The specificity of horticultural production makes it possible to use substrates based on compost from municipal and industrial waste, particularly in the cultivation of ornamental plants. Experiments were conducted in the years 2005–2007. Six horned violet cultivars (<em>Viola cornuta  </em>L.) from Patiola F1 group and four substrates were used in them: I – sphagnum peat; II – substrate from peat and compost 1 (1:1 v/v); III – substrate from peat and compost 2 (1:1 v/v); IV – coconut fibre. Compost 1 was prepared using municipal sewage sludge (35%), potato pulp (35%) and straw (30%). Compost 2 was prepared using municipal sewage sludge (35%), potato pulp (35%) and sawdust (30%). Composts after 10 months of composting were used in the research. The addition of municipal sewage sludge composts did not cause observable adverse changes in plants grown. Composts made from municipal sewage sludge are rich in nutrients. Plants that are grown in substrates with the addition of composts and in a peat substrate grow and develop properly without the necessity of introducing top dressing.

Effects Of Media

The purpose of the studies was to determine the effects of media containing composts from sewage sludge and potato pulp on the flowering and decorative value of 'Butterfly Yellow with Blotch' parviflorous pansy. In the experiment 14 potting media, including 12 media made of 4 composts, were tested. The percentage of compost mixed with sphagnum peat was 25%, 50% and 75%. The components of particular composts were as follows: I - municipal sewage sludge 70% and straw 30%; II - municipal sewage sludge 70% and sawdust 30%; III - municipal sewage sludge 35%, potato pulp 35% and straw 30%; IV - municipal sewage sludge 35%, potato pulp 35% and sawdust 30%. Two control potting media were used: 1 - sphagnum peat with Osmocote Exact Lo-Start at the dose 5 g×dm<sup>-3</sup> and 2 - sphagnum peat with Azofoska at the dose 2.5 g×dm<sup>-3</sup>. There was no top-dressing during cultivation. The pansies for whose cultivation a slow-release fertiliser was used turned out to have most flowers, but the plants cultivated in compost with peat at the ratio 1:1 had equally abundant flowering. At the generative stage, the pansies in control media were the most decorative and those growing in 25% of compost I, 75% of compost II and 50% of compost III and IV. On the basis of plant valuation scale, quality assessment and the abundance of flowering it was found that the media containing 50% of composts were optimal for pansy cultivation.

Effects Of Media

The aim of the studies was to determine the effects of media with composts, based on sewage sludge and potato pulp, on the growth and conformation of the cultivar 'Butterfl y Yellow with Blotch'. In the experiment 14 potting media, including 12 media made of 4 composts, were tested. The percentage of compost mixed with sphagnum peat was 25%, 50% and 75%. The components of particular composts were as follows: I - municipal sewage sludge 70% and straw 30%; II - municipal sewage sludge 70% and sawdust 30%; III - municipal sewage sludge 35%, potato pulp 35% and straw 30%; IV - municipal sewage sludge 35%, potato pulp 35% and sawdust 30%. Two control potting media were used: 1 - sphagnum peat with Osmocote Exact Lo-Start at the dose 5 g×dm<sup>-3</sup>, and 2 - sphagnum peat with Azofoska at the dose 2.5 g×dm<sup>-3</sup>. There was no top-dressing during cultivation. The potting media used for pansy cultivation were rich in essential nutrients and in certain media macroelement content exceeded the limits recommended for the species with great nutrient requirements. The effects of the media on the growth, conformation and foliage of pansies depended on compost composition and its pecentage in a medium. The composts used for the media were found to be suitable for pansy cultivation. Despite smaller leaf rosettes in comparison with control plants, the pansies from compost media grew well and showed no disease symptoms.

Municipal sewage sludge compost (MSC) is used as an alternate peat media in ornamental plants. Ornamental producers have demonstrated skepticism toward the use of MSC as a substratum because they understand it may contain pathogenic microorganisms. The objective of this study was the identification of fungi in MSC obtained from the compost plant of the Acueducts and Sewage Authority ¡n Mayagüez, Puerto Rico. The samples were obtained from different piles. The treatments were four samples of MCS and one control, 100% peat, replicated three times. Serial dilutions from 10(-1) to 10(-4) were developed by means of 10 g of each treatment. The medium OHIO was used to grow fungi at 28 and 45° C. For each treatment of MSC and peat, fungi growth was observed at 28° C; at 45° C growth was observed only in the control. Three colonies were selected at random from petri dishes; 21 species of fungi were identified from genus: Aspergillus sp., Conidiobolus sp., Curvularia sp., Mucor sp., Penicillium sp., Rhizopus sp., Trichoderma sp., and Scopulariopsis sp. The fungi identified in MSC were classified as saprophytic and antagonistic. Aspergillus fumigatus Fresen, a species reported as a human pathogen, was identified in peat.

The effect of composts from potato pulp and municipal sewage sludge for changes of microelements in the soil during incubation The total and soluble content of microelements in the soil was described in the laboratory experiment. The soil was incubated with three doses of composts with a participation of municipal sewage sludge and potato pulp. The obtained results of the experiment pointed that all the composts increased an average total content and the forms soluble in 1 M HCl of microelements in the soil in comparison with the control. In the majority of the variants, the composts made with the 70% participation of municipal sewage sludge and 30% addition of straw or sawdust caused an increase of the content of the analyzed elements in the soil than the composts with the 70% participation of potato pulp and 30% addition of straw or sawdust. The differences are connected with a higher content of microelements, which were put in the soil, with the composts with the 70% participation of municipal sewage sludge and 30% addition of straw or sawdust. There are no differences in the formation of the content of microelements in the soil, which were depended on the type of the structural - formative component during the production of composts. The quantity of the composts' dose had an influence on the formation of the participation of the soluble form of microelements in the total content in the soil. The participation of the soluble form of cadmium, cooper, manganese and nickel in the total content in the soil increased along with increasing the dose of composts. The content of the total forms in the soil incubated with the composts included in the standard for the light soils.

Circulating Fluidized Bed Combustion

Recently, more and more attention has been paid to the removal of nickel ions due to their negative effects on the environment and human health. In this research, fly ash obtained as a result of incineration of municipal sewage sludge with the use of circulating fluidized bed combustion (CFBC) technology was used to analyze the possibility of removing Ni(II) ions in adsorption processes. The properties of the material were determined using analytical methods, such as SEM-EDS, XRD, BET, BJH, thermogravimetry, zeta potential, SEM, and FT-IR. Several factors were analyzed, such as adsorbent dose, initial pH, initial concentration, and contact time. As a result of the conducted research, the maximum sorption efficiency was obtained at the level of 99.9%. The kinetics analysis and isotherms showed that the pseudo-second order equation model and the Freundlich isotherm model best suited this process. In conclusion, sewage sludge fly ash may be a suitable material for the effective removal of nickel from wastewater and the improvement of water quality. This research is in line with current trends in the concepts of circular economy and sustainable development.
