Biotechnology - Biofuel

These flashcards cover key concepts related to biotechnology and biofuels, including definitions, benefits, concerns, and types of biofuels.

Biotechnology

The use of living organisms to make useful products, including fuels.

Biofuel

Fuels made from renewable plant or animal materials.

Bioethanol

A biofuel made from sugar or starch crops, mainly used blended with petrol.

Biogas

A fuel produced from food waste and manure using bacteria, used for cooking and electricity.

Biodiesel

A biofuel made from plant oils, used in diesel engines.

Renewable resources

Natural resources that can be replenished naturally over time, such as plants.

Food crops

Crops grown for human consumption, such as corn and sugarcane.

Fossil fuels

Limited energy sources that form over millions of years and are non-renewable.

Carbon footprint

The total emissions produced directly and indirectly by an individual or organization.

First-generation biofuels

Biofuels produced from food crops, such as corn and sugarcane.

Second-generation biofuels

Biofuels made from non-food biomass, like agricultural residues.

Deforestation

The clearing or thinning of forests, often for agriculture or biofuel production.

Greenhouse gas emissions

Gasses emitted from human activity that contribute to climate change.

Air pollution

The presence of harmful substances in the atmosphere, often due to combustion.

Sustainable energy cycle

A system of energy production and consumption that can be maintained without depleting resources.

Palmoil

An oil extracted from the fruit of the oil palm, used in biodiesel production.

Organic sources

Natural materials derived from living organisms, including plants and waste.

Agricultural by-products

Residual materials from agricultural production, like crop residues.

Climate change impact

The effects of climate change on the environment and society.

Electricity generation

The process of producing electric power, often using biofuels.

Sustainable waste management

The practice of treating waste in a way that supports the environment.

Carbon-neutral

Releasing no net carbon dioxide into the atmosphere.

Competition with food production

When biofuel production uses land or resources needed for growing food.

Water use

The amount of water consumed, which can be high in biofuel crop farming.

Liquid fuel distribution system

Established networks for distributing liquid fuels, which can include biofuels.

Complex conversion processes

Advanced methods used to transform biomass into fuels.

High oil yield

The amount of oil produced per hectare of land.

Issues with biofuels

Concerns related to the impact of biofuel production on food prices and the environment.

Energy substitutes

Alternatives to traditional fossil fuels that can be derived from biofuels.

Green technology

Innovative methods that aim to reduce environmental harm.

Utilization of waste

Making use of discarded materials for energy production.

Economic growth

Increase in the economic activity, which biofuels can contribute to.

Environmental damage

Harm to natural ecosystems resulting from human activities.

Dependence on fossil fuels

Reliance on non-renewable energy sources for power.

Emission reduction

Strategies to lower the output of harmful gases.

Transportation fuels

Fuels specifically used to power vehicles.

Adverse environmental impacts

Negative effects on the environment caused by certain practices.

Biomass

Total mass of organic material from living or recently living organisms.

Food prices

The market costs of food items, which can be affected by biofuel production.
