Sustainable small-scale biogas production from agrofood waste for energy self...OriginGreenPlatform
IrBEA promotes sustainable small-scale biogas production from agro-food waste. The EU-funded BIOGAS3 project aims to develop biogas plants suitable for farms and food processors without disrupting operations. These plants would use materials like cow slurry, food waste, and pig slurry to provide on-site energy for operations like milking, processing, and building heating. Successful small-scale biogas examples from Europe and developing countries are highlighted. The presentation provides information on substrates and gas yields, and explains how interested parties can get involved through training, feasibility studies, and project implementation support.
Pyrolysis is a thermal decomposition process that converts organic material into solid, liquid, and gaseous products in the absence of oxygen. It involves heating material to 500-800°C, which causes simultaneous chemical and physical changes. There are two main types - slow pyrolysis produces more biochar, while fast pyrolysis takes seconds and yields 60% bio-oil. Rice husk, a agricultural waste, was subjected to pyrolysis between 400-650°C to produce bio-oil, gas, and biochar. The pyrolysis process has advantages such as being simple, low-cost, reducing waste and emissions, and producing marketable products, though the technology and markets are still developing.
Thermal decomposition of biomass through pyrolysis produces a mixture of gas, liquid, and solid products. Ensyn has developed a commercial pyrolysis technology called RTPTM that can rapidly convert biomass such as wood into bio-oil. Ensyn operates multiple commercial-scale RTPTM plants and produces bio-oil for downstream applications. Ensyn recovers high-value chemicals from bio-oil to sell for uses such as food and polymers, and uses the remaining bio-oil for fuel and energy applications. Ensyn's business model focuses on maximizing value by optimizing multiple product streams from pyrolyzing biomass.
Valorization of Organic Waste by Means of Compression Frictional TreatmentEnginuity
The document describes a novel method called Compression Frictional Treatment (CFT) that utilizes friction and compression in a Rotary Compression Unit (RCU) to transform organic waste into higher value fuels and products without external heat. CFT can process materials like corn stover, poultry litter, and anaerobic digestate. When applied to corn stover, CFT increased the carbon content and heating value while decreasing moisture, transforming it into a charcoal-like material. CFT can also dry poultry litter and anaerobic digestate, increasing their heating values, and kills bacteria present. The treated wastes have potential as alternative fuels or fertilizers.

1. Conduct a feasibility study to determine the optimal biogas technology based on the available input materials and site conditions.
2. Complete detailed engineering and design plans after optimizing for legal/economic factors.
3. Choose between wet and dry fermentation processes based on input materials and costs, ensuring the proper conditions for bacterial growth.
The document describes plans for an integrated cow farm, biogas, and organic fertilizer operation. Cow manure and other organic waste would be converted into biogas via anaerobic digestion. The biogas could generate electricity and the remaining digestate would be further processed into organic fertilizer granules and liquid fertilizer. The operation would include facilities to house cows, digesters, a biogas purification system, fertilizer processing equipment, storage, and buildings to support a staff of 20 people. The project aims to profitably treat waste and produce renewable energy and fertilizer products.

