2019 journal article

Evaluation of optimal model parameters for prediction of methane generation from selected US landfills

WASTE MANAGEMENT, 91, 120–127.

By: W. Sun*, X. Wang n, J. DeCarolis n & M. Barlaz n 

author keywords: Landfills; Landfill gas; Methane; Gas collection efficiency; LandGEM
MeSH headings : Air Pollutants; Gases; Methane; Refuse Disposal; Waste Disposal Facilities
TL;DR: Methane collection data from 21 U.S. landfills were used to estimate the best fit k by inverse modeling of measured methane collection data in consideration of a time-varying gas collection efficiency, and show that there is wide variation in the best estimate. (via Semantic Scholar)

Decomposition and carbon storage of hardwood and softwood branches in laboratory-scale landfills

Science of the Total Environment, 557, 355–362.

2015 journal article

Characterization of Uncertainty in Estimation of Methane Collection from Select US Landfills

ENVIRONMENTAL SCIENCE & TECHNOLOGY, 49(3), 1545–1551.

By: X. Wang n, A. Nagpure  n, J. DeCarolis n & M. Barlaz n 

MeSH headings : Air Pollutants / analysis; Electricity; Methane / analysis; Models, Theoretical; Monte Carlo Method; Solid Waste; Uncertainty; United States; Waste Disposal Facilities
TL;DR: The results indicate that landfill operators could overpay for engine capacity by $30,000-780,000 based on overestimates of collectable methane based on uncertainty in engine requirements and potential economic losses to demonstrate the practical significance to landfill operators.

2015 journal article

Decomposition and carbon storage of selected paper products in laboratory-scale landfills

SCIENCE OF THE TOTAL ENVIRONMENT, 532, 70–79.

By: X. Wang n, F. Cruz n , F. Ximenes * & M. Barlaz n 

author keywords: Landfills; Municipal solid waste; Paper products; Anaerobic decomposition; Biochemical methane potential; Carbon storage
MeSH headings : Biodegradation, Environmental; Carbon / analysis; Carbon Sequestration; Cellulose; Climate Change; Laboratories; Lignin; Methane; Models, Chemical; Paper; Refuse Disposal / methods; Waste Disposal Facilities
TL;DR: The methane yields, carbon storage factors and the extent of cellulose and hemicellulose decomposition all consistently show that papers made from mechanical pulps are less degradable than those made from chemical pulps where essentially all lignin was chemically removed.

2013 journal article

Decomposition of forest products buried in landfills

WASTE MANAGEMENT, 33(11), 2267–2276.

By: X. Wang n, J. Padgett n, J. Powell n & M. Barlaz n 

author keywords: Landfills; Municipal solid waste; Forest products; Anaerobic decomposition; Biogenic carbon storage
MeSH headings : Waste Management; Wood / chemistry
TL;DR: These results, in general, correlated well with an earlier laboratory-scale study, though NP and CC decomposition measured in this study were higher than previously reported. (via Semantic Scholar)

2013 journal article

Using observed data to improve estimated methane collection from select US landfills

Environmental Science & Technology, 47(7), 3251–3257.

By: X. Wang n, A. Nagpure  n, J. DeCarolis n & M. Barlaz n 

MeSH headings : Gases / analysis; Kinetics; Methane / analysis; Models, Chemical; Public Policy; Rain; Statistics as Topic; Temperature; Uncertainty; United States; Waste Disposal Facilities
TL;DR: The results suggest that the default k value assumed in LandGEM is likely too low, which implies that more methane is produced in the early years following waste burial when gas collection efficiencies tend to be lower. (via Semantic Scholar)

2011 journal article

Wood Biodegradation in Laboratory-Scale Landfills

ENVIRONMENTAL SCIENCE & TECHNOLOGY, 45(16), 6864–6871.

By: X. Wang n, J. Padgett n, F. Cruz n  & M. Barlaz n 

TL;DR: Wood species have unique methane yields that should be considered in the development of national inventories of methane production and carbon storage and the current assumption of uniform biodegradability is not appropriate. (via Semantic Scholar)
