Food and Agriculture Organization (FAO) The Food and Agriculture Organization (FAO), established in 1945, is a UN specialized agency that provides global data and expertise on agri­ culture and nutrition, fisheries, forestry, and other food and agriculture– related issues. FAO is the UN system’s largest autonomous agency, with headquarters in Rome, 78 country offices and 15 regional, sub–regional, and liaison offices, including one located in Washington, D.C. FAO’s highest policy–making body, the biennial General Conference, comprises all 183 FAO member countries plus the European Commission. The General Conference determines FAO policy and approves FAO’s reg­ ular program of work and budget. The 31st Conference, meeting in November 1999, re–elected Director–General Jacques Diouf (Senegal) to a second six–year term through December 2005. Each biennial Confer­ ence elects a 49–member Council that meets semi–annually to make rec­ ommendations to the General Conference on budget and policy issues. The North America region, which comprises the United States and Can­ ada, is allocated two seats on the Council and one seat each on FAO’s Program, Finance, and Constitutional and Legal Matters (CCLM) Com­ mittees. The United States holds the North American seats on the Finance and Joint Staff Pension Committees through December 2003. Canada holds the North American seat on the CCLM and Program Committees through December 2003. The United States participated at the World Food Summit: Five Years Later meeting held at FAO headquarters June 10–13, 2002, to discuss progress towards attaining the 1996 World Food Summit target of reduc­ ing the world’s number of hungry and malnourished by half by 2015. The United States presented new initiatives to improve agriculture productivity as a significant contribution toward meeting that goal. U.S. Secretary of Agriculture Ann Veneman, leading the U.S. delegation, joined other min­ isters and heads of state and government in adopting a Declaration, “The International Alliance Against Hunger,” which reiterated the goals of the 1996 World Food Summit and stated, inter alia, “we are committed to

Pretreatment Strategies for Enhanced Biogas Production From Lignocellulosic Biomass

The waste-to-wealth concept aims to promote a future sustainable lifestyle where waste valorization is seen not only for its intrinsic benefits to the environment but also to develop new technologies, livelihoods and jobs. Based on the concept of waste valorization and circular economy, this review aims to provide an overview of present trends and future potential in the conversion of residues from different food sectors into valuable bio(nano)materials.

Waste-to-wealth: biowaste valorization into valuable bio(nano)materials

Engineered mycelium composite construction materials from fungal biorefineries: A critical review

Nigeria is a developing country with an insufficient supply of energy to meet the continuously growing demand. However, there are several biomass resources available within the country. This paper presents a desk review, which investigates the potential resources for biomass energy generation within the country. Energy policies to aid biomass use as an energy source within the country were also reviewed. Biomass resources identified within Nigeria include forest residues, agricultural residues, human and animal wastes, aquatic biomass, and energy crops. However, several of the resources, particularly agricultural residues, have competing uses, such as livestock feed and soil rejuvenation. An estimation of the technical energy potential of the biomass resources revealed that about 2.33 EJ could be generated from the available resources in Nigeria. Agricultural residues have an energy potential of about 1.09 EJ, with cassava, maize, oil palm, plantain, rice, and sorghum being the major contributors. Animal wastes, municipal solid waste, and forest residues have energy potentials of 0.65, 0.11, and 0.05 EJ, respectively. The potentials of wood fuel and charcoal are 0.38 and 0.05 EJ, respectively. The study found that despite the available potential and existing policies, not much has been done in the implementation of large-scale bioenergy within the country. However, there has been laboratory and research-scale investigations. The review suggests that more policies and stronger enforcement will aid bioenergy development within the country. From the review, it has been suggested that the agricultural sector needs to be developed to generate more biomass resources. More research, development, and implementation have to be carried out on biomass resources and bioenergy generation processes. The production of non-edible energy crops in marginal lands should also be considered prime to the development of bioenergy within the country.

