“…Additionally, results from long-term laboratory incubation experiments with biowaste compost revealed a high N-mineralization potential of 65% of the total compost N in vineyard soils (Nendel et al, 2004) and thus a priming effect in the first 2 y after compost application of 30 Mg ha -1 dry mass (Nendel and Reuter, 2007). However, it can be taken from other studies, that the release of compost-derived N was much lower especially under field conditions and agricultural land use and supplementary inorganic-N fertilization was subsequently necessary for plant productivity Erhart et al, 2005;Hartl and Erhart, 2005). Consequently, mineral fertilization, except N, in agriculture may be substituted and thus reduced through the application of biowaste composts.…”

Soil-quality parameters, such as soil organic matter (SOM) and plant-available nutrient contents, microbial properties, aggregate stability, and the amounts of heavy metals were carried out in arable soils of different rotation schedules applied with a total of 50 Mg dry mass ha -1 biowaste compost relative to an untreated control. This was investigated during a 10 y period from 1994 to 2004. Overall, soil-quality parameters studied appeared to be promoted by biowaste-compost application. This was evidenced for example by a remarkable increase of SOM and total N content of ≈ 15%-20% relative to the control. Subsequently, amounts of soil microbial biomass and alkaline phosphatase activity were significantly increased as well. In addition, biowaste-compost application revealed an increase of plant-available P and K contents and aggregate stability in soil. There was, however, no treatment effect for net N-mineralization rates. Moreover, in soils of maize and sugar beet rotation schedule a slight decrease was found. Heavy-metal contents of Pb and Zn were significantly increased in all compost-treated soils, whereas no significant increase of Cd and Cu contents was measured. However, the investigated amounts were far below of the limits of the German Biowaste Ordinance. It is finally recommended, that biowaste compost may sustain and improve soil quality in agriculture when N nutrition will be considered.

“…The raw substrates OM levels constancy during incubation can be explained by the organic matter low mineralization prior amendment or dilution. Thus, decreases in OM levels can be explained by their biodegradation by soil microflora (Beck-Friis et al, 2003;Erhart et al, 2005). The increase in potassium content can be explained by the binding of K + ions from the mineralization of organic matter on the exchange complex and the decrease of cations exchange capacity by the organic matter degradation (Halilat et al, 2000).…”

“…Thus, during the process of anaerobic digestion, only part of the original organic matter is completely degraded, the rest can be considered as a potential fertilizer of agricultural land (Erhart et al, 2005).…”

We investigated the fertilizing potential of three agro-industrial wastes (Compost (C), Dehydrated Manures (DM) and Digestate (D)) on soil properties, on seeds germination and the plants growth. Results showed that the addition of wastes modified several soil properties as pH, Electrical Conductivity (EC), Water Retention Capacity (WRC) and Soil Organic Matter (SOM). Hence, SOM increase from 1.5% in unamended soil to 2, 2.3 and to 3.1% in soils amended with (D), with (DM) and with (C) respectively. A fast SOM biodegradation was illustrated in presence of compost where we noted a decrease of 20% of initial organic matter content. Besides, wastes improve strongly microbial and respirometric soil activities mainly in presence of DM and D. These same wastes stimulate seeds germination of two standard plants species (Tomato (Lycopersicon esculentum) and Alfalfa (Medicago sativa)). The growth levels of three cultivated plants species (Wheat (Triticum durum), Sorghum (Sorghum bicolor) and Alfalfa (Medicago sativa)) were enhanced in presence of wastes than those irrigated with water.

“…The low market value of organic fertilizers may be attributed to the low productivity of compost [26,27]. Some researchers suggest that combinations of organic materials and mineral fertilizers may improve nutrient efficiency and increase the crop yield [28].…”

Taiwan's Environmental Protection Administration (EPA) has enacted a food waste recycling policy since 2003 as an alternative of landfill and incineration for the final disposal of municipal solid waste. Recycled food waste is currently seen as a valuable material, especially when appropriate technology is developed. This paper conducts a cost/benefit analysis based on six cases of food waste composting plants in Taiwan, finding that (1) the composting of food waste may yield the most net benefit compared to other applications of today; (2) the production cost of compost ranges from NT$ 2897-23,117/tonne; (3) the adoption of more automatic technology may reduce operation costs and, thus, a closed composting system with mechanical aeration may be more cost effective; (4) the output is a determinant of affecting production costs and private firms are more competitive in production costs than government-affiliated composting units; (5) all of the government-affiliated composting units face a negative profit and thus they are required to make use of the market value of the produced compost to achieve economic viability; and (6) a subsidy to the compost producer is needed to expand the market demand as the food waste recycled can save the disposal cost of municipal solid waste (MSW) incineration.
