Reflections on Abatement Modelling

In environmental economics it is common to add non-negative constraints on abatement, or equivalently to constrain emissions by some maximum unabated level. However, in this paper it is argued that these assumptions are both physically wrong and complicating. Also, more seriously, such constraints can rule out optimal solutions. For instance, negative NOx abatement can be optimal from the socia...

Biological abatement of cellulase inhibitors.

Removal of enzyme inhibitors released during lignocellulose pretreatment is essential for economically feasible biofuel production. We tested bio-abatement to mitigate enzyme inhibitor effects observed in corn stover liquors after pretreatment with either dilute acid or liquid hot water at 10% (w/v) solids. Bio-abatement of liquors was followed by enzymatic hydrolysis of cellulose. To distingui...

Matrix Management of Risk Abatement

In a coordinated four level attack on risk, integration of analytical procedures (i.e. Lean Optimization, PM Analysis, and Optimal Reliability) can be achieved by conducting each one against the backdrop of IONICS, a 6-step methodology facilitating matrix management and defined by: Identify risks, Order by importance, Numerate options, Introduce solutions, Control processes and Synthesize new i...

Stochastic Arable-Nitrogen Abatement from Heterogeneous Sources Cost-E ective Coastal Nitrogen Abatement

The implications of the propagation of uncertainty for the e ciency of stochastic water pollution control were analyzed. The empirical analysis focused on nitrogen pollution of the Baltic Sea from Swedish crop farms. A two moment model (mean and variance) of the distribution of coastal load was developed and integrated with an economic model of arable land-use choice. It was shown that uncertai...
