“…The condition of high temperature in the compost systems facilitate in decomposition of organic matter and elimination of pathogenic microorganisms. As reported by Saludes [15], the initial rise in temperature was due to heat generated by the presence of large quantity bacteria responsible for the initial decomposition of organic matter. Total count of thermophiles bacteria shows decrease of colony number as the temperature drops.…”

In this study, production of indigenous microorganisms (IMO) and effect on addition of IMO in composting process were done. Production of IMO was done in a series of steps to allow propagation of beneficial microorganisms. Effect of IMO addition in composting process was investigated by having 4 treatments; 1) rice straw without IMO nor manure and rice bran, 2) rice straw with IMO only, 3) rice straw with manure and rice bran, 4) rice straw with IMO, manure and rice bran. Production of IMO using cooked rice yields white molds. Addition of IMO during composting did not affect temperature increment. However, there were differences in numbers of microorganisms found during each stages of composting. Initial composting stage was dominated by mesophilic bacteria and actinomycetes, followed by thermophilic bacteria and later by actinomycetes upon composting completion. In conclusion, this study showed that IMO addition in composting increased microorganisms which are responsible in organic decomposition.

“…McMahon et al (2008) composted various types of C&D wood waste with poultry manure and green waste and concluded that the compost they produced could improve plant growth. Saludes et al (2008) reported higher Ca levels in the final compost after co‐composting dairy manure with paper scraps from drywall production at a manure/paper ratio of 2.5:1 (fresh weight). They concluded that the dairy manure compost produced with drywall paper scrap addition had no phyto‐inhibitory effect on plant growth.…”

Co-composting of Beef Cattle Feedlot Manure with Construction and Demolition Waste

With increased availability of dried distillers' grains with solubles (DDGS) as cattle feed and the need to recycle organic wastes, this research investigated the feasibility of co-composting DDGS cattle feedlot manure with construction and demolition (C&D) waste. Manure was collected from cattle fed a typical western Canadian finishing diet (CK) of 860 g rolled barley ( L.) grain, 100 g barley silage, and 40 g vitamin and mineral supplement kg dry matter (DM) and from cattle fed the same diet but (DG manure) with 300 g kg DM barley grain being replaced by DDGS. The CK and DG manures were co-composted with and without C&D waste in 13 m bins. Compost materials were turned on Days 14, 37, and 64, and terminated on Day 99. Adding C&D waste led to higher compost temperatures (0.4 to 16.3°C, average 7.2°C) than manure alone. Final composts had similar total C, total N, C/N ratios, and water-extractable K, Mg, and NO content across all treatments. However, adding C&D waste increased δC, δN, water-extractable SO, and Ca contents and decreased pH, total P (TP), water-extractable C, N, and P and most volatile fatty acids (VFA). The higher C&D compost temperatures should reduce pathogens while reduced VFA content should reduce odors. When using the final compost product, the increased SO and reduced TP and available N and P content in C&D waste compost should be taken into consideration. Increased S content in C&D compost may be beneficial for some crops grown on S-deficient soils.

“…Application as a compost-bulking material is one of the potential end markets identified for recycled drywall. The growing demand for long-established bulking agents such as sawdust and woodchip as candidate raw materials for biofuel production has shifted interest into finding alternate bulking materials [28]. Therefore, recycled drywall could be co-composted with organic wastes such as municipal solid waste, biosolids, and animal manure.…”

“…Saludes et al [28] reported that using clean drywall scrap from manufacturing sites as a bulking agent for diary manure compost had no detrimental effect on the compost process after a period of 28 days. No phyto-inhibitory effects were detected at the end of the final compost with a germination index of 99%.…”

“…Ammonia volatilisation during composting is particularly noted to be influenced by several factors, including ammoniacal nitrogen concentration, pH, temperature, moisture content, and aeration rate [38,39]. The electrical conductivity (EC) increased significantly when co-composting gypsum drywall with diary manure [7,28]. Electrical conductivity (EC) value greater than 4 dSm −1 as found in manure composts indicate excess salinity [40,41], which has the potential of inhibiting germination and plant growth [7].…”

The incessant disposal of drywall waste, generated predominantly from construction and demolition sites, has been associated with many environmental problems. In landfill sites, it has long been linked with the generation of hydrogen sulphide, a toxic and foul-smelling gas, while the incineration of this waste results in the potential release of sulphur dioxide gas, a contributor to acid rain formation. The traditional disposal methods also result in the loss of a valuable resource. Therefore, proper management of this waste through recycling programs and subsequent returns to the end market will ensure that a valuable resource is not lost and that environmental impacts are mitigated. Many potential end markets have been identified for recycled drywall. The application as a bulking agent for composting is one of these markets, which could also provide additional calcium and sulphur nutrients to the soil. Despite the benefits of drywall waste recycling, certain challenges have crippled its recycling rate in North America. This review summarises the current situations with drywall recycling and disposal, existing markets, and the availability of competing markets. Furthermore, the potential use of drywall as a compost-bulking agent is discussed. Finally, a possible solution to improving the recycling rate and market demands for drywall is presented.
