This method uses a bipartite graph method (P-graph method) to describe process networks and employs combinatorial rules to find all feasible network solutions (the maximum structure) using all possible raw materials, intermediate products and products as well as all relevant technologies processing these materials.
America has natural harbours on two great oceans, access to one of the world's richest fishing areas, an abundance of every possible raw material and a huge range of farmed crops, from cold-weather to tropical.
Possible raw material can be found also from agro biomass, forest biomass and different kinds of industrial and municipal wastes.
However, there are steps that food manufacturers can take in conjunction with growers to ensure that they have the best possible raw material to keep acrylamide formation in their products as low as reasonably achievable.
Made In Space says it's been trying out possible raw materials for its printers including a substance similar to lunar soil.
"We spent two years creating the scent, first trying out all the possible raw materials, saying 'yes' to this and 'no' to that until we have narrowed it down – which took a long time".
Industrial wastes, such as fly ash and calcium carbonate from chemical manufacture, are other possible raw materials, but their use is small compared with that of the natural materials.
I use locally-sourced found objects along with imagery sourced from my online social networks and web surfing in my work, so it made sense to think of these other artists work as possible raw materials, with extra-strong layers of authorship, context, and history attached.
Facing a shortage of a raw material, a company can find an alternative raw material or create a synthetic one.
It is generally in the interest of the processing enterprise, which requires as regular a supply of raw material as possible, to ensure or promote implementation of these measures by producers.
Once a drug is being produced in a controlled way, it might be possible to introduce a slightly different raw material into the molecular assembly line, which could ultimately produce a better drug.
