Coffee is a highly productive agricultural product in the department of Tolima. The wet fermentation process of coffee generates about 80% of the waste, which is highly contaminated with organic matter that pollutes water sources, so anaerobic co-digestion techniques are implemented in coffee wastewater using Taiwan type biodigesters. According to the study of three biodigesters fed with coffee waste and animal manure, the aim is to show their potential application in coffee farms. These biodigesters generated a biogas production with CH4 concentrations between 49.1% ± 4.6 and 58.1% ± 2.4 in volume, in addition to the benefit of the biol used as fertilizer in the crops. The biogas produced can be used for cooking and can save around USD 40.17 in natural gas. Therefore, the biodigester is a potential tool to mitigate the harmful effects of coffee cultivation on the surrounding ecosystem and can project coffee production in a sustainable direction.

Natural gas is a source of energy that comes from the earth which is depleting every day, an alternative source of energy is needed and one of the sources comes from biogas. There is an abundance of empty fruit bunch (EFB) that comes from palm oil plantation that can become a substrate for biogas production. A methodology of fermentation based on Verein Deutscher Ingenieure was used to utilize EFB as a substrate to produce biogas using biogas sludge and wastewater sludge as inoculum in wet fermentation process under mesophilic condition. Another optimization was done by adding a different water ratio to the inoculum mixture. In 20 days, an average of 6gr from 150gr of total EFB used in each sample was consumed by the microbes. The best result from 20 days of experiment with both biogas sludge and wastewater sludge as inoculum were the one added with 150gr of water that produced 2910ml and 2185ml of gas respectively. The highest CH 4 produced achieved from biogas sludge and wastewater sludge with an addition of 150gr of water to the inoculum were 27% and 22% CH 4 respectively. This shows that biogas sludge is better in term of volume of gas that is produced and CH percentage.

In recent years, the circular economy and sustainability have gained attention in the food industry aimed at recycling food industrial waste and residues. For example, several plant-based materials are nowadays used in packaging and biofuel production. Among them, by-products and waste from coffee processing constitute a largely available, low cost, good quality resource. Coffee production includes many steps, in which by-products are generated including coffee pulp, coffee husks, silver skin and spent coffee. This review aims to analyze the reasons why coffee waste can be considered as a valuable source in recycling strategies for the sustainable production of bio-based chemicals, materials and fuels. It addresses the most recent advances in monomer, polymer and plastic filler productions and applications based on the development of viable biorefinery technologies. The exploration of strategies to unlock the potential of this biomass for fuel productions is also revised. Coffee by-products valorization is a clear example of waste biorefinery. Future applications in areas such as biomedicine, food packaging and material technology should be taken into consideration. However, further efforts in techno-economic analysis and the assessment of the feasibility of valorization processes on an industrial scale are needed.

AbstractCoffee cultivation in Central America provides goods and services at local, national, and international levels. Climate change is likely to affect the magnitude and continuity of these benefits by reducing the land suitability for coffee cultivation. To quantify the impacts of climate change on land suitability, we use the Bayesian network model Agroecological Land Evaluation for Coffea arabica L. (ALECA) and estimate the land suitability for coffee production in 2000, 2050, and 2080 under three climate change scenarios based on relative concentration pathways (RCPs) 2.6, 4.5, and 8.5. Results indicate that even under the less severe climate scenarios, over half of the current coffee area in Central America will experience a decline in its land suitability for coffee production, from excellent or good to moderate and marginal, and that the change will not happen in the more distant future of 2080, but by 2050. Under RCP 8.5, most coffee areas become of marginal and moderate suitability. The findings show that the continuity of coffee cultivation in a large portion of coffee areas in Central America is under threat and that farmers and policy-makers should develop adaptation portfolios for their farms and regions in a timely manner.

This article investigates how biogas technology can facilitate the deployment of municipal circular bio-economic solutions within the energy and agrarian sectors in Denmark. The emphasis is on the regional climate policy and the existing biogas technology concepts, within a decentralized energy market located in the Southern part of Zealand. The case analysis will identify how such technology can be utilized as a lever for future “extraction-activities,” as for example protein, wax, and furfural substrates. Within Falster & Lolland Municipalities, it is identified that 800.000 tons of animal manure is readily available for biogas production, just as 880.000 tons and 220.000 tons of unused beet tops and residual cereal straw could be feed to biogas facilities as for example co-silage materials. With a potential gas yield of approximately 897.000 MWh, composed by the crop residues alone, the challenge is how to utilize such resources the most efficient when addressing future needs for bio-products and high value materials and energy. Through the lens of Circular Bio-Economy this article addresses three themes, by which biogas technology can become an “engine” for future bioenergy solutions, where cascading activities and use of side-streams are developed: 1) production of biogas by means of local agricultural residues (beet tops, residual straw, and animal manure), combined with 2) “extraction-activities” as furfural and wax from straw, as well as protein from beet tops. Besides this 3) opportunities for upgrading the biogas and distributing it on a natural gas network, hereby enlarging the supply market for energy services from the biogas plant and facilitating the development of a more “integrated energy system,” currently being promoted by the European Commission. This article concludes on a step-by-step approach to utilize biomass residues more efficiently in light of the CBE concept and cascading approach, and the available biomass resources within the specific case area addressed.

The aim of this paper was to review the piggery waste management aspects in several countries of the world. Intensive livestock production produces significant quantities of waste that must be managed to protect water, air, and crop quality. The high demand of modern animal production has been influenced by the rapid growing populations as a result of rapid economic growth and increase in community living standards which is associated with the accelerated generation rate of solid waste causing a serious worldwide challenge. Piggery waste is said to be one of the most important causative agents of environmental pollution in most parts of the world. A growing pig population is unavoidable because it is a convenient source of protein to the growing human population and at the same time this means increasing piggery waste. Animal manure can provide nutrients for crops and fish production and input for biogas production, but if not managed, then this can also have a negative impact on the environment. Nevertheless, there are few countries who are considering legislation in relation to manure management.

The objective of this research is to present a review of the current technologies and pretreatments used in the fermentation of cow, pig and poultry manure. Pretreatment techniques were classified into physical, chemical, physicochemical, and biological groups. Various aspects of these different pretreatment approaches are discussed in this review. The advantages and disadvantages of its applicability are highlighted since the effects of pretreatments are complex and generally depend on the characteristics of the animal manure and the operational parameters. Biological pretreatments were shown to improve methane production from animal manure by 74%, chemical pretreatments by 45%, heat pretreatments by 41% and physical pretreatments by 30%. In general, pretreatments improve anaerobic digestion of the lignocellulosic content of animal manure and, therefore, increase methane yield.