An Assessment of Potential Resources for Biomass Energy in Nigeria

Potential depletion of fossil fuel and climate change have globally accelerated the demand in renewable and alternative energy. Most of the Southeast Asian countries have an abundance of biomass sources for the energy sector due to their agriculture-based economy and enormous forest resources. Therefore, the study aimed at highlighting an overview of biomass energy in the Southeast Asia countries to convey the environmental and economic benefits from the available biomass sources in the region. In order to achieve the aim, the study synthesized and evaluated the biomass sources, energy potential, utilization, and management in the region, based on the published research papers, review papers, and country reports. It was found that the major biomass sources in this region were fuelwood, wood residues, rice husk, rice straw, sugarcane residues, oil palm residues, and coconut residues. The total annual quantity of the biomass potential from agriculture and forest sector in the region was estimated at more than 500 million tons per year and equal to over 8000 million gigajoules of total energy potential. In order to implement the sustainable utilization of biomass sources, the study specified the barriers and challenges of biomass utilization in these countries and proposed a sustainable approach of biomass energy, by comparing the way of traditional biomass utilization.

Biomass Energy: An Overview of Biomass Sources, Energy Potential, and Management in Southeast Asian Countries

Nowadays, drying methods for municipal solid waste quality improvement have been adopted in the developed and developing countries to valorize wastes for a renewable energy source, reduce dependency on fossil fuel and keep safer disposal at landfills. Among them, biodrying, biostabilization, thermal drying and solar drying are the most common. Drying of municipal solid waste could offer several environmental and economic benefits. Therefore, this review highlighted the drying methods for municipal solid waste quality improvement around the world and compared them based on the reduction of moisture, weight and volume of municipal solid wastes against drying temperature and time by using statistical analysis. It was observed that the drying temperature of different drying methods accounted for 115 ± 40°C for thermal drying, 59 ± 37°C for solar drying, 55 ± 15°C for biodrying and 58 ± 11°C for biostabilization. Among the drying methods, thermal drying provided the shortest drying time. The moisture reduction, weight reduction, volume reduction and heating value increase of municipal solid waste could vary with drying temperature and time. Finally, the benefits and drawbacks of different drying methods were specified, and recommendations were made for the future efficient drying.

Drying methods for municipal solid waste quality improvement in the developed and developing countries: A review

Nowadays it is important to limit the use and combustion of fossil fuels such as oil and coal. There is a need to create environmentally acceptable projects that can reduce or even stop greenhouse gas emissions. In this article, we dealt with the objectives of energy policy with regard to environmental protection, waste utilization, and conservation of natural resources. The main objective of the research was to assess the possibility of the use of spent coffee grounds (SCG) as fuel. As a part of the solution, the processing of coffee waste in the form of pellets, analysis of calorific value and combustion in the boiler were proposed. The experiments were done with four samples of pellets. These samples were made from a mixture of wood sawdust and spent coffee grounds with ratio 30:70 (wood sawdust: spent coffee grounds), 40:60, 50:50 and 100% of spent coffee grounds. The calorific values were compared with wood sawdust pellets (17.15 MJ.kg−1) and the best lower calorific value of 21.08 MJ.kg−1 was measured for 100% of spent coffee grounds. This sample did not achieve the desired performance during the combustion in the boiler due to the low strength of the sample.

Spent coffee ground as renewable energy source: Evaluation of the drying processes.

Nowadays, waste-to-energy has become a type of renewable energy utilization that can provide environmental and economic benefits in the world. In this paper, we evaluated the quality of twelve biodegradable waste samples from Myanmar by binder laboratory heating and drying oven at 105 °C. The calculation methods of the Intergovernmental Panel on Climate Change (IPCC) and Institute for Global Environmental Strategies (IGES) were used for the greenhouse gas emission estimation from waste disposal at the open dumpsites, anaerobic digestion, and waste transportation in the current situation of Myanmar. Greenhouse gas (GHG) emission and fossil fuel consumption of the improved biodegrade waste utilization system were estimated and both were found to be reduced. As a result, volume and weight of the biodegradable wastes with 100% moisture reduction were estimated at approximately 5 million cubic meters per year and 2600 kilotonnes per year, respectively, in 2021. The total GHG emissions in the current situation amounted to approximately 1500 and 1800 Gigagrams of CO2-eq per year in 2019 and 2021, respectively, while the total GHG emission avoidance from a sustainable approach amounted to 3500 and 4000 Gigagrams of CO2-eq per year, respectively. The study aimed at highlighting the utilization of biodegradable wastes as a clean energy source in developing countries.
