TESTE DEIN WISSEN

bio-metrics on a behavior level vs an environmental level

Lösung anzeigen
TESTE DEIN WISSEN

behavior level - the shopping center in Zimbalwe, architect Mick Peare looked at ways to control temperature inside, incorporated self cooling termite mounds into the building design.


envionmental level - the cardboard to caviar project in wakefield, yorkshire. waste cardbaord was collected and shredded then used as horse bedding, when cleaned out waste is fet to composte pit worms, then to sturgeon fish to get cavier. £300 per 100g. cheaper.

TESTE DEIN WISSEN

Why does increasing crop yield benefit the environment?

Lösung anzeigen
TESTE DEIN WISSEN

- to help meet food demand

- until artificial meat is in production, it gives livestock food

- minimizes pollution risk of imports

- to migrate the effects of climate change 

- hybridisation can get varied characteristics into yield

List 6 ways humans use wood

Lösung anzeigen
TESTE DEIN WISSEN

1. fuel - hardwood burns for longer 

2. building - used as a construction material

3. furniture - for chairs, tables and beds

4. instruments - ebony wood is used to make woodwind instruments

5. sports - such as ash baseball bats

6. sawdust - shavings for animal bedding

TESTE DEIN WISSEN

List some advantages of biodiesel as a fuel

Lösung anzeigen
TESTE DEIN WISSEN

- biodiesel is a renewable energy source

- there is excess production of soyabeans, this is an economic way to utilize it

- it is less polluting than petrol or diesel

- it would extend the life of catalytic converters

- it can be blended with other oils or energy sources

- it can be distributed through fuel pumps

- the lubrication properties could extend engine life


E.g Russia export food grains but are limited to how much can be exported

TESTE DEIN WISSEN

the difference between growing algae in an open system compared to an enclosed system

Lösung anzeigen
TESTE DEIN WISSEN

open system 

- if not monitored could get parasite/disease

- a track shaped oval pond and loop

- open to the air, stirred with a paddle to move water and prevent sedimentation 

- temperature and water movement is important to penetrate layers of algae so they can photosynthesis 


closed system 

- possible to grow more than one species of algae because the CO2 produced is captured/re used 

- its more expensive than open system 

- brings up the 'food or fuel' argument, using space that could have been crops

TESTE DEIN WISSEN

How textile production of cotton is an issue, how it can be lowered

Lösung anzeigen
TESTE DEIN WISSEN

- cotton industry makes up 40% of the textile market 

- main issue is the lack of infrastructure and legislation to protect the environment

- by products of cotton include lignin, carbohydrates and minerals are recyclable

- cotton plant stalks not used for cotton are burned, to get zero emissions the waste would need used for biomass.

TESTE DEIN WISSEN

difference between how vegetable oil and olive oil are collected for use

Lösung anzeigen
TESTE DEIN WISSEN

vegetable oil - is obtained by extracting the kernel of a nut or fruit, often by dissolving the crop in a solvent.


olive oil - is the only oil that can be consumed by humans without being refined


some coutnries have banned oils containing trans-fats because it leads to health problems

TESTE DEIN WISSEN

Main 5 issues that textile companies face.

Lösung anzeigen
TESTE DEIN WISSEN

1 - promoting environmentally friendly textiles for clothing 


2 - all governments should introduce environmental legislation 


3- increase consumer awareness e.g wash at low temp


4 - encourage recycling of clothes/textiles


5 - train staff on sustainability issues

TESTE DEIN WISSEN

Define biofuels and the UK's RTFO

Lösung anzeigen
TESTE DEIN WISSEN

Bio fuels are produced from organic material, including plant materials and animal waste. 


RTFO - renewable transport fuel obligation. 

in 2007, suppliers were compeled to use 5% biofuels by volume of diesel, it was estimated to save 1 million tonnes of carbon emissions


- for biofuels to be used effectively in the UK, modifications need to be made

TESTE DEIN WISSEN

What can governments do to lower textile environmental impact? Give an example.

Lösung anzeigen
TESTE DEIN WISSEN

1. develop environmental legislation to reduce toxic chemicals used in fabric production


2. implement behavior change  


3. develop measures to ensure countries have a traceable supply and manufacture chain


4. fund initiatives to provide means to process environmentally friendly textiles


e.g 2013 study, river around Tirupur in India was done to check its condition, the 'pollution control board' found it was understaffed and underfunded without experience. the local textile factory exported clothes for gap + tommy hilfiger.

TESTE DEIN WISSEN

green-space ran 'detox my fashion' 


- the idea that fashion brands make new clothes when people throw out old trends


- they mainly challenged Nike and Adidas to be the first clean water champions by getting rid of toxic, persistent and hormone disrupting chemicals from their production in July 2011


- two days after the campaign release, MSN mannequins were found around the worldwide locations with the Chinese symbol for water 


- Puma was the first to publically commit to elliminating toxic chemicals from its lifecycle by 2020

TESTE DEIN WISSEN

What is the cycle of algae production as a biofuel?

Lösung anzeigen
TESTE DEIN WISSEN

sun -> algae -> oil extraction -> protein residue -> biofuel production


underproduction-> existing technology -> CO2 -> algae


- its a continuous cycle, no waste 

- protein residue can be used as animal feed

- can be grown in open or closed systems


- some by products of algae can be used in pharmaceutical production e.g gavison for indigestion  

- waste water can be used as fertilizer
