“…They concluded that the dairy manure compost produced with drywall paper scrap addition had no phyto‐inhibitory effect on plant growth. Naeth and Wilkinson (2013) reported that drywall added to biosolids or manure during composting had no detrimental effects on vegetation, and the resulting compost was a good soil amendment for establishing native and non‐native plant species on reclamation sites.…”

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.

“…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].…”

“…According to several characterisation studies on construction and demolition (C&D) debris in Canada, waste drywall accounts for about 9% of the mass of waste generated from C&D waste streams [5]. In North America, it comprises between 12% and 27% of C&D waste [6,7]. In general, waste drywall can be divided into three categories based on their source.…”

“…The disposal of drywall waste to the landfill is common practice in the past, even today. When disposed to the landfill, the moist anaerobic conditions of the landfill allow anaerobic microorganisms (sulphate reducing bacteria) to degrade the sulphate component of the drywall, producing potentially toxic levels of hydrogen sulphide gas [2,7,10,11]. Hydrogen sulphide is a flammable and extremely hazardous gas with a distinctive smell of a rotten egg.…”

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.

“…In addition, studies of rocky desertification in carbonate rock areas have primarily focused on changes in the physical and chemical properties and biological species of the soils (Jiang et al, 2014). Dregne (2002) reported that soil degradation is a severe problem in rocky desertification areas because of the significant loss of nutrient elements, such as N, P and K. Furthermore, rapid vegetation degradation causes biological community simplification in rocky desertification areas and eventually results in the decline of ecosystem stability (Naeth & Wilkinson, 2013). Therefore, these areas are primarily restored through soil improvements in fertilization and vegetation restoration technologies (Jeffries et al, 2003).…”

Carbonate minerals are extensively distributed across China, and their special rock structures make them vulnerable to land damage through mining, leading to rocky desertification. Soil microorganisms play an important role in mineral weathering. However, little is known about the utilization of the mineral‐weathering microorganisms to alleviate the problem of rocky desertification in mines. In the present study, the mineral‐solubilizing bacterium NL‐11 was isolated from soil around weathered dolostones and identified as Bacillus thuringiensis based on the Biolog identification system and 16S rDNA sequence analysis. The mineral dissolution experiments revealed that inoculation with the live bacterium significantly increased the mineral sample dissolution via significantly enhancing Ca and Mg release, with increase values of 303·27 and 50·55 mg L−1 respectively, compared with that with the inactivated bacterium. Moreover, the acetic acid secreted by strain NL‐11 markedly decreased the size of particle diameter (quantified with a laser diffraction particle size analyser) through reducing pH value. The eroded traces were observed by scanning electron microscopy analysis, and the results further verified the erosional effects of this strain. In addition, this bacterium contributed to the establishment and proliferation of plants by providing nutrient elements, such as phosphorus (P) and potassium (K). Our study not only provided an efficient bacterial strain NL‐11 but also enriched the technologies to mitigate problems associated with ecological restorations of carbonate mines.
