Consider the case of Jason Rose's Alamo Biodiesel (from the Express-News):
A slightly sticky carpet in the office. Nice.
From those first small batches made in the fall of 2005, Rose has gone commercial, launching Alamo Biodiesel Inc. in a small warehouse just west of downtown at 523 Perez St., where the company is making about 800 gallons of biodiesel a day.
In the company's warehouse and office, production tanks exude what Rose calls "a faint tang of vegetable oil," but after a few minutes it permeates nostrils and clothes. The carpet in the office is slightly sticky, and operations manager Raul Sanchez says he goes home smelling like French fries.
