“…The achieved prices are rather high, when compared to the average selling price of 4 EUR/Mg for certified (RAL) bio-waste compost in Germany [31]. It could be argued that these high prices can only be justified by the composts high quality and low contamination levels (see Table 4).…”

While several EU member states have working compost markets, only about one third of the bio-waste, around 35 Mio tons is used to produce compost, and to some degree, biogas. The major part is still incinerated or landfilled together with other waste. This paper proposes the improvement of existing and the creation of new compost markets based on the integration of biochar and the implementation of obligatory recycling targets with flexible implementation approaches. Based on a literature review, the production of compost with biochar reduces some of the nitrogen and carbon losses and accelerates the composting process. This indicates economical benefits for the compost producer and the farmer, as well as reduced greenhouse gas emissions. An obligation to recycle organic waste, may it be on a national or on EU level, together with the implementation of appropriate collection systems, could provide the economic and societal base to mobilize the currently unused bio-waste. Should this scenario be realized, the annual amount of biochar-compost out of bio-waste could be used to serve around 3.7% of all arable land in the EU. This would demand no large-scale application, but instead specific uses for specific soil-crop constellations.Resources 2015, 4 458

“…How these certification schemes will be regarded in the revision of national and EU regulations remains to be seen. However, based on the positive experience with voluntary compost certifications and their influence on the establishment of compost markets [27,31], it would make sense to recognize their potential role.…”

“…They suggest that mechanically sorted and shredded MSW in turned windrows is the favorite option according to the cost/benefit analysis. Meyer-Kohlstock et al [25] evaluate the cost and benefit of composting based on a recent survey of some German composting plants. Some lead to stricter regulations on air quality, or a difficult building ground, or the selection of a complex technology which will increase investment and operating costs.…”

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.
