Lowchemistry

Lowchemistry is a term occasionally used in discussions of chemical research and practice to describe efforts aimed at reducing the resource intensity and environmental footprint of chemical processes. It is not a formally defined field, and usage varies across authors and contexts.

In some interpretations, lowchemistry emphasizes lowering energy input through ambient-condition reactions, solvent minimization, and the avoidance of hazardous reagents. In others, it highlights simplified synthesis with fewer steps, higher atom economy, and greater recyclability of catalysts and solvents. The common thread is a focus on reducing waste, cost, and risk while maintaining or improving yield and selectivity.

Within the broader framework of green chemistry and sustainable chemistry, lowchemistry is often described as an aspirational or descriptive label rather than a distinct discipline. Researchers may apply tools such as solventless or flow chemistry, catalytic efficiency, process intensification, and life-cycle assessment to achieve lowchemistry outcomes.

Because the term lacks a standardized definition, it can be used inconsistently and may invite debate about the value and scope of chemistry that is “low” in energy, material use, or hazard. Proponents argue that it helps communicate a priority for safety and sustainability, while critics caution against conflating efficiency with a reduction in scientific rigor.
