In its development, it adapted two existing technologies, In the agricultural sector, the mechanics of grain elevators provided a model for how to move solids vertical distances and in closed-loop flow arrangements. Sacony engineers modified the elevator bucket systems traditionally used by the grain industry to carry hot catalyst from the bottom to top of vessels and between vessels. 

On the other hand, it is an accepted certainty that oil, coal, and natural gas are exhaustible resources with an undoubtedly increasing price trend in the long term. For the agricultural sector, the hope of decreasing dependency on the food markets and new additional income opportunities are important driving factors. For the industry, a change in the industrial raw material basis toward renewable resources offers the way to new products, new business models, and in the end to more sustainability-so the doubtlessly attractive vision. 

As we shall see later, the industrial model was applicable to some, but not all, of agriculture. It was nonetheless applied indiscriminately as a creed rather than a scientific hypothesis to be examined skeptically. The modernist confidence in huge scale, centralization of production, standardized mass commodities, and mechanization was so hegemonic in the leading sector of industry that it became an article of faith that the same principles would work, pari passu, in agriculture. 

The three domains correspond basically to a model of society constituted of three sectors the market, the state and civil society. Each sector is based on a distinct type of rationality and may provide the individual farmer with different types of inputs for his/her deliberations regarding the farm for instance, the option of converting to organic agriculture or developing existing organic production.
