Biomass For Energy

Biomass is seen as one of the most dominant future renewable energy sources. In detail, agro-industrial by-products represent a cheap, renewable, and abundant feedstock useful for several new products, including biochemical, biomaterials, and above all biogas, which are taking on an ever-increasing role in Italy. In this context, the tomato chain was analysed aiming at estimating the amount of processed tomato and the related waste production as a new suitable resource for producing biofuel as a new frontier within the context of a circular economy. Due the importance of the tomato industry, this research aims at filling gaps in the knowledge of the production and yield of the by-products that are useful as biomass for energy use in those territorial areas where the biomethane sector is still developing. This aim could be relevant for planning the sustainable development of the biomethane sector by reducing both soil consumption for dedicated energy crops and GHG emissions coming from the biomass logistic supply. The achieved results show the localization of territorial areas highly characterized by this kind of biomass. Therefore, it would be desirable that the future policies of development in the biomethane sector consider the availability and the distribution of these suitable biomasses within the territory.

Over the last few years, the concept of Circular Economy (CE) has received a lot of attention due to its potential contribution to the Sustainable Development Goals (SDGs), especially by reconciling economic growth with the protection of the environment through its grow-make-use-restore approach. The use of insects in circular production systems has been a good example of this concept as insects can transform a wide range of organic waste and by-products into nutritious feedstuffs, which then go back into the production cycle. This paper explores the potential of mealworms (Tenebrio molitor) in circular production systems by reviewing their use and applicability in several industries such as pharmaceuticals, agriculture, food, etc. Despite the high versatility of this insect and its potential as a substitute source of nutrients and other valuable components, there are still many legislative and behavioural challenges that hinder its adoption and acceptance.

Biomass For Energy

Significance There is an obvious tension between promoting forests to capture carbon and burning wood for energy. Increased demand risks unsustainable indirect changes of land use. However, modern forestry practices suggest woody biomass can be used sustainably, if forest eco-systems are well managed. Impacts Although it continues to carry a green label, debate over its sustainability may damage financial flows into the biomass sector. The sector focus on secondary and tertiary wood sources, as well as wood industry by-products, will increase. Woody biomass use for heat and power will make up a key part of renewable energy generation, particularly in heavily forested countries.

The fashion industry has to play an important role in the path towards sustainability and the circular economy. Indeed, the fashion industry is a sector with a high environmental impact; it involves a very long and complicated supply chain, which is associated with large consumption of water and energy, use of chemical substances, water and air pollution, waste production and finally microplastic generation. In particular, textiles and clothing waste has become a huge global concern. Against this background, this paper aims at analysing the existing EU measures that have an impact on the development of sustainable practices and the transition to a circular economy in the fashion industry, with a particular focus on the EU revised legislative framework on waste adopted within the Circular Economy Action Plan of 2015.

Agriculture and animal husbandry are important contributors to global emissions of greenhouse (GHG) and acidifying gases. Moreover, they contribute to water pollution and to consumption of non-renewable natural resources such as land and energy. The Life Cycle Assessment (LCA) methodology allows evaluation of the environmental impact of a process from the production of inputs to the final product and to assess simultaneously several environmental impact categories among which GHG emissions, acidification, eutrophication, land use and energy use. The main purpose of this study was to evaluate, using the LCA methodology, the environmental impact of milk production in a sample of 41 intensive Italian dairy farms and to identify, among different farming strategies, those associated with the best environmental performances. The functional unit was 1 kg Fat and Protein Corrected Milk (FPCM). Farms showed characteristics of high production intensity: FPCM, expressed as tonnes per hectare, was 30·8±15·1. Total GHG emission per kg FPCM at farm gate was 1·30±0·19 kg CO2 eq. The main contributors to climate change potential were emissions from barns and manure storage (50·1%) and emissions for production and transportation of purchased feeds (21·2%). Average emission of gases causing acidification to produce 1 kg FPCM was 19·7±3·6 g of SO2 eq. Eutrophication potential was 9·01±1·78 ${\rm PO}_{\rm 4}^{{\rm 3} -} {\rm eq}.$ per kg FPCM on average. Farms from this study needed on average 5·97±1·32 MJ per kg FPCM from non-renewable energy sources. Energy consumption was mainly due to off-farm activities (58%) associated with purchased factors. Land use was 1·51±0·25 m2 per kg FPCM. The farming strategy based on high conversion efficiency at animal level was identified as the most effective to mitigate the environmental impact per kg milk at farm gate, especially in terms of GHG production and non-renewable energy use per kg FPCM.

