containing dangerous substances with focus on heavy metals”. (June 2001 – June 2003)
Partners: National Technical University of Athens (Department of Chemical Engineerign) and ISOTECH ltd Environmental Consultants-Researchers. Several techniques and materials for the stabilization/ solidification of heavily polluted industrial sludge, were tested. A multicriteria analysis was developed to identify the best available technique to manage industrial sludge with high concentration of heavy metals. Several characterization techniques for the evaluation of raw and treated sludge as well as the final products, were also tested. The final products after the application of all waste treatment techniques, were compared with the limits set by the relevant EU regulations in order to identify the possible end users or/and disposal sites.
