Nonparametric efficiency analysis for pollution-generating technologies under the materials-balance principle. Implements the weak-G-disposability model of Rodseth (2025) doi:10.1007/s11123-025-00768-0 and its factorially determined multi-output representation, the by-production intersection technology of Murty, Russell and Levkoff (2012) doi:10.1016/j.jeem.2012.02.005, the materials-balance cost model of Coelli, Lauwers and Van Huylenbroeck (2007) doi:10.1007/s11123-007-0052-8 and a weak-disposability reference model, with an enforced materials-balance identity, a pre-estimation feasibility audit, metafrontier decompositions, bad-output shadow prices, marginal abatement cost curves, a cross-axiom comparison harness, a global Malmquist-Luenberger productivity index and subsampling inference. Estimators are solved with 'lpSolveAPI'.
