1. The document discusses the potential benefits and drawbacks of installing anaerobic digestion (AD) systems on farms.
2. Benefits include making use of livestock manure and other farm waste as feedstocks, as well as flexibility in feedstock use and ability to generate heat and electricity. However, poor infrastructure access and high maintenance needs could be drawbacks.
3. The benefits of AD may be greatest when fully integrated into the farming system, such as with housed livestock providing manure, rather than as a standalone enterprise. Small farms could cooperate but transport costs would be higher.
1. The document discusses energy flow through ecosystems, including trophic levels, producers, consumers, food chains, and energy pyramids. Producers, like plants, use photosynthesis to convert sunlight into chemical energy stored in glucose.
2. Consumers that eat producers are primary consumers, while those that eat other consumers are secondary or tertiary consumers. Much of the energy is lost at each trophic level, following the 10% rule.
3. Food chains show the transfer of energy between organisms, while food webs show complex interconnected feeding relationships within an ecosystem. Energy pyramids illustrate how available energy decreases with each trophic level.

The Brussels Development Briefing n.60 on “The future of food and agricultural transformation” organised by CTA, the European Commission/EuropeAid, the ACP Secretariat and CONCORD was held on Wednesday 26 February 2020 (9h00-13h00) at the ACP Secretariat, Avenue Georges Henri 451, 1200 Brussels.
The briefing presented trends and discussed the sustainable and healthy food systems, the future of work in agriculture and the need for new skills in very complex food chains, the effects of disruptive innovations, fair and inclusive value chains and trade.
The audience was made up of ACP-EU policy-makers and representatives of the EU Member States, civil society groups, research networks and development practitioners, the private sector and international organisations based in Brussels as well as representatives from ACP regional organisations.
The document discusses how Hawaii is impacted by climate change and outlines several actions that can be taken to address it, including transitioning to renewable energy sources like solar and wind power, improving mass transit and eco-friendly transportation options, making farming more sustainable by reducing food imports and going organic, and creating "green collar" jobs in these emerging industries.
This document summarizes research into the impacts of bioenergy maize cultivation on land rental prices, the environmental footprint of maize production, and the economic costs and benefits of maize production for anaerobic digestion (AD) in the UK. The research included a literature review, economic and environmental modeling, and four case studies of AD plants of various sizes. Preliminary results found localized increases in land rental prices near AD plants, decreases in artificial fertilizer use due to digestate, and economic stability and diversification for farmers. Potential risks included impacts on soil, water quality, and displacing food crops.
Technological advancements in blockchain and cryptocurrencies have shown great promise for the possibilities in many sectors, but is it possible for energy-consuming technology to coexist, even further thrive with nature? We believe it can. More so, can these technologies enable us to push beyond sustainability to regeneration and to foster the growth of a more beautiful planet?

A life cycle assessment perspective of some foods (22 nov 2013 life cycle logic)Andrew D Moore
Life cycle assessment (LCA) looks at the environmental impacts of a product over its entire life cycle from material acquisition through production, use and disposal or recycling. For food, LCA can examine impacts from farm to fork. Studies have found different hotspots for different foods, such as production for solar PV, farming for milk, and cooking for pasta. Hotspots can change depending on how and where food is grown and cooked. Food waste across the supply chain also contributes significantly to impacts. Using LCA can help identify opportunities to improve sustainability.
Mercury is a toxic substance that causes significant environmental damage. It is commonly found in fluorescent light bulbs, with hundreds of millions of bulbs containing mercury being disposed each year, often ending up in landfills. This releases mercury into the environment where it accumulates up the food chain and can be harmful, especially for children and pregnant women, if ingested through contaminated fish. Replacing fluorescent light bulbs with LED bulbs, which contain no mercury, can help address this issue by removing the need for mercury-containing bulbs and their disposal, reducing environmental mercury levels. One project replacing over 450,000 fluorescent bulbs with LEDs will have a meaningful positive impact on reducing mercury.
The document discusses renewable energy sources as alternatives to fossil fuels. It notes that fossil fuels are running out and discusses various renewable energy sources like solar, wind, thermal, biomass, hydrogen, and ocean energy. Specific details are provided about India's potential from solar and wind energy. While India has good potential from these sources, current usage is still below capacity. The conclusion advocates increasing renewable energy projects to help save the earth for future generations as coal resources will be depleted.
Energy Farmers - Bioenergy and BiomassEuan Beamont
Through new agricultural systems and bioenergy projects, the company aims to reduce greenhouse gas emissions from agriculture while creating new revenue streams for farmers. The company has developed engineering and agricultural skills to create bioenergy and waste-to-energy projects. Their goal is to be a leading agricultural biomass development company in Australia by providing pathways between biomass resources and technology.
Students in an applied science course worked in groups on a project about global warming and renewable energies. They created brochures with information on how to save energy in daily life. The students then attempted to reduce their own electricity, shower time, gasoline, and meat consumption by 10-50% over a period of time. 88% of students were able to reduce their energy use by at least 10%, supporting the hypothesis. The assignment was modified over time based on student feedback to improve the learning experience.

This document discusses different forms of energy and energy transformations. It explains how people historically relied on burning wood and coal for fuel and used horses and donkeys to transport goods and people. Now, buildings use electricity for light and vehicles like cars and airplanes run on gasoline or diesel fuel and are used for transportation. The document also discusses how work is a measurement of force over distance and is measured in joules. Energy transformation diagrams show the inputs, converters, and outputs of energy. Photosynthesis is highlighted as the process where plants transform light and chemical energy from water and carbon dioxide into chemical energy in glucose. Human and animal bodies rely on respiration to transform the chemical energy in food into energy for movement, keeping warm, and releasing waste
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
