For environmental protection, papers that are outside the scope are those that lack engineering aspects, including those that:

- Use experimental techniques primarily to prepare and/or characterise various materials without considerations of process engineering design and practice;

- Present primarily laboratory experiments of the effects of different parameters on behaviour of materials and pollutants (e.g. pH, temperature, mass of adsorbent, etc.) without further insights into the implications for engineering design and practice;

- Focus primarily on adsorption models and curve fitting (e.g. Freundlich, Langmuir etc.); and
