Agricultural solid wastes in the southern part of Jordan were estimated and classified. Data collection method was used to determine the types and quantities of different agricultural solid wastes. Human excreta and cattle manure were found to be serious environmental problems in the region. Chemical analysis of different solid wastes showed variable organic and nitrogen content which affect the selection of treatment process. Anaerobic digestion (AD) was tested and found to be a suitable unit operation to treat a wide variety of agricultural solid wastes. Biogas production rate from AD ranged from 0.3 m 3 /kg COD to 0.61 m 3 /kg COD which is considered 80% to 90% of yield. The optimum C/N ratio and TVS for AD was found to be 22 ± 2 and 70% ± 5%, respectively. The amount of energy that can be produced from energy crops and animal manures was estimated to be 12.8 Mtoe and 0.34 Mtoe, respectively. Methane biogas production rate was estimated to be 37 m 3 /ton for substrate consist of mixture of different agricultural solid waste of 50% wastewater, 40% Cattle manure, 5% straw and 5% sawdust.

“…240-litre) are more suited to garden waste than small (23-litre) UK type food waste bins. But the addition of non-woody garden waste does not necessarily need to be a disadvantage as apples and grass cuttings are good substrates for anaerobic digestion ( [48], [34], [36]). The amount of organic waste collected in tonnes is plotted in Figure 6 for all four local authorities in 12 consecutive months.…”

The European Commission is tightening waste laws, and many local authorities, particularly in countries with low recycling rates, face the question of what system to introduce for the sourceseparate collection of food waste from householders. This study provides empirical data in form of fuel consumed and waste yield from four councils that already have source separate organic waste collections in operation. Two systems were compared: (i) door-to-door collection and (ii) bring systems where the householder walks to the bin in her/his street to drop off organic waste. Fuel consumption for the collection operation with the bring system was dramatically lower compared to the door-to-door system. Organic waste yield was constant over the observation year in the door-to-door system employing small 20-to 30-litre bins, but increased notably in the summer with the bring system that used 240-litre bins. The metric used to quantify seasonality was the summer/winter yield ratio. As commercial waste companies do not normally allow the making of data public, this is a rare opportunity to learn from collection systems currently in operation.

“…Zhang and Zhang (1999) studied the anaerobic phased solids digester system for the conversion of rice straw to biogas. Ligno-cellulosic Yu et al (2002). The digester employed in this study was 8 m 3 solid phase reactor (harbouring 155 kg of feedstock) coupled with methane phase reactor consisting of inert commercial packing media used to facilitate the bacterial attachment and growth.…”

“…Maximum loading rate of this UAF digester was determined to be 2.7 kg of COD/m 3 per day. Yu et al (2002) also studied the effects of temperature on the biomethanation efficiency by using heated upflow anaerobic filter (UAF) in one of the reactor. Higher gas production reported in the heated UAF was due to the higher COD conversion.…”

Fermentable components of municipal solid wastes (MSW) such as fruit and vegetable wastes (FVW), leaf litter, paddy straw, cane bagasse, cane trash and paper are generated in large quantities at various pockets of the city. These form potential feedstocks for decentralized biogas plants to be operated in the vicinity. We characterized the fermentation potential of six of the above MSW fractions for their suitability to be converted to biogas and anaerobic compost using the solid-state stratified bed (SSB) process in a laboratory study. FVW and leaf litter (paper mulberry leaves) decomposed almost completely while paddy straw, sugarcane trash, sugarcane bagasse and photocopying paper decomposed to a lower extent. In the SSB process between 50-60% of the biological methane potential (BMP) could be realized. Observations revealed that the SSB process needs to be adapted differently for each of the feedstocks to obtain a higher gas recovery. Bagasse produced the largest fraction of anaerobic compost (fermentation residue) and has the potential for reuse in many ways.
