Bio-based adhesive with alkyd resin entirely derived from natural feedstock

Alkyd resins are one of the commercially most mature resins. They are considered near-green because of significant amount of natural ingredient. If alkyd resins are produced entirely with natural ingredients, they offer the complete bio based adhesive system. Typically the alkyd resins have over 75% natural ingredients as they are derived from vegetable oils and …

Biogas Enrichment by Moderate Pressure Scrubbing for Optimum Utilization

Energy / Biotech, Chemicals, Process

The Challenge / Concern: Efficiency of utilization and handling of biogas depends on its methane content. Typical biogas has 35% inert content of primely carbon dioxide. About 65% methane leads to increased handling costs and heavier equipments. . Also, biogas has lower calorific value and lower burn rate due to the inert content. Brief (and …