Due to the necessity of developing renewable energy sources, the anaerobic digestion for producing biomethane has developed significantly in the last years, since it allows to both reduce disposal treatment and produce green energy. In this field, fruit and vegetable wastes have been recently put forward, since they could represent a suitable resource for producing biomethane as a new frontier within the context of a circular economy. This study aims at filling the gap in the knowledge of the production, quantities and biogas potential production of these residues. On this basis, a GIS-based model was developed and applied to the Sicily region by investigating the specific regulatory framework as well as by analysing descriptive statistics. The results of the GIS analyses enabled the localisation of the highest productive territorial areas and highlighted where fruit and vegetable wastes are abundantly located. In this regard, about 7 million Nm3 of biogas could be produced by reusing only the fruit and vegetable residues coming from the three most representative Sicilian wholesale markets among those considered. Finally, the regulatory framework is of crucial importance in inhibiting or supporting the use of the selected biomass in a specific sector, with regard to the case study considered.

Achieving sustainable, healthy diets remains a global challenge to meet the sustainable development agenda by 2030. The purpose of this study is to derive optimal dietary recommendations for children that consider nutritional, environmental, and economic parameters of sustainability, using Lebanon as a case study. Data from the latest national food consumption survey conducted among Lebanese children were used. Optimized diets were derived using Optimeal, a software that produces similar patterns to the usual diet while considering nutrition constraints (energy, and macro/micronutrient needs), environmental footprints ((EFPs): water use, energy use, and greenhouse emissions), and cost. Three optimized diets were derived that meet the nutritional needs of children aged 4–8, 9–13, and 14–18 years, while considering EFPs and cost. Compared to the usual intake, optimized diets included higher intake of vegetables, legumes and dairy, and a decrease in saturated oils, processed meats, sugar, salty snacks, sweets, and sugar-sweetened beverages. Overall, the optimized diets decreased cost by 20% and reduced water use, energy use, and GHG emissions, by 20%, 11%, and 22%, respectively. The proposed models consider various constraints and provide sustainable solutions for decision makers within a country undergoing crises.

Circular Design

The idea of the circular economy is conceptualized as the basic transformative, integrative philosophy, which is the basis of ecological and economic policy of public-private partnership. It is found that the intensification of competition for resources leads to increased waste production and pollution, which led to the formation of an economic system. Its components are renewable energy sources, increased production of waste from production waste, minimization of food waste and improving the quality of life of all segments of society. All successful micro-industries have been found to be the product of successful business start-ups. The author identified the key factors of the circular economy: the potential of the Fourth Industrial Revolution; circular value chains based on recycled waste; leaders in the circular economy; cooperation. The analysis of the circular business model made it possible to prove that it can include one or a set of the following elements: circular design, optimal use, value recovery, network (chain) organization. Those ones represent the circular economy as a global imperative of the formation and development of its architecture.

Achieving sustainable socio-economic development requires approaches that enhance resource use efficiencies and can address current cross-sectoral challenges in an integrated manner. Existing evidence suggests an urgent need for polycentric and transformative approaches, as global and local systems have come under strain. This study conducted a systematic literature review at the global level to assess the progress made towards achieving a circular economy between 2010 and 2020, a period covering the formulation of the Sustainable Development Goals (SDGs) and the initial five years of their implementation. The focus was on the potential of improved water and energy use efficiency, linking them to food production within the context of a circular economy. Identifying successes, opportunities, challenges, and pathways towards a circular economy from the literature review facilitated developing a conceptual framework to guide strategic policy formulations towards a more sustainable economy. A combination of transformative approaches is analysed in an integrated way in response to the 2030 global agenda on sustainable development. Thus, the study is informed by the initiatives to attain SDGs and mitigating negative environmental impacts due to waste and pollution. The premise is to enhance transformational change as a catalyst for employment creation and the attainment of a green economy while reducing waste. Transformative approaches have been identified to provide pathways towards global climate targets and protection of the environment from further degradation. They are a catalyst to achieve SDG 12 on ensuring sustainable consumption and production patterns.

The burning of fossil fuels emits greenhouse gases (GHGs), especially CO2, possibly causing climate change. Environmentally friendly energy development has enormous implications for developing countries as major emitters due to their rapid economic and population growth. This paper presents an overview of Turkey's efforts to reduce GHG emissions by reforming energy pricing, promoting energy efficiency, and using renewable energy sources. With some possible options, the paper concludes that the reduction of emissions can only be achieved when policies are supportive and well targeted, standards and incentives are realistic and flexible, and the public is actively responsive to environmental degradation. Turkey's high rate of energy-related carbon emissions growth is expected to accelerate, with emissions climbing from 57 million tons in 2000 to almost 210 million tons in 2020. Carbon intensity in Turkey is higher than the western developed national average. Energy-intensive, inefficient industries remain under government control with soft budged constraints, contributing to undisciplined energy use in Turkey.