This document discusses sustainability certification of biomass. It outlines the growing public concern over the sustainability of biomass production which has led to the development of certification standards. Key criteria for sustainable biomass production standards include greenhouse gas balances, avoiding competition with food production, protecting biodiversity, and ensuring environmental protection and prosperity. The EU Renewable Energy Directive lays out sustainability criteria for biofuels, including minimum thresholds for greenhouse gas savings. Certification systems involve accreditation bodies, control and verification of production according to set standards and principles. Implementation in the Netherlands and Germany involves national certification schemes that must meet or exceed EU requirements. Africa will need to ensure biomass supplies to Europe are certified as sustainable under these standards.
This document discusses climate smart agriculture as the way forward for food security in a changing climate. It outlines the triple challenge of producing more and better quality food for more people while adapting to and mitigating climate change. It provides examples of practices for building resilient food systems like rainwater harvesting, conservation agriculture, nutrient management, agroforestry, reducing food losses, and managing risks. The document emphasizes the need to account for agriculture in climate actions and financial mechanisms, given agriculture's importance and the specific needs of smallholder farmers. It lists several FAO submissions to the UNFCCC on these topics and calls for linking food security and climate change issues in international forums like the Committee on World Food Security.
Livestock and Climate Change - Tara Garnett, Food Climate Research Network, U...guycollender
This document summarizes livestock and dairy production's significant contributions to greenhouse gas emissions and discusses options for reducing emissions. Livestock accounts for around 15-18% of global GHG emissions. Meeting projected global demand increases in meat and dairy by 2050 without changes would be unsustainable. Technological improvements could reduce emissions by 13-30% by 2020 and 50% by 2050, but reductions in consumption are also needed to see an actual decrease in emissions. To meet UK climate targets, livestock consumption may need to be cut by 11-36% by 2020 and 48% by 2050. Approaches that focus on ecological constraints and meeting needs rather than demand are recommended.
This document discusses the ecological footprint of livestock production and methods for assessing the environmental impacts of different food production systems through life cycle assessment (LCA). It provides examples of using LCA to compare the greenhouse gas emissions of producing different animal products like pork, chicken and eggs. It also discusses using LCA and data envelopment analysis to benchmark dairy farms and identify opportunities to reduce environmental impacts and increase economic efficiency.
Barilla Sustainable Farming: a Smart Agriculture Tool in the Climate Change EraData Driven Innovation
Luca Ruini - The Barilla Sustainable Farming (BSF) model is applied >1.000 Italian farmers providing the Barilla Handbook and Granoduro.net® - a Web Decision Supporting System (DSS) designed to assist day by day farmers taking also account local weather forecast. Results show that low input agronomic practices are environmentally friendly (- 36% GHG) and increase net income of farmers (up to 31%). Granoduro.net contributes in reducing carbon footprint (-10%) and costs for pesticides and fertilizers (- 10%). BSF DSS based is an adaptive agriculture tool in Climate Change weather condition.
The document provides an overview of a training module on bioenergy innovations in waste management and the circular economy in the EU. The module will include lectures, discussions with experts, and interactive exercises on topics like: anaerobic digestion and production of biogas and fertilizer, the environmental benefits of biogas, dark fermentation and biohydrogen production, methods to intensify anaerobic digestion, and implementing biogas stations at solid waste landfills. The goal is to provide experience on EU bioenergy innovations for waste management.
To accelerate implementation of the Paris Agreement, the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and the International Livestock Research Institute (ILRI), in collaboration with the Global Research Alliance on Agricultural Greenhouse Gases (GRA) and the Food and Agriculture Organization of the United Nations (FAO), will facilitate a science-policy dialogue on measurement, reporting and verification (MRV) to detect mitigation impacts in livestock production systems. Country experiences will be shared to identify practical innovations for the collection and coordination of activity data and improved emission factors.

Approach: identify + analyse post-harvest
measures
4
1. Identify loss-reducing measures
2. Estimate or measure direct effects:
• extra energy costs
• packaging material
• transport
• etc.
3. Estimate or measure indirect effects:
◦ available food %
◦ emissions waste management
4. Calculate impacts of crop and postharvest operations
5. Compare scenarios

Case: tomato crates vs. baskets
Comparison:
Traditional baskets:
● made from by-product (cane)
● stacking baskets → tomato
damage
Crates:
● made from plastics
● stackable, reduced tomato
damage

Research
Production & small-scale processing in Mozambique:
● Cassava cake:
o 0.168 kg CO2 per kg cassava crop equivalent,
o that is 0.685 kg CO2-eq. per kg starch
● Cassava flour:
o 0.157 kg CO2 per kg cassava crop equivalent
o that is 0.730 kg CO2-eq. per kg starch
Scenario imported maize flour from Australia:
o 0.712 per kg wheat flower equivalent
o that is 1.02 kg CO2-eq. per kg starch
Case: Cassava starch vs. imported
maize flour (Mozambique)

Research
Case: lower refrigeration
temperature in fresh supply chain
7
Improvement opportunity:
Lower temperature 7 → 5°C
Direct effects:
● Higher refrigeration energy use
Indirect effects:
● extended shelf life
● extended average storage energy
use
● reduction of losses
Supported by the Dutch
ministry of Agriculture,
Nature and Food
Quality
Generic effects:
• Refrigeration energy use per unit supplied ↑
• Percentage losses ↓
Cumulative GHG emissions per unit sold in
retail:
• For meat ↓
• For cut vegetable ↑

Food & Biobased
Research
Case: valorisation of reject ripened
mango and avocado as frozen slices
8
Selection after ripening (‘ready to eat’)
Reference situation:
reject products are fermented for biogas
frozen products are imported from
production countries
Improvement opportunity
reject products are peeled
good part is cut in slices + frozen
traded as frozen product
GHG impacting operations taken into
consideration:
• agricultural production
• mango 0.3 kg CO2-eq/kg
• avocado 1.3 kg CO2-eq/kg
• truck, ship, truck transport
• large / small-scale freezing
• organic waste management processes
Net GHG effect of improvement opportunity:
• For mango −
• For avocado +

Summarizing
Loss-reducing measures can
contribute to GHG emission
reductions per unit food supplied
... but not all loss-reducing
measures are beneficial from
climate impact perspective
