“…In addition, Colin et al [17] and Sankaran et al [18] used bacteria to retrieve effluents generated from the ethanol industry, while Akram et al [10] assessed the potential of vinasse for biofuels production. Another use of the vinasses is the production of livestock feed [5,[19][20][21][22].…”

One of the byproducts generated in the cane sugar production is molasses, which is used for ethanol distillation. However, one of the problems of distilleries is vinasse. Vinasse is highly water pollutant and is dumped untreated in lakes or rivers and damages the environment. The company FALA developed a pilot plant that uses vinasse to produce a type of livestock feed called MD60. In this paper, the impact of the pilot plant’s scale-up in the key processes of the company’s supply chain is analyzed. With the help of a sensitivity analysis, this study finds the values that would allow the company to improve its order fulfillment indicator and to increase profits, assuming an expected demand by the introduction of this new product into the market. The results show that (1) the pilot plant fulfills 32% of the orders, (2) according to the current vinasse storage capacity, it is possible to fulfill up to 77% of the orders by scaling up the pilot plant, (3) to satisfy 100% of the orders, it is necessary to use all the vinasse generated, and (4) the highest profit is reached by processing all the vinasse and by considering the upper sale price.

“…To create a balance between food versus fuel production from lignocellulosic residues, adequate land use, judicious usage of grain and corn/cane crop residues is essential [153]. Mathews et al [153] presented a sugarcane 'feed+fuel' biorefinery model, which produces bioethanol and yeast biomass, a source of single-cell protein (SCP), that can be used as a high-protein animal feed supplement. The yeast SCP, which is synthesized as a part of the process of producing cellulosic bioethanol from sugarcane can be used as a supplement for grass in the feed of cattle grazing on pasture and thereby potentially release land for increased sugarcane production, with minimal land use change effects.…”

“…We often use emergy analysis method to evaluate of the energy efficiency and potentials of the agricultural waste [2,3], and to assess the agricultural systems with different scales [4,5]. Normally，via mainstream monetary approach, extensive dairy-mushroom system analyses has been conducted, aiming to reveal the economics beneficial result.…”

An ecological energetic evaluation is presented in this paper for the dairy-mushroom system in Beijing Miyun reservoir catchment in the year 2010. It developed a system diagram for the dairy and mushroom productions based on Odum's unified measure. Conventional systems indices of the emergy yield ratio (EYR), emergy investment ratio(EIR), environmental load ratio(ELR) and environmental sustainability index(ESI) are introduced for congregated systems ecological assessment. The overall diary-mushroom system is shown with outstanding production competence compared with other agricultural systems in other regions. The mushroom subsystem is highly benefited from the cow subsystem by making use of cow excrements as materials, which can alleviate pollution caused by excessive piles up of cow manure and rain washing down to the groundwater. Compared with the subsystems, diary-mushroom agrocirculation system has higher yield raio, lower emergy investment ratio (EIR), and higher environmental sustainable index (ESI) value. In the long run, processes with a lower percent of purchased emergy are likely to be more sustainable, of which corn plantation, cow breeding and mushroom cultivation are not aparted and formed into a circulation chain. So the dariymushroom circulation system is one of a sustainable agricultural mode adapted for this water protection area and should be promoted.
