Feedstock Logistics

A multi-bale handling unit offers an advantage for the efficient hauling of round bales. Two empty racks on trailers are left at a satellite storage location for loading while a truck tractor delivers two loaded racks to the biorefinery, thus uncoupling the loading and hauling operations and increasing the efficiency of both. The projected 10 min trailer exchange time equals the projected 10 min unload time at the biorefinery achieved by lifting off the two full racks and replacing them with two empties, a technology adapted from the container shipping industry. A concept is presented for a bale loader that latches onto the rack/trailer and loads bales into the bottom tier chambers. This machine will load 10 bales into the rack on the front trailer by attaching on to the front of the trailer and 10 bales into the rear trailer by attaching onto the rear. A telehandler removes bales from single-layer storage and places them in the bale loader to load the bottom tier compartments. The top tier compartments are loaded directly from the top. Expectations are that an experienced operator can average 9 loads in a 10 h workday, and load-out cost is estimated as 3.61 USD/Mg, assuming the average achieved load-out productivity over annual operation is 60% of optimum productivity (24 Mg/h) equal to 14.4 Mg/h. Cost increases to 4.81 USD/Mg when the productivity factor drops to 45%, and cost is 3.09 USD/Mg for a factor of 70%.

Letters Of Credit

Soft clauses in letters of credit make the issuing bank’s obligation conditional upon some event or certification that is in the control either of the applicant, or some agent, entity, or organisation in the applicant’s country. Such clauses make an apparently irrevocable letter of credit into what is, in essence, a conditional undertaking dependent on the applicant’s approval. Soft clauses are not always a vehicle for fraud—there may be genuine reasons for their inclusion—but they certainly make it easy for an applicant to ensure that the issuing bank does not pay the beneficiary. This chapter will consider the problems caused by the use of soft clauses, some possible solutions, and it will suggest alternatives, some of which look to the past (bills of exchange/time drafts), some to the present (open account and standby letters of credit), and some to the future (the advent of blockchain technology).
