Forty-three businesses provided pricing information for their biochar product (Table 1). The
companies were spread out across North America, Europe, Oceania, Asia, and Africa (though
interestingly none in Latin America); however, over half of these companies were located in the
United States (23) with only the UK, Germany, and the Philippines home to more than one
company. Based on survey responses and web research, it was not always clear whether the
prices quoted were retail (point of final sale) or wholesale/producer prices (that the
manufacturer of the biochar could expect to obtain). As most businesses appear to be selling
biochar or biochar-containing products in small packs, large differences between producer
prices and retail prices are to be expected.
