“…Coproducts play an important role in the economic viability at all scales and from S2 to S5, reducing the green diesel MSP by 63.8% in S5 on a small scale. Similar results were obtained by Mayer et al, 65 in which coproducts of a small‐scale biorefinery from sugarcane made bioethanol production viable. Another study tested the viability of hydrotreated jet fuel from Jatropha, and obtained a price reduction of 43% in the jet fuel by selling coproducts 23 .…”

In this study, three scales of a biofuel-driven biorefinery were evaluated in technoeconomic, environmental and geospatial terms for green diesel production from macauba oil. The results show that the relative capital expenditure on the small scale is four times higher than that on the large scale, being significantly affected by the hydrogen facilities. However, coproducts, tax deductions for family farming and carbon credits can sustain the small-scale production of green diesel. The carbon footprint of the green diesel is lower than that of commercial biofuels. Finally, the geospatial analysis applied in Brazil reveals that macauba cultivation with low landuse impact can be implemented near small-scale biorefineries for local consumer markets. Therefore, the feasibility of the small scale depends on coproducts, public policies, decentralized hydrogen production and catalysts for low-hydrogen demand routes. This biorefinery concept can decentralize the biofuel sector and make use of several types of biomasses besides macauba, generating socio-economic and environmental gains.

“…This cluster includes topics related to NCS production process optimization and greening research lines. It includes the design, selection, and adoption of appropriate technologies for production lines comprising extraction, clarification, and by-product use for small producers (Beeram et al 2020 ; Mayer et al 2020 ; Nicolas Galvis et al 2020 ). These technologies mainly focus on energy conservation and thermal efficiency (Velásquez et al 2021 ; Venkata Sai and Reddy 2020 ), environmental performance and sustainability of production units (Quezada-Moreno et al 2021 ), supply chain and commercial characteristics (Chen et al 2021 ), and mathematical and simulation approaches (Baqueta et al 2022 ).…”

Key Drivers for Non-Centrifugal Sugar Cane Research, Technological Development, and Market Linkage: A Technological Roadmap Approach for Colombia

Food science innovation depends on consumers’ needs and is currently seeking functional food with health effects. Non-centrifugal cane sugar (NCS) is known for its potential health effects, but there is a lack of holistic analysis on technological advancement and socio-economic and market trends for decision-making in the development of the technology. The aim of this article was to analyse the research trends, recent patents, and market trends and niches for NCS to structure an NCS technological roadmap. Scientometric, bibliometric methods, and global and local market information on NCS were used. Comprehensive analysis of the worldwide research trends and patents on NCS processing and of the growth of the main niche markets for Colombian NCS exports in the last five years was conducted. Finally, with the information obtained, an NCS technological roadmap was structured, which can be used as a tool for planning innovation processes and supporting the development of new research using market information and new norms forged by the COVID-19 pandemic for Colombian case. Furthermore, the methodological design could be used for other NCS producer countries.

Soil compaction after initial soil tillage for crop establishment has been a major problem in crop fields because of its deleterious effects on soil functioning and crop performance. Therefore, the study aimed to determine the degree of compaction, soil air capacity, near-surface optimum ratios, and water retention characteristics in a sandy loam. Dystrophic Paleudalf initially under different tillage methods for sugarcane crop but without tillage for two seasons in southern Brazil. Initial soil tillage systems consisted of no-tillage (NT), compacted no-tillage (NTC), conventional tillage, and chiseling of no-tillage (Ch). Disturbed and undisturbed soil was sampled from 0 to 10, 10 to 20, 20 to 40, and 40 to 60 cm layers to determine degree of compaction, air capacity, near-surface optimum ratios, soil water retention characteristics, and soil physical quality index S. Initially, NT treatment had the significantly ( p < 0.05) lowest degree of compaction (87%), highest soil air capacity (0.104 cm3 cm−3), air capacity/total porosity ratio (0.261), and better water retention characteristics in the surface layer. Over time, Ch had improved the structure of the subsurface soil layers with the lowest degree of compaction (≈88%) and highest air capacity (≈0.140 cm3 cm−3), while the measured indices were poor in NTC. Irrespective of tillage, the surface layer showed resilience during the years without soil disturbance with low degree of compaction, increased water retention, and air capacity. NT could be a good soil management option for sugarcane production, while mechanical chiseling is advocated for ameliorating compacted soils.
