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.

2014 journal article

Chemical Changes during Anaerobic Decomposition of Hardwood, Softwood, and Old Newsprint under Mesophilic and Thermophilic Conditions

JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY, 62(27), 6362–6374.

By: F. Cruz n , D. Yelle *, H. Gracz n & M. Barlaz n 

author keywords: anaerobic decomposition; CuO oxidation; lignin; HSQC; NMR
MeSH headings : Anaerobiosis; Biotechnology; Cellulose / chemistry; Lignin / chemistry; Magnetic Resonance Spectroscopy; Plants / chemistry; Wood / chemistry
TL;DR: The 2D NMR and chemical degradation methods revealed slight reductions in β-O-4 linkages for HW and ONP, with no depolymerization of lignin in any substrate. (via Semantic Scholar)

2013 journal article

Measurement of carbon storage in landfills from the biogenic carbon content of excavated waste samples

WASTE MANAGEMENT, 33(10), 2001–2005.

By: F. Cruz n , J. Chanton * & M. Barlaz n 

author keywords: Landfill; Carbon storage; Municipal solid waste
MeSH headings : Biodegradation, Environmental; Carbon / analysis; Cellulose / metabolism; Kentucky; Lignin / metabolism; Methane / metabolism; North Carolina; Polysaccharides / metabolism; Refuse Disposal / methods; Waste Disposal Facilities
TL;DR: The fraction of biogenic carbon that is not reactive in the landfill environment and therefore stored was derived for samples of excavated waste by measurement of the total organic carbon, its biogenic fraction, and the remaining methane potential. (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)

By: F. Cruz n  & M. Barlaz n 

MeSH headings : Biodegradation, Environmental; Bioreactors; Cities; Kinetics; Laboratories; Methane / analysis; Refuse Disposal / methods; Waste Products / analysis; Water Pollutants, Chemical / chemistry
TL;DR: The effect of landfill waste diversion programs on methane production was explored to illustrate the use of component-specific decay rates. (via Semantic Scholar)
