“…Another concept is the 'Protect' theory, in which the bioavailability of heavy metals is controlled by the inorganic fraction in sludge, which is adsorbed onto soil particles in an invariable ratio once sludge is added to soil as an organic fertilizer. Therefore, changes in the active form of heavy metal in sludge and its release potential to soil are independent of time (Frost and Ketchum, 2000;McBride, 2003).…”

“…It contains low concentration of heavy metals (Cu, Fe, Mn, Zn, Cr, Ni, Co, Pb) except for Cd which is a little higher as compared to typical metal content in SSs (Table 1) (Fytili and Zabaniotou, 2008). However, the organically bound metals in SS are less available than more mobile metal salts found in commercial fertilizers (Frost and Ketchum Jr. 2000). This was found when the dried SS was added to deionized water or nutrient solution.…”

Sewage sludge (SS) originating from communal wastewater is a hazardous material but have a potentially great nutritive value. Its disposal after treatment in agricultural lands can be a very economical and safe way of utilization once fast growing, high biomass, perennial plants of renewable energy production are cultivated. Szarvasi-1 energy grass (Elymus elongatus subsp. ponticus cv. Szarvasi-1), a good candidate for this application, was grown in hydroponics in order to assess its metal accumulation and tolerance under increasing SS amendments. The applied SS had a composition characteristic to SS from communal wastes and did not contain any toxic heavy metal contamination from industrial sludge in high concentration. Toxic effects was assessed in quarter strength Hoagland nutrient solution and only the two highest doses (12.5-18.75 g dm -3 ) caused decreases in root growth, shoot water content and length and stomatal conductance whereas shoot growth, root water content, chlorophyll concentration and the maximal quantum efficiency of photosystem II was unaffected. Shoot K, Ca, Mg, Mn, Zn and Cu content decreased but Na and Ni increased in the shoot compared to the unamended control. The nutritive effect was tested in 1/40 strength Hoagland solution and only the highest dose (12.5 g dm -3 ) decreased root growth and stomatal conductance significantly while lower doses (1.25-6.25 g dm -3 ) had a stimulative effect. Shoot K, Na, Fe and Ni increased and Ca, Mg, Mn, Zn and Cu decreased in this treatment. It was concluded that SS with low heavy metal content can be a potentially good fertilizer for high biomass non-food crops such as Szarvasi-1 energy grass.

“…However, the heavy metal concentrations did not exceed the limits in Part 503: Standards for the use or disposal of sewage sludge (EPA 2007). Furthermore, the metals in treated sludge were generally organically bound and less available for plant uptake compared to the more mobile metal salt impurities in commercial fertilizers (Frost and Ketchum 2000). On the other hand, the increase in Ni concentration was not significant (p > 0.05).…”

“…In Malaysia, treated sludge is currently being disposed of in landfills although previous research has shown that treated sludge is rich in plant nutrients such as nitrogen, phosphorous and potassium, and organic matter which can encourage healthy plant development and growth (Frost and Ketchum 2000). However the landfills which are currently being used to accommodate treated sludge are overloaded and the number of new lands available as landfills is limited in the country.…”

There is the inevitable increase in domestic and industrial waste with the increase in world population. The end products from the waste treatment plants are mounting and we are now faced with the inevitable end of one day being surrounded by our waste. Therefore it is crucial for us to find possible applications or uses for this waste. A social perception study was conducted by our research team to obtain acceptable uses of sewage sludge and treated waste water. In this research the possible application of sewage sludge as fertilizer for non -food crop such as the grass in the golf course was studied. The results show that using sewage sludge as fertilizer in golf courses may be an amenable application; as test conducted on soil post sludge application showed no significant threat in the increase of heavy metals and pathogens in soil.
